Considering an M11 in .177 and although I have a ton of lead in .22 and I've read all the posts about this pcp in .25 . . . Curious, for those of you that have one, would this make a good high power .177 NSA launcher?
Please tell me if I'm being foolish ;D
I have satisfied my power hunger with an AEA Challenger in .30, which I want to do a write up on soon, so now looking for something that can take rats from a long distance, but can also turn up the power for heavy .177 slugs.
-
I can't speak to the M11 specifically with personal experience, so I'm not a ton of help there. I will say it generally takes a gun with a lot of headroom in the power department to do .177 slugs justice. It pretty hard to sling those little slugs at the speeds they tend to want. Not that there aren't exceptions, of course. I've played with .177 slugs quite a bit on multiple platforms, and I'll put it like this: I wouldn't even contemplate making a .177 slug gun, unless it is capable of at least 30 fpe in .177, but preferably more. I'm not saying it can't be done with less power/speed, but most of the successful .177 slug tunes end up shooting in the 950-1050 fps range on various barrels to get the best accuracy.
-
I have the M11 in .25, IMO it will have the power and the barrel with a good polish / wax will most likely do the job in .177 many .177ammo options out there now to test with too.

Thanks for sharing your experience! The reason why I think the m11 might do well with .177 slugs is that it is capable of over 60 ft-lbs in .25 Cal. I may be off base here, again, it's why I'm asking! :D
Thanks for chiming in Back_Roads, if you could, besides .25, would YOU buy an M11 in .177? .25 is the only caliber I don't have anything in.

I have been on the edge of getting one just to find out for myself. I have a DAR in .177 lower power slug shooter great out to 100, that I have tested to. Marauder .177 that is in the 30 FPE range, feel like I'm missing one it must be a M11 LOL
Oh also have a Liberty that does well with slugs, but in-between the DAR and Mrod in power, and with out major mods will not have the plenum to push them faster accuratly.
-
I admit it, I have a rat problem, and I'm in suburbia. . .one requisite is staying a bit far away from the rats, and in order to do that my hold over and fear of misses with the .22 Cal stuff make me want a good .177.
I also have a power problem 8) my .22 Stormrider makes almost 40 ft-lbs in it's "mild" tune. The idea of a flat shooting, high power .177 for pellets/slugs over 15+ grains is VERY alluring. Does anyone know what the port arrangement is on the M11? Is there any difference between calibers? I am hoping to be able to dial it back for shooting lighter pellets and then turn it up for slugs. Maybe the asking that of the hammer spring is a bit too much?
-
That is why I have way too many airguns, easier to have one for every purpose ;)
-
If you plan on shooting rats with .177 slugs, you better make darn sure you have a good back stop or nothing behind. Those little .177 slugs penetrate like crazy! I've never even shot a squirrel with those that wasn't a complete pass through. At 30 fpe, they'll pass through a squirrel length wise, lol. I'd think I'd want a .177 that shoots HP pellets really well for the rat work. Something like Barracuda Hunters, JSB Ultrashocks, or even Terminators :D
-
Yeah I g0t passthrough @ 50 yards on possum with the DAR and NSA HP :o Bummer I do not think the ATI Nova Liberty is available any more, may find one in .177 yet, but the dual power would most likely be the ticket for you.

I completely agree! I've shot a rat with my .30@100 ft-lbs. . .yeah what a mess. I would probably just have it dialed down to shoot some of the heavier .177 pellets(at rats), and then see what it could do with the hammer spring turned up for longer range target work. Seems like the plenum on these is massive and plenty for high power, depending on factory regulator setting.

Totally agree with this one.
-
I hear ya! Not to worry, I've no interest in over penetrating rats.
I do have some interest in anyone who's built or tried building a long range .177. I read most of the threads on here about some experiences and the concept is really really cool.
-
Check out Tof's videos he did a super .177 built

Yes! And my oh my is that thing sweet. I believe he did a .172 barrel? I'm on the fence about that, as finding a barrel, and then running powder burner projectiles seems to be the way to go, but it's a lot of work, and maybe money. I would love to build/tune something that can shoot the NSA .178 slugs over 35+ ft-lbs maybe higher. That might be asking too much of the Spa m11 though?
-
Honestly I rather go with a fat .25 then a .177

I get you on that. It's a whole lot easier, but if I go .25 then I have to start the cycle of pellet collecting all over again, in a time where it seems pellets are unobtainable :-[
-
Ok, .22 then, in the end it's all about learning your holdovers or unders.
Bullpups aren't the best at that because of the scope hight, get your scope as close to the barrel as possible and the game is different
-
Yeah I may have to go .22 (I have a ton of .22) pellets. Decisions decisions.
-
I've also been interested in a .177 slug slinger :o I almost got a Hatsan Nova but ended up with the FX Maverick in .177. So far the best slug I've tested is the Daystate Howlers 12.6 gr. Still working on a tune but shooting them at 1010fps with promising results. Like Rallyshark said they do seem to be better at faster speeds!
-
The .177 slug gun has it's allure, that's for sure. Thanks for everyone that has given me their thoughts, and if anyone has more ideas or opinions, I'm all ears.

A gun shooting 18.13 jsb at 900fps with a scope height of 2.5" from bore (closer to a bullpup configuration) will have half the drop at 50 yards with a 25 yard zero than the same power and only a 1.5" scope height. Main reason you see big risers on FT guns.

Really? I would figure that the geometry would be better with a similar plane, ie lower scope. Unless you're saying that the scope will better deal with the drop because of the angle convergence, actually that makes perfect sense now that I think about it.

I see Wes has them in .22 and .25, may have to message him if there are any .177 the website seems unclear. Darn nice gun for the price.

How far are you shooting? My .177 Stormrider will push a 10.5 cpum close to 1000 fps, but only for 6 shot at the top of the curve. A good HP pellet should do the trick at that speed if you can find one that's accurate. I've done a lot of testing on the PB side and if you want expansion at low velocity, you either need a large meplat or very thin HP walls. If you can combine a large frontal area with thin walls, you get massive expansion.

I see that .177 is selectable, but yeah not sure on the actual availability.
As for how far am I shooting? I'd love to be able to stretch out to 100 yards, for target shooting, as that's about the length of my property.
Does anyone have one of these in .22? Are they also wicked powerful in .22? Like 50+ ft-lbs?

Part of it is simply because it’s a .177.
For power, the M11 would be a good choice….moving air is something they tend to do well.
No doubt that larger calibers have more energy. No doubt that the larger calibers have choices of higher BC slugs. If longest range/most power possible, the .177 won’t do that.
Won’t appeal to the “more is always better” guys….max power, highest BC is going to “win” with larger bores.
Been about 4 years. Were NOT a lot as many choices in .177 slugs, never really found the combination that shot as well as I wanted. Can get all into the barrel twist vs slug length thing….thinking I went a little too far to the heavy slug side of things.
Main test rifle back then was a .177 BAM 50...rifle was not shy about making power.
Stuff caught up to me, ended up cannibalizing the .177 BAM 50 keep a .22 BAM 51 running. So I put the project away and haven’t picked it back up.
But I saved the “top” which is a 4 screw swap.

Been kicking around the idea of trying again . Many more .177 slug choices, some of them in the lighter/shorter lengths that I’m thinking might work.
USE?
Idea was a .177 little sized pest sniper.
Needed accuracy, wanted better wind-age from a higher BC, wanted the trajectory you get with speed. Targets are little critters... energy is pretty much a by product or speed and a higher BC.
Riley:
Have an old .22 M10. “Kind of” the single shot version (suspect there were more changes than just making the M11 as a repeater).

50-60 foot pounds without any mods, just adjustments...took to slugs like a duck to water.
EDIT:
Likely the main reason I halted the .177 tests.....was just easier to get all the slug benefits and just to live with the extra energy of the .22
-
I've been really happy with the NSA 17gr .22 slugs, even at only 900fps they shoot really flat, and expansion is great. Biggest problem is how loud they are with little critters... they tend to make a POP! sound on impact.
-
Going to make me take that project up again.
Something like a 15-16gr. .177 slug, about a BC of .07, and a starting speed of about 950fps. Past tests with that weight shows the velocity is there….just didn’t have the BC then.
Not concerned about power….will have more than enough for little critters.
With a 50 yard zero, should stay on a pest bird from 0 to about 70 yards...basically a hold on the feet, hold on, and hold at the level of the head over at least 70 yards (depending on the scope height over the bore and where you sight in for zero).
Even without the energy or ultimate BC...sounds useful to me.

This was my exact original thought. It's really impressive what a 40, or even 30 ft-lb .177 does at 100 yards when the BC is .07
We're talking from 30 ft-lbs to well over 20 @ 100 yards! Can't do that with a diabolo shape.

I absolutely love shooting .177 slugs! They have a lot going for them. You get deceptively quiet power and penetration with them, lower air usage, and they are also great for long range shots. The absolute hardest part about a .177 slug gun isn't the power, it's the barrel. Finding a barrel that truly does well with .177 slugs is the hardest part. Sure, finding a barrel that does "okay" isn't that hard. Finding a barrel that is same hole accurate with .177 slugs is a whole other ball game. It really is hit or miss in that department.
If you manage to get a gun/barrel combo that works, chances are you'll never want to get rid of that gun ;)
-
I just ordered some 10 and 11 grain from Griffin. My Stormrider should push them close to 1000. Can't wait to see how they do.
-
anyone ever try the M11 177 with slugs? I'm making an order of NSA Slugs to sell on my website and if these NSA slugs do well in the 177 I'll up my order of 177 slugs. :D
-
I haven't tried them in those barrels, so I'm afraid I'm useless there. I think your best route would just be to try them and see how they do.

Will do! Once I get the slugs.

I ran some NSA 12.5 gr slugs through mine, so far so good, also shot some of my home cast 11.8 gr. in tin but only @ 10m during crony test so far. NSA had no problem at 50 yards to date.
-
Have not collected it all into something post able...was a very limited test. Grateful for the limited number of donated slugs (12.5gr. NSA HP/HB slugs).
Did try that old BAM 50/51 mix...several posts back there is a pictture.….the .177 upper on the .22 lower mentioned some posts back.
ZERO time/effort tuning adjusting...just slapped the .177 upper on the .22 lower.
Honestly didn’t think they’d work.
I was wrong...not a universal endorsement, but in this standard issue barrel they did work well.
Could have tuned the old rifle up a lot hotter, but cruising along at 915fps seems to work just fine. 23 foot pounds in .177...slap the .22 upper on and it’s more like 32 foot pounds with it’s favored pellet...seems about what to expect.
----------------
Still debating why I want to. Great for uses I don’t have. For the uses I do have, thinking .22 and pellets would do it.
--------------------
Thinking about the older .177 tests….got greedy in the old tests and went with too long/heavy a slug and suffered some stability issues.
-
This thread kind of faded away, and I never did pick up a .177 M11, but if WesBob says slugs perform well. . .I might just have to do that. Thanks for all the contribution, as well as thread revival. Sounds like they do well @50 yeards, which should be a good sign for longer ranges.
-
From what I can tell with calipers these barrels aren't choked. Might be my poor measuring skills but I could not get a smaller reading at the muzzle on the different barrels I checked.
-
I have very limited experience with .177 slugs and none with the M11.
I tried one gun with 12.5gr NSA's, pushing them around 800fps. They didn't fair very well. That gun did great with pellets so I didn't want to mess with it. With a different gun (BT65) I tried the NSA 15gr slugs. They did much better. Non regulated and the hammer spring turned down, I was getting an average of 995fps or so (~33fpe). While sighting in at 25 yards, those slugs were zipping through a 2X10 board I usually use as a target board and into the tree behind. Moving to 50yards with two fresh 2X10 boards, one ahead of another and with a berm behind I thought I was good for a bit. What surprised me was they were still zipping through the first board. I have a box of NSA 20.5gr .177 slugs that I planned on testing with the hammer spring cranked up. Honestly don't know what to expect from those. Haven't tried the NSA 12.5's in the BT65 as I didn't want to push supersonic speeds.
Once I hit ~25fpe in .177 with pellets I was amazed on what they could do. Getting a 30fpe+ pcp that did well with slugs brings it to a whole new level.
