"Special" new .177 barrels!

[Rallyshark]

lot of rifling buttons for sale by those guys, are they pushed through the barrel from the breech ?
dont see any attachment on the buttons.

I saw that too.  I've no idea on how those particular ones are meant to be used.  I think I'll stick to barrels made by proper barrel manufacturers myself

I got the barrel sleeved now, and everything should be ready for sight in!  Now I just need my ammo to show up, better weather, and some daylight to see what she's gonna do...  If the barrel is a winner, then it will get it's camo to go with the rest of the gun   Here's a couple of pictures.  One without the big 'ol LDC, and one with it.  The phone distorts things, but it will actually fit in the case with the LDC attached.

Buttons are brazed  or silver soldered onto a steel rod. Either pulled or pushed thru the bbl. Small cal.. require pull thru due to flex id pushed.

I got to do a little testing yesterday with the new 14.6" twist barrel, and the results are pretty good!  I wasn't having a good shooting day, so I'm not going to post any groups at the moment.  I did know when I pulled a shot though, and the barrel did consistently well with the Griffin 23 and 24 grain slugs.  Most groups were a little under 1/2" with them at 30 yards, and the NSA 20.5 grain.  I think with a little more time to find their happiest speeds they would work very well.  This barrel shot all of those heavy slugs better than any barrel I've tried.  I need to do some testing at a longer distance too.  I think I'm going to regulate it, and change out the hammer spring, so I can do some testing with the 15 grain slugs next.  That is the tune it will live at most of the time anyway. 

On a side note, I managed a peak power of 58 fpe with the 24 grain .177 slugs!

This is great!! Was gonna ask today to see if any updates.

Looks promising.  58fpe in .177 is amazing.

I think there's a lot of promise with this barrel.  I just need more time to play with the speeds a bit.  I'm also going to try it without the front barrel band on there, because I think that has me chasing my tail a little.  I finally figured out today that it had shifted some.  I hope to have some definitive results in the next week or two, when I can get some more time to play with it.  Here's a 5 shot group I did earlier today with the 23 grain slugs.  I choked and yanked the last shot,lol.

It is pretty awesome, but it can't hold that power for long.  The highest power realistic power tune is around 53-55 fpe for one magazine.  This is a case where a bottle gun would open up a whole lot of possibilities, as would the ability to do a higher fill pressure.

Forgot the group...

Oh wow!! Definitely looks promising. I’m considering one for my Origin, cause I really like the feel of the gun but just not sure if i could get enough power out it Or I could just get me a Flash & have you machine the barrel for me. 😉😉😉

I would think the Origin could be ported and tuned for more power, but I don't know anything about those.  Those Airforce guns would be good slug candidates!  I mean, they have power to spare.  I'll be the first to say, I don't know if the Flash is the gun for everyone.  They take A LOT of work to get up to those power levels.  There are many other guns that would probably be easier to make that power with.  I don't machine barrels for other people.  It's one thing to mess up my own stuff, but I'd feel horrible if I got someone else's barrel wrong!  My machining skills are just enough to get me in trouble

Yeah I had my Origin apart & seen some stuff that needed attention but I really wasn’t worried about power till I thought about this barrel for it. I did drill the barrel port out but that was it. I know the transfer port through the receiver needs attention it’s kinda small & it’s threaded which would cause turbulence. Right now with the hammer spring turned in 4 turns it’s getting 885 with 22.5hr VK’s. So I’ll be tearing back into it to see what I could do it to get it a little more power out of it.

I was messing around about the barrel, my cousin builds custom PB’s so he could do the barrel for me.

The jury is still out on the 14.6" twist Alfa Precision barrel.  I'm having a hard time nailing down what works with the lighter slugs at the moment, but I'm also thinking it is time for a regulator rebuild.  I'll get back to the light weight testing in a week or two.  I have some other stuff I have to take care of first.  At the moment, I can only say it works with heavier 20.5 grain slugs and up for sure in .177.  I was also shooting those without the regulator installed, so...  I need to remove some variables and try it again, so give me a few days and bear with me

I have a small update.  I machined the 16.5" twist Alfa Precision barrel, and it's a laser with the 15 grain NSAs!!  This barrel is shooting those better than any barrel I've tried.  I honestly couldn't expect anything better.  It appears to be the perfect match.  I got to do some proper long range testing Sunday.  At 30 yards, they were one ragged hole.  They shot very well at long range too.  I watched them in flight well past 100 yards, and there was zero wobble, and they were dead on.  I was popping pieces of gravel off a gate at 110 yards, and they were not missing at all!  I even managed to pop an egg at 150 yards   Cans at that distance weren't even a challenge.  I'm speaking specifically about the newer 15 grain from the high speed machine.  I was shooting them at 1000 fps on the dot.  That was regulated, and it yielded a very good shot count for me too. 

I've tested them previously in LW polygon choked, LW polygon unchoked, LW standard chocked, LW standard unchoked, and Hatsan.  I had good results with the unchoked polygon LW with the older 15.5 grain, but haven't been able to get the newer .178 15 grain to do quite as well.  The short version is, if you want to shoot the NSA 15 grain in .177, the Alfa Precision polygon barrel is the most certainly the barrel I would use, if possible.  The LW standard rifling barrels in choked and unchoked do well too, but not as well as this AP barrel is doing.  Not in my testing at least. 

I haven't tested the other weight slugs in the 16.5" twist barrel yet.  I was having too much fun with the 15 grain, haha.  I hope to do some more testing in the coming weeks with the 12.5, and some heavier Griffin slugs in 23/24 grain.  I just wanted to give a quick update, since I know the 15 grain slugs are the ones most people will be shooting.  If you got a .177 slug build on your mind, give Brian at Edgun West a ring, or even email Maxim at Alfa Precision, and see about getting that polygon on the way!

WAY TO GO DONNY! Good news man...

Thanks!  I'm super happy about this one   I've been trying to nail down the new .178 slugs for a while now, and I could only get them to do "pretty good", so I'm stoked that AP barrel is shooting real good!  Their 14.6" twist barrel does great with the heavy stuff, but too much twist it seems for the light ones...
