A.E.A. the gun of the moment ?

Range on Y axis  is much greater I just realized - that will make it look flat

Good point.  I've expanded the y-axis to show the variation more clearly.  If my calculations are correct, a variation of 60 fps would result in a POI change of approximately 5 inches at 200 yds.  A variation of 30 fps would result in a POI change of approximately 2 1/2 inches.  Give or take a bit.

If you are hunting or shooting long range I would air it up to whatever pressure you had at shot 13 and shoot only ten shots. I would guess the fluctuations in that range are probably temperature related, the cylinder temperature affects pressure and shooting quickly creates more variation in the cylinder temp.

My target velocity was 1,000 fps so 1050 fps is a bit hotter than I was going for.  I'm going to shoot another string with the transfer port closed a bit.  I'm hoping that will flatten the curve a bit more and give me more shots per fill.

FWIW I'm not hunting, just target shooting long range.  I have targets set up at 135 , 195 yds and the room to shoot even further.

     I ended up turning mine down to 1:00.  I have the .25 backpacker in .25 shooting 25.4 grn pellets.  I have 30 shots now between 920 and 895.  with a highest velocities after about 10 shots.  Prior with it turned up I had a straight decline starting around 955.

     Wayne is shooting slugs in his and I just received some from FX to try.  Haaven't tried casting slugs yet but I see it coming.  With your velocities and desire to shoot longer ranges slugs would benifit you too.  I would think most people who buy these rifles are plinkers or hunters.

I'm shooting H&N 25 grain slugs.  I just refilled my tank to 3,500 psi and set the transfer port to 11 o'clock (same as your 1 o'clock).  If I get two magazines (24 shots) at 1,000 fps I'll be happy, but I'd be even happier with 30 shots!

My Cayden .22 -loves- the FX Hybrids.  I haven't chrony'd it yet but I was hitting my 4" gong at 135 yards and never missed a shot.

I guess I'm a long range plinker.  I keep saying I'll compete but the nearest events are usually 10+ hours away and I have the perfect location for shooting right here at home so I end up not going.  So I guess that makes me a lazy long range plinker. 

[Captain Paul]

I shot another string over the chrony.  This time I set the transfer port at 11 o'clock and filled to 3,500 psi.  My goal as 2 magazines (24 shots) with H&N 25 grain slugs at 1,000 fps..  Looks like I'm there.

Received a DonnyFL adapter but it is a weird one.  The bore is oversized (0.5” I think) and as a result none of the ldc’s or adapters I have will work with it.  I’m not sure I understand what the point of this adapter is if it doesn’t actually fit standard products.  I need an adapter for my adapter. 

[Captain Paul]

I shot 3 full magazines (36 rounds, .22 H&N 25 grain slugs) at 50 yds, light wind.  This is my best group.  Not stellar, not single hole but considering the crappy trigger and sloppy stock it's not horrible.  I think if I clean up the trigger some more and get rid of the slop in the stock I can cut the group size in half.

I would be calling or emailing to see if you go the right part. They were quick to get back to me with questions.

     Yeah the trigger is the big wart for this gun.  Magazines I can live with but the trigger needs looked at.  Accuracy though is stellar.  I'm hard pressed to think of a stock 22 lr semi-auto that shoot this good out of the box.  I discussed the velocity stats with Bin and he stated most guys with the carbines refill after two mags.  If I was shooting beyond 50 yrds that is what I would do.

Which model did you get in .22 ?  I was going to convert my HP 25 cal semi carbine with the varmint barrel kit, instead for another $150 bought the Challenger LS .22 and glad that I did because it's shooting my cast NOE 218-25-RF slugs extremely well, I've never been into bench shooting but the gun sure makes an excellent hunter, I plan on shooting ground hogs at a distance in the bean fields at the state land that I hunt with it.  Also would like to get a coyote in my sights as well.

     My adapter screws into the end of the shroud then my Sumo or Tanto screwed right on.  I ordered my gun with the 12 inch shroud and adapter not getting their LDC.  Here is what mine looks like.

I got the AEA HP Varmint in .22.

Today I polished the trigger (so now it's polished and has lighter springs) and turned the transfer port to about 11:30 (a bit hotter than yesterday).  I think I've got the trigger to as good as it's going to get.  It breaks clean and crisp, but the pull is heavier and longer than I'd want for competitive target shooting.  We had a front pass through this morning so the wind was blowing pretty good, maybe 5-20 mph and from my 8 o'clock.  Here's my best 5 shot group at 50 yds with H&N 25 grain slugs. I also tried some FX 22 grain hybrids which didn't do any better (and some were going super sonic).

Next up is to polish the bore.

[Captain Paul]

Well, I sent back the HP Varmint.  It seems that the better the weather got the worse the gun would shoot.  Bin seems to think there's an issue with the barrel.  It had a burr in the crown that I polished out but maybe there was something else I didn't see.  Sooo...  I sent it back and ordered an AEA Challenger Pro.  The biggest thing I didn't like about the Varmint (besides the accuracy going down the tubes) was the bolt and the Challenger Pro is a side lever with lots of power as well as being regulated.  Hopefully it shoots lights out. 

[Wayne52]

Just by being used to Evanix magazines and now using the JTS magazines I'm blown away at why companies still stay with the crappy Marauder style mags

You can bet it’s about $$$. They probably use the Marauder mags because they can do so without paying anyone for the rights to use the design, and don’t have to shell out for R & D to
design something better.

Did you get it from Bin at the Pelletshop.com, or the other Bin?

Have you got it yet, and did I miss the post?  How do you like the side lever?  I'm sure it's much better than the bolt action.  I haven't looked at the price difference.  Any other differences other than the side lever?  Any improvement in the trigger?  Keep thinking about getting a varmint for pesting but the Carbine is meeting my accuracy requirements for now.

[Mr.P]

Got some iron sights and cooked up a sleeve with Picatinny rail that I can print and slide over the end of the shroud. A FedEx driver is out there with my Hp max, supposed to be dropped off some time later today.  I am ready… got a bunch of roundball thanks to manny’s tip, an extended shroud with metal cup baffles from Bin Tac and a screw on moderator from Rocker1 that I am printing some 357 baffles for.  Ordered several tins of jsb 81ms from trenier a while back but they must have been stolen from my mailbox because I never saw the package.   I can order another set of the JSB’s but I just hate spending that much money on pellets it’s like throwing good money after bad I guess and will just have to do some casting.  I can order a mold for the price of reordering these on top of the ash order.

I’ll see what I can do with round balls and my own bullets though I am sure  the accuracy won’t compare well with the JSBs.

Got it last week, look for my thread "My first 48 hours with the Challenger Pro".  The side lever is a huge improvement over the bolt action.  It was $200 more expensive than the Varmint.  Other differences:  it is regulated, max bottle pressure is 4,500 psi, completely different design than the HP series.  Trigger is much better, about on par with the HP after swapping springs and polishing the contact surfaces.

I've started going back to open sights for my powder burners.  Both my AR's are set up like my service M-16.  Sadly, none of my air rifles have open sights.

When I see all the cool things you guys create with 3D printers I get tempted to give it a try.  What software are you using to design and what printer?

Thanks, I know I was reading that thread when it first started.  Should have made a comment to stay posted on what was going on.  I'll go back and re-read it.
