Brocock/BRK Brocock Sniper HR .25 got a Power Tune from AOA

With some help from @Sleeve28 I had been trying to tune my Sniper HR to get some more FPS and FT-LB out of it, I also had reached out to AOA to get advice from them as well.
I managed to get it up to 901 FPS with 61.3 FT-LB with a 33.95 JSB pellet. I was also looking at maybe trading in the gun for the new 30 cal. Sonoran as they do a power tune that includes a new bottle and really jumps up the speed and FT-LB on that gun, then I thought why can't the power tune be done on my 25 cal. so I called AOA and talked to Shane in the service department and he said they had done a shop .25 and it was shooting a solid 960 to 970 ay 68 to 70 FT-LB, I asked about doing my gun and he said to send it down, so I took it apart and sent the action with the gauges to them and they got it shooting the same vas the shop gun and sent it back to me. Today I went and shot it and was getting 944.2 average after 33 shots with and average of 69.1 FT-LB, I was happy with that! I live in Washinton so guessing the difference from Arizona to here would affect the speed a little.
So if you own a Sniper HR in .22 or .25 and you want some better performance you should call Shane at AOA and get the Power Tune done!
I had a 700 CC bottle already and was into to it for $212! including shipping both ways.
Out of the box I was getting on the crono on with the dial on high power I was getting 862.7 FPS and 56.2 FT-LB with the 33.95 Pellet.
Next thing that I am waiting for is SUB-MOA to build a .25 cal. barrel, Shane called, and they told him 6 to 9 months and they should be making some!!

Happy shooting
 
@duchunter007 How’s the cocking on your Bantam Sniper HR after their tune?
Funny that you ask, as I was expecting it to be firmer than it is, just a little more tension but still nice and smooth!
I only shot it a few times and it was windy and heck and then started to rain looking, the wind stopped just long enough to get a quick sight-in and then I was able to shoot a nice 5 shot dime size group at 50 yards,
 
Hmmmm...

Extrapolating from that information I'd guess they could pump my 14.5" barreled .22 Sniper XR pistol/carbine convertible up near 35 foot pounds. :unsure:

On second thought, since I use her mostly for Extreme Pistol Field Target competition on power-level 2 due to the 20 FP power limit, Black Betty is perfect as-is. Matter of fact after doing the convertible work I had to reduce reg pressure to find 19.99901 foot pounds on PL2; that dropped PL4 from 30 to 28 FP.

I really, REALLY love my .22 Sniper XR; however she required a (warranty) barrel replacement by AoA. I then did a LOT of tuning and tweaking, both before and after the pistol/carnbine conversion. All the details are in the attachment.


Three consecutive five-shot groups at 100 yards on power-level 3 (pre-conversion)-
