some brocock bantam hr numbers

[rangur1]

played with my brocock bantam sniper hr 25 cal. shot jsb 25g pellets. i did not shoot a ton because i was pressed for time when i did it. but here they are.

setting 6 high-845,835,838,838,835,836,839,843,834,838--fps spread 11, ave 838 fps FPE 39

setting 5 841,838,839,837,846,835, 834, 832 ,837,836 -- fps spread 9? ave 837 FPE 39

setting 4 824,823,822,821,822,816,819,815, 812, 818 -- fps spread 12 ave 819 FPE 37

i did all shooting with a donnyfl shogun moderator attached. not sure how much it affects velocity of pellet, but i figured i would mention it.

838 FPS is the max speed you can get? I was expecting to see at least on the lower 900s with the 25g kings :/

i have not tuned the gun at all, i bought it second hand, and i will shoot more thorough with mod off. might make a difference. who knows?

 

[Bob_O]

Suppressor should not affect velocity......POI maybe.

 

[Renegade_626]

how many shots per fills does it get in .25 caliber? how do you like this gun so far? accurate? any issues with it?

This is what I got on my bantam sniper hr .25 with a donnyfl shogun attached. 

 

[rangur1]

gets a lot of shots , have not run a full load but at least 60+ , and i'm thinking closer to 75. it's been cold, and i have been crazy busy. accuracy seems spot on with several pellets, but i have yet to have long shoot session.

That's a nice ES!!

What's your reg pressure? Should be able to get 50fps more easily if you wanted.

just thought of that, mine is reading 140, prior owner might have tuned it down a touch. he used gun for pesting collared doves and starlings from his truck. maybe wanted to maximize his shot count?

 

[Bob_O]

Sounds about right for that velocity.

 

[Kaeokini]

My reg pressure shows 150 but its weird because when I refill the tank the reg pressure always shows a little higher than 150, about 160ish and that's filling the tank to 230 bar. After 4 or 5 shots then the reg pressure reads 150. 

 

[Bob_O]

My Crown always reads about 5 bar higher after refilling. It drops to the set pressure after one or two shots.

Looks good and consistent like I remember it being. I don’t recall if I ran it across my chrony but I for sure didn’t adjust anything on it. I got it from AOA set up just as it is, threw my Aztec on top and terrorized the local ground squirrels with it. I think bumping up that reg will give you a little more for sure. I’m glad you are enjoying it, my Impact just went flat (sprung a leak) again... grrrr, more time on the parts bench and not the shooting bench. I am trying to set it up to slay starlings at night. I am up to 750 shot with my Streamline but man, loading the mags and refilling the gun are slowing me down for sure! Maybe I’ll have to look at a Crown like Bob_O did. Oh well, have a great day!
