Tuning Maverick hammer/pressure question

Thach2264 · May 17, 2022

Can a 11g hammer on a Maverick fully open the second reg at 135b? I’m asking this because I’m trying to tune my .22 with 600mm barrel to shoot KO 25.4g and NSA 24.8g.

KO with power at 7 and micro screw @ 6.5mm out. Max I get is 940ish fps

NSA pw@5 I get 940ish fps

I’m asking this because AEAC got 34g going at 945ish with 125b at pw7 and ihs at -2.25=2.25mm out

I’m at 135b pw7 and ihs -6.5 and can barely break 950ish with 25.4g KO. not sure if 34g pellet is easier to fly hotter than slug.

thanks

I believe Matt duber and also AVS slugs company have both said in videos that slugs do have more friction in the barrel then pellets and take just slightly more power to move at the same speed at a similar pellet weight. I have experienced this with 34gr FX pellets and 32 grain AVS slugs. They travel about the same speed with same pressure, even with the slug being slightly lighter.

910 airguns has a video on this very subject.

So send him this question. he will respond to you. Newman is really good people. Typical FX customer service.

After battling tuning I came across this post

Look at the #3 tune of bunkeru2k’s first post.

your 2nd reg pressure and hammer weight may need slight change due to your shorter barrel but that should get you close.

I play with it the other day and got this, look pretty close to bunkeru2k

150/135 600mm with hst 6mm or 8 1/4 ccw

JSB KO @7 955

NSA 24.8 @7 945

JSB 18.1 @4 990

JSB 18.1 @3 925

i'm happy or....maybe should up the 2nd reg to 140b.
