6BRA - suppressor barrel length

[shaun1826]

Anybody done a shorter barrel length on a 6br cartridge for suppressor? I’m going to have an Impact prefit done for PRS use with a suppressor and am curious if anyone has a 26-28” barrel and also the same barrel done in around a 22-24” barrel for suppressor use and could tell me the velocity difference between the two. I’ve seen some articles that give approximate velocity loss per inch but would like some real world numbers before I decide to go shorter than 26”.
Thanks,

24" 6BR gives me 2,860 fps with RL15 and 105 gr Hybrids wearing my TBAC Ultra 9.

22” Dasher 2900 with 105s and 2880 with 110s , so really close to that with a BRA
Which is probably already faster than most in PRS. I like 109s 2800 myself
