Tuning Impact m3 tuning for 23g h&n slugs .22

[sanjay n]

Hello every one need help for tuning my m3 with 700mm barrel for H&N 23grain slugs
Can any one give the exact reg pressures and micro and macro wheel number

Thanks in advance

I'm shooting 23 gr slugs in my M3. Reg 1 is 155, reg 2 is 130, Macro wheel is 9 and micro 4. Velocity is 950. However, I must say that my rifle shoots FX Hybrids better.

I'm no expert and would start with a lower regulator setting like 80 bar. Set the Micro at 3.0. Increase pressure until you reach desired FPS. For the record, my 600 mm is 90 bar and 3 Micro shooting 22 gr RMRs at 860 FPS.
