Thread: .22TCM Micro Varmint rifle build

A little more midnight oil burnt and I got the Shilen barrel threaded for a suppressor and loaded some more test loads.
This time I loaded on once fired brass and use CCI BR-4 primers to see if there was any change in the extreme spreads. I also backed off the H110 charge from 13gr at 3180fps to 12.5gr at 3050fps which matched the Lilgun pressures and velocities a bit better.

I loaded both 12.5gr of H110 and 10gr of LilGun with 40gr Sierra Blitzkings and put them on paper at 100y.

I still have the 7x VX1 mounted as my picatinny rail adaptor still hasnt arrived from USA to fit some bigger glass. There was also a bit of wind from right to left which resulted in some slight horozontal stringing but still some respectfull groups.

The extreme spreads were better but still nothing to write home about...

H110 : 3015 3030 3051 3042 3059



LilGun : 3034 3069 3028 3081 3042



My Alliant 300MP arrived today and also some Hornady 40gr BT V-Max projectiles so Ill try and make time tomorrow to test that too.

The suppressor made for much quieter shooting, about the same report as a .22 magnum.
I also made up a blind fit thread protector to keep it looking tidy.
