Here are a few groups from my RAG2 ranch 22 ARC. I installed a timney trigger and am shooting suppressed. The pic rail was removed, degreased, and torqued to ~65 in lbs. Warne mountain tech scope rings 65in lbs at the base, 22 on the scope. Using a swfa 3-15 gen 2.
The new trigger made a huge difference. I first used the suppressor at the same time as getting a better rear rest so I’m unsure how much each contributed to better groups, but both factors helped.
The load is: 77 tmk, 29 grains staball match, peterson brass, coal 2.210, lands at 2.217, cci400 primers.
Velocity is uknown, I’m guessing around 2800 as sierra load data lists 3000 with 29.1 grains of staball match, so i estimated a reduction of 50fps for every 2” of barrel.
29.5 grains resulted in 2 ejector marks after 7 shots. One shot of 30 grains resulted in a cratered primer. 29 grains has had no signs of pressure (book max is 30.3).
It is a very fun gun. I may try to remove some surfaces as CoMtnMike mentioned. I also plan to follow a diy stock mod from BLJ.
Group 1 (ignore the 6CM 7 shot group).
Group 2
