Range day today.
Loaded up a box of 22g 4227/180g SSP RE-sized to .356. Fired some @ 100.
100 yard shooting, Left group; Is the results. First two shots are 1.5" high mostly centered... Third shot was 5.5" lower and 1.5" to right... Fourth shot was back "up" 2" below first shots. Fifth show was not found.
Right pattern is shot with Factory 145g ammo. Its a 3x6" pattern...
Then I tried a few SUB loads.
THEY IMPACTED 6" HIGH @ 50 yards. Trouble is... My RUGER BOLT. Shoots SAME ammo 4.5" LOW at same Distance. I then tried the new Sarco Bullet loaded on top of 10g of Herco. Its a super Sonic loading. I didnt chrono, but estimate the velocity at 1300 fps. It also shot HIGH! Above and off the target.
I moved the 22g load back to 50 yards. Last time it shot touching holes. NOPE... 3" group!
I took all these loads and fired them from the Bolt.
I tried Factory 145 & 180 G Winchesters and all seem to shoot as erratically.
I can only assume my first assumption. Barrel whip. This barrel has problems. Im gonna see if Faxon can do anything about the barrel they made.
