[QUOTE="nodakhunter, post: 2599864, member: 111782"] I built this rifle primarily to be a hunting rifle and am using a CIP detachable mag. So I’m limited to 3.75” OAL if I want to mag feed, which would be preferable. Pic included is where that bullet is seated at max mag length. The gun also had a +P throat cut. When I got the rifle back, I loaded rounds at max mag length with RL33 at a few different charge weights. It shot a couple of groups around .5 MOA at 95.6 grains, but it was erratic. One group would be .5 MOA, the next 1.5. This charge gave me a velocity of just over 3000 fps with no noticeable bolt lift or other signs of pressure, but I wanted to see if it could do better. Shot various charge weights from 93-95 grains earlier this week, and the 93.0 grain load produced several sub-0.5 MOA groups @100 yards. Took it to 1000 and saw very little vertical spread which I had struggled with at the higher charge weights. Planning on doing further testing at around 93 grains. Rifle info: BAT HR, Helix 6 27” 1:8 twist barrel, Game Warden stock, Bix n Andy trigger Edit: Do NOT use my load data in your rifle! This gun does not have a standard throat! [/QUOTE]
