[QUOTE="Deleted member 46119, post: 906159"] The last thing I can think of is to slug the bore. AIUI (AS I Understand It) If it is tight or a tight muzzle end that would mean friction which would mean pressure but lower velocity. I run my target 300 RUM with 210 VLDs at 3063, I tried faster but it got me nothing for accuracy and wasted cases. I forget the dimensions but I'm sure the neck it is tighter than yours but I turn to .014. 86.5 of H1000 SD=4 ES=11. I'm silly but I carry a bit if paper I punched with 4 holes at 300 yards, around 1/2 inch. I didn't have a 5th round. I did not build this rifle, I got it off Accurate Shooter forum. [/QUOTE]
