[QUOTE="scottyd2506, post: 823209, member: 19778"] Why not? The 4040 fps with a 39-40 grain bullet is not normal for a 204 in any bbl length. I was fairly happy with the loads, getting less than 1/2 moa groups.. But the excessive fps raised a Red flag.. I THOUGHT I had my scale zeroed, but I was off. and zero'ed it with 1/10th grain, leading to a grain over max in a 204/223 sized case. What I thought was 27.4 of 8208 was 28.3 of 8208. 1 grain over max in most 204/223 cases is another 200 fps Once I reset my scales. the actual 27.4 grain load of 8208 was 3854 fps.. my next 20 I loaded at 27.3 should get me close to 3825 fps depending on temp. I'm happy with this speed at SAFE pressures. with the 27.4 grain loads and pulled bullets, I shot a few 3 shot groups of 0.540 inch, 0.520 inch, one 0.375 inch group and a 0.095 inch 3 shot group or sub 1/10th of an inch. last week I shot a 0.19 inch 3 shot group and some 3/8 and 1/2 inch groups.. They are only 3 shot groups, not 5, so I really can't brag.. but It is good for me and poor shooting, bad eye's etc [/QUOTE]
