Did some load development today for the 308. Not sure but think my chrony might be on crack? Anyways gun needed sighted in. So I used some blackhills match 175 smk that have shot well in past. Well 3 shots later I was zeroed at 100. I shot these three through the chrony and averaged 2680. Then I started with my loads of cfe 223 with 175 smk's loaded to same length as the factory stuff. Started at 46 grains and went to 48 in .5 grain intervals. 47.5 is max. Well all these loads were couple hundred faster then the blackhills. 47.5 and 48 proved best groups. With 47.5 I averaged 3055 fps and 3089 with 47.5. This seams really high to me? Starting load was in upper 2800's. I kept the chrony in the shadows never moved it and was sunny out whole time. Also the cfe 223 has a different smell for sure. Gun is a savage mod 12 bvss 26" tube.
