[QUOTE="davewilson, post: 159560, member: 4491"] 50, not sure what twist you need for these bullets,i'm sure that's part of the research in progress. but i would guess even though the bullets are fairly long, you're probably spinning them a bit faster than necessary. if so this puts the bullet in a nose up condition and affects the BC until it slows down enough to let it point in the same direction that it's going.this would fall into the different BC situation which has already been mentioned. also i think you've fired way too few rounds to accurately say where the POI is at given ranges.how about a 5-10 shot group on paper to have a more accurate idea for POI. you could always look up trigger 50 and send some through the doppler radar.i'd let you use mine but i can't seem to find it as i'm finishing the one side of the basement.
