[QUOTE="Kevin, post: 25928, member: 603"] Hi, I have a 22-250 AI in 14 twist, it likes anything 55 and under. If you want to stay with the higher velocity approach, as I did. 50-55 gr bullets will be your best bet. Anything less has a very low BC. and the wind drift becomes large. I would suggest a 52gr. A-max. Out of a 26in barrel you can get around 4050fps. This load yeilds very good trajectory out to 500yards, and wind drift isn't bad. PD's out to 400 are almost a gimmy but 4-500 gets a little trickier. If most of your shots will be from the 4-500yard range. You may want to go with a 9 twist and shoot the 69-75gr bullets. Initial velocity will be significantly lower but the BC wins in the long run and wind drift at 500 yards is decreased by 5 inches considering a 10mph wind, bullet velocity is actually higher at 500 yards, energy is about 30% greater, and there is not much sacrifice in trajectory. Hope this helps [/QUOTE]
