So excuse my ignorance guys but i need some help. I was told a 1-8 twist was slower than a 1-11 so i could run heavies out of my 300wsm. I loaded up on 210s and 208s. They havent shot like i was hoping, they do shoot 1/2 moa at 100 but drift a bit at 500. I actually thought about it for a fewe minutes tonight and thought to myself, wait a minute 1-8 is faster than a 1-11 and my bergers say they are best in a 1-11 for the 210s. With my 1-8 twist being 28" long is there a weight you guys could recommend?
