I did a quick search and couldn't find the answer. If its been discused please advise. I've been going over balistic calcs, and this seems like it would make a sweet long range round for me. My current 300WM has 24" factory tube. I know I wouldn't get 2900fps out of it. Is it even possible to get that speed out of a 300WM with the 220gr? If I rebarrel would a 1 in 10 twist be ideal for the 220gr? Any experience you've had with this cartrige and bullet combo would be appreciated. Thanks in advance.
