I can see absolutely no reason not to have several of each and a couple 7X57s too..........and a couple 6.5s and a few............well you get the idea.
It's a must if you want to have a complete set.![]()
Nope... the complete set of RSI's would be .243, .257, 270, 7X57 & .30/06...
If you look at the ballistics for .243 and .257 Bob, you will see that the Bob just barely bests the .243... not enough for me to make the Bob a priority... for now.
