I’m putting together a pair of varmint rifles for myself and a friend, with the idea of targeting 500+ yard coyotes, groundhogs, & steel targets. We will probably be doing a lot of shooting so I have decided to just buy a reamer and hold onto it for future barrel changes. I haven’t reloaded for any cartridges with 40* shoulders before, but I hear they can be somewhat troublesome at times, and since QuickLoad predicts the 22-250AI will have some extra capacity with my bullet/powder of choice anyway, I was thinking of just having the reamer made with Slightly more taper in the body and a 35* shoulder. (The result should still have substantially more capacity than the standard 22-250) Anyway; My Real Question – Would the same chamber reamer work to make a 6.5 X 22-250 Improved ? I’ve had the urge to try something like a 6.5x47 Lapua for a while now and my proposed version of the 22-250 improved should be nearly identical (with just 5* steeper shoulder) I am just looking for a way to save money, so if the same chamber reamer works that’s one whole reamers worth of funds to put toward barrels, and I already have More than enough Lapua brand 22-250 brass on hand to feed both rifles indefinetly.
