I recently picked up a 300 win mag TC Venture and I believe I will now do a 7mm-300 wm on a spare action for long range prairie dogs. My questions concern the belt. I have never messed with belted mags. I have read the cases will expand ahead of the belt requiring a special body die to resize. If so what is the best die for this? Could or would a 300wm small base die resize this area of the brass?
Thanks!
