If you are going to quote me and roll on the floor laughing your arse off then have the common courtesy and not take it out of context. I stand 100% behind that statement.
If he isn't at the range practicing weekly then the point of having a 30-378 is pretty much gone. Any regular ole 300 magnum or 30-06 will do everything the 30-378 will.
I haven't rebarrelled any. Down here in Alabama there are very few people that have any need what so ever for a 30-378 and the ones that do actually have one never go to the range and practice with them enough to take advantage of the cartridges ability. In fact these rich, gotta have the biggest and baddest, mine is better than yours kind of people that I am refering to don't even sight their own guns in. They pay us to do it for them. Then they go on a $10,000 elk hunt and come back bitching cause they missed an elk at 600 yards and tell us it's our fault.
You don't have to rebarrel a gun to know what happens inside the bore when you pull the trigger.
