Thanks for the info gents. I started into reloading with my .45-70 and use a Lee factory crimp with good results as most of the info I found indicated the45-70 should be crimped. Then I started loading for my 243W and 300WSM and haven't been crimping them b/c it didn't seem that common in these caliber/gun (bolt) combos. Just wanted to see if I was missing something.
On an unrelated mattter (yeah, that's right, I'm hijaking my own thread) do you guys recall your first big game animal taken with a reload? I have killed quite a few big game animals, but this will be the first year I will be hunting with ammo I loaded myself and I'm getting pretty excited about the prospect of dropping something with the home-rolls
