Hello All.Just got my crimper from Wholesale sports and used it on my .444 reloads.First time using on of these devices.How heavy of a crimp is needed? I just adjusted it so the edge of the brass was rounded in the canulare of the Hornady bullets.Tried pushing the bullets in on the bench but they held fast.Didn't need much pressure with Mr Rockchucker to crimp.Also is it worth it for doing 30-30 rounds or just stick with the RCBS crimp in the die?Thanks.
