I just bought a Lee Collet die for my .30-06. I was putting together some 185 VLDs and I had some brass I had resized with my RCBS dies and I had some brass I sized using my new Lee die. What I noticed is the brass resized with the RCBS was a lot tighter. The VLDs felt like they were falling into the brass I sized with the Lee Collet die. That doesn't bother me when I am going to the range but, when I am hunting in the field if need to take a second shot is my OAL going to change with recoil??
