[QUOTE="Patriot007, post: 1912577, member: 111276"] May I suggest, just use your Redding die to bump the shoulder back .002 and get you a lee collect die to size the case neck. I not familiar with the Redding bushing die but I am with the Forster bump die. With the Forster bushing bump die. I found that using the bushings to size the neck was a pain in the butt to get .0002 case neck run out. It required 3 different bushings to work the case neck down to .0002 run out." along drawn out process." The Lee collect die solved this problem for me. The trick for me was tuning the case neck for grip tension. I solved that by ordering a Blank drill bit. "For 223 rem - .221 plus and 6.5CM - .262 minus. With these blank drill blanks I am able to adjust my Lee Collet Die and neck tension on the case neck. I collect the case neck, depending on if the drill blank is +, or -, I insert it into the case neck, and check how tight or loose it is in the neck by putting my thumb over the primer hole and checking the compression on the drill blank in the case neck. I also found out, that, if I collect first and then bump the shoulder back it greatly reduced case neck run out. I check all of my rifle cases on my Neco concentricity gauge for case neck run out, over all bullet run out and I index them by the Banana curve. I am very OCD. By indexing the Banana curve of the case, that insures that each bullet case Hight spot or low spot is sitting in the same position in the rifle chamber. "Yes I have been down a many rabbit hole." This gives me a, BUG EYED one whole at 100yds in my factory barrel rifles. I can't ask for more out of them, all I can do is, to try to do my part behind the rifle. I hope this helped in some way, but this is how I do it. I'm always looking for a better way, and one day we will fined that magic POST on here.:) [/QUOTE]
