[QUOTE="trophyhunter170, post: 527535, member: 30392"] Autorotate, Thanks for you info, it should help me a lot. From what you are saying I could basically work up my loads while fire forming the cases at the same time. I was planning on fire forming cases and then just truing the necks up. According to my calculations there should be .002 to .003 left in the neck. Neil J made my dies also and he wanted me to try the TN approach. I have used this approach with 6PPC's and 22PPC's in the past. No problem if I do not like it I will turn necks and use the .334 NK bushing. I might also experiment with some trail boss or pistol powder in fire forming with no bullet and use the case shoulder to set the cartridge head space. I use to have a 284 Jamison which 404 Jeffrey cases. Biggest mistake I ever made in a cartridge. It was a beast in its time and was accurate. But making the cases was a nightmare. I really got a education on case preparation. Nothing but chamber pressure issues. The rifle has been rechambered to a 7 WSM and works flawlessly and just as accurate. I have a Stiller TAC 338 action for this build that uses the same mag box you have which is center feed. I have never had any problems with center feed boxes. I have them on all my rifles because they are the best in my opinion. I also use the Boretech (best) and use patches only. I never shoot over 4 or 5 shots without cleaning. The way I break my barrels in it usually takes 20-25 shots, cleaning after every shot. I agree barrel heat and cleaning is the key to the life of the barrel. The load you mentioned, 103 G of Retumbo, is that your best load and what you are using now? You also mentioned some hotter loads which I would not start out with, but how was the accuracy for the higher velocity rounds. I will probably start around 100 G and work up. gun) [/QUOTE]
