“F.Guffey,
When I started reading your post I thought for a minute you had wrote your first legible post that wasn't going to go into forming first then firing??.....
I believe there are a few members on this forum that are dumb enough to believe that, I do not believe you can be fair and or objective, since Ed kicked you in all 6 knees you have taken on the nature of an Alabama Leg Dog, or maybe that is the reason he kicked you in all 6 knees.
This is a bench rest forum, again, I am not a bench rest shooter, I do not have problems with do-nuts, nobody on this forum knows what causes them, then there is the “widely indignant about everything element’ that will not allow the topic to be discussed.
Again, I have formed 22/6MM Ackley cases using 25/06 cases, the smith building the rifles had 55%+ case head separation/failures, he was very proud of the 45% that did not fail, like you he did not understand the methods and or techniques, he was/is a fire former, chamber a round, pull the trigger and eject a case that is fire formed, he cut the chambers???? When I cut a chamber I know the length of the chamber, I know how far I have to go to finish the chamber, I know the length of the chamber from the face of the bolt to the shoulder/datum. It is possible you are not capable of keeping up, not a problem, I cut the chamber, I form cases to fit, when I fire a case in a chamber I cut there is .000 head space, there is no excuse for someone calling themselves a bench ‘rester’ not to know how to operate a press with dies and shell holder.
I accept your thinking, you can not correlate the sizing process and it’s effect sizing has on the chamber when it comes to offsetting head space, I choose to eliminate the effect the chamber has on the case when fired by forming first. and I am the fan of time is a factor, we can not get into that, seems anything new and or things you do not understand ‘locks you up’ and causes you to display a behavior that leads me to believe you are socially dysfunctional.
“It seems 257 Roberts brass is hard to come buy and 7x57 brass is also hard to come buy..
does anyone know what case i can make 257 Roberts brass from..I think i can just neck up 6mm Remington cases and fire form them. I can buy factory ammo and shoot it up for the cases. that seems to be a good way to get the brass i want..
Bozo699 Wayne, the question is about 7mm57 and 257 Roberts, 257 Roberts cases cost me .08 cents each plus my time and investment, I would like to see you make a contribution, the OP ask a question, can you help him? Is this about you? Is this forum about helping?
If I had one forming die die it would be a 308 Winchester, if I had only 2 the other one would be a 243 Winchester, this is THE bench rest forum? I do not wakeup every morning and start over, methods and techniques are accumulative.
And, again, I make annealing equipment, I do not sell annealing equipment, but there is risk in discussing something new and or something Bozo699 does not understand, I run the risk of locking him up again, my opinion, he has a strange way of demanding attention.
