Fireforming Load Data with assorted bullets

[cbratcliffe]

I just bought some partial boxes of 6mm/.243 bullets to use for fire forming 6mm PPC brass at a gun show. At home I have 6 different partial pounds of powder that I would like to match up to these bullets to do the fire forming. The gun chamber is a 262 tight neck chamber and 14 twist barrel. What I need is load data for these combinations for just the purpose of fireforming some new .008 turned Lapua 220 Russian.

.243 Bullets:
Sierra 80g SBT #1515
Sierra 85g Spitzers #1520
Hornady 87g HPBT #2442
Speer 90g FMJ #1315

Powders:
Hodgdon 415, 450, 322 & Varget
Herc Red Dot
Alliant Reloader 19

I have a keg of VV N133 but don't want to use it for fire forming. I would also like to exhaust all the other partial pounds of powder before using that partial pound of Varget.

I plan on seating all the bullets to be touching the lands if not pushed in a few thou.

BTW, I have fireformed before using Red Dot and COW but have never been satisfied with the results so am going back to fireforming with a loaded round.

Anyway if anyone can give suggestions on loads for the above bullet/powder combinations I would appreciate it. Please keep in mind that I do not have enough bullets of any one type or enough powder of any one type to fireform all of this brass so will need multiple combination suggestions.

Thanks in Advance,
Charles

I didn't like the results I was getting from fire forming with COW either. I was using a suggested load of 8 grains of red dot and then COW up to the bottom of the shoulder then plug the case with toilet paper or wax or soap. It blew the cases out sorta but the shoulders were real rounded and some of the cases still had COW in the cases. I was about to do what you are thinking of doing and fire forming with a bullet which wasn't all that appealing to me because of running rounds down the barrel. Then another suggestion was offered and told me to fill my case up to the bottom of the neck with red dot and plug it with a cleaning patch rammed in real tight. That sounded like a lot of red dot but I gave it a try and it fire formed the brass really nicely or better than the 8g plus COW method. The shoulders were not real crisp sharp but a lot sharper than with the 8g COW method. And I didn't have to search my cases for leftover COW.

I use N133 of different leftover Lots mixed together for fire forming and use my 8lb jugs [of the same lot number] for practice and competition using the same full load [example 29.1 grains] for all three: fire forming, practice, and competition.
