[QUOTE="Trnelson, post: 1285775, member: 42308"] It depends. If I am forming from 270 brass I just use a cheap 120g bullet. After reaming out the neck to work with my chamber a trip through the sizing die and a trim to 2.487" I load 50.0g H4831sc and fire it. The fired case ends up 2.484" and perfectly formed. I anneal after fire-forming and neck size from there on. Most of the time I anneal after the third firing and pitch them after the fifth firing. Recently I have had reliable success using Prvi Partisan 120g bullets. My rifle doesn't shoot fire-forming loads well enough to justify sticking a premium bullet in the case, so I do not waste them on that. With bullets less than 100g I have had ok results with a few not fully forming on the first go around. If I am starting from a batch of .25/06 I have done it both ways but have had the best success usually using the COW method to get to 90%+ fire-formed then the cheap prvi 120 to finish forming the survivors seated out to touch the lands. Normally, I figure to lose about 10 out of a batch of 100 due to necks splitting or a case head thinning too much to be safe or even rupturing during COW fire forming using 25/06 brass. Then a good annealing before loading my rifles preferred load. I try NOT to use 25/06 brass as it starts out too short and has to flow quite a bit to fill and form to the chamber. That usually leads to case heads getting too thin or even failing within three 'full' loadings. That's a lot of work to do for just a few firings, especially when 270 brass is plentiful. [/QUOTE]
