[QUOTE="Blitzfike, post: 1723442, member: 807"] I've been forming brass for wildcat and obsolete calibers for almost 40 years. In most cases, I don't use anything special. On some conversions, I may have to use multiple dies and steps to get it done. Most of what I form now is 30 and 357 herrett from 30-30, 375 winchester from 30-30, 7.65 argentine Mauser from 30-06, 8mm mauser from 30-06 and 7.62X25 from either 38 special or 223. I also form 7.7 Jap from 30-06 and have formed 243 and 7mm-08 from 308 brass. On some I have to turn the neck due to thickness after forming, on others, I have to use an undersize expander because the necks are thinner. When I uses military brass for something like 243 win, I have to reduce the load because of reduced case capacity. I machined all my expander plugs and tempered and polished them for my specific needs. I normally use full length sizing dies for the forming operation and have never broken or worn out one in all the years I've been doing it. I own and use two different Dillon RL-550B presses and I would never think about doing case forming on them. I use either a RCBS Rock Chucker or a Lee 50BMG press for the forming operations. I personally think it would put way too much stress on the toolhead of the Dillons doing forming on them. I have the Dillon Rapid Trim as well as the RCBS powered trimmer and they make lots of difference in the trim part of the operation. I used a Lyman and a Forster manual trimmer as well as hardened trim dies before I got the powered stuff. I tried annealing before forming and that led to a much higher rate of failure in the forming operation. I now anneal after I have done the major forming operations. The use of a really good lube is an absolute requirement in these operations. I have used everything from home made concoctions to all the standard brand case lubes and find that Imperial Sizing Die Wax works best for me in all applications. Don't be afraid to try your hand at forming brass from other calibers. Good luck Blitzfike [/QUOTE]
