	I've never done any case forming. This is new to me. First can you form 25-20 wcf from 32 20? How difficult is it and where can you get forming dies? I see on Midwayusa that 25-20 wcf has gone from seasonal to discontinued. Some help is needed.

	Forming dies? Normally, that's just using the 25-20 sizer and it should work well if appropriately lubricated (not too little, not too much). If too much resistance or wrinkles, annealing might be required (unless you - but nothing special to form 25-20 from 32-20

If too much resistance or wrinkles, annealing might be required (unless you're using too much use, that will also cause wrinkles) - but nothing special to form 25-20 from 32-20. After all, they're pretty close. Try forming 577-450 from 24-gauge brass, now that is quite a bit harder...

	I resized about 90 32-20 into 25-20 WCF using a sizing die and case lube. I lost a few at first due to operator error and hard brass. I annealed them and it worked much better. Dave

	Get your self a trim die and use it for your first pass. then use the 25-20 WCF die set. You won't loose and and won't have to over anneal your brass. 40 Rod
