[QUOTE="MagnumManiac, post: 1120791, member: 10755"] This is totally up to you, but I do not fire form any of my improved cases with bullets. I just don't see the point of hunting with a round that is 100fps or more SLOWER than the parent case, and wastes barrel life. I fireform with a fast pistol/shotgun powder, Clays is great, it has a high load density for weight, start with 1/3 of case volume/maximum charge with 100% load density, and increase in .5gr increments until a case comes out fully formed. I use a twist of toilet tissue, 1/4 sheet for 22-250 size, 1/2 sheet for '06 size case and full sheet for all magnums, twist it in and poke until it 'squeaks' a bit and is tight, but not too tight, fire, and done. Have also plugged the case with bees wax, candle wax, potato and pumpkin, all work to form brass. I have also used non calibre ammo bought from the LGS cheap to just fire and form brass, it's amazing how good the brass comes out even with the bullets rattling down the barrel. Have used 300 H+H in 300 Weatherby, 340 Weatherby and 375 Weatherby to form brass. Also used 375 H+H in 375 Weatherby. If I get factory ammo really cheap, my 22-250AI and my 257AI will get that ammo used in them to fireform, but this is not regularly how I do it. Cheers. gun) [/QUOTE]
