[QUOTE="J E Custom, post: 208126, member: 2736"] Roy is right about annealing the brass first but dont go past the finished length of the sholder (This will help support the sizing process) The reason it's collapsing the sholder is that it sounds like the die is also sizing the neck at the same time,this normally wont work. Two ways that might work, Find some 270 WSM brass and try them(Same size body as the 300 WSM but a much smaller neck. The other is to shorten a 300 WSM die by the same amount as the sholder reduction in length so your only moving the sholder then use you wildcat dies to finish the necks "NOTE" you may have to trim the necks some before the final sizing step. Ether way it will take two sizing steps to get you there ( Size the body and then size the the necks and then trim to length.(3 Steps) Some wildcats require 4 sizing steps. And use lots of sizing lube but take the expander ball assembly out so it want trap the lube and cause dimpling ,plus you will want to clean the dies when you are through with each step. After I posted I saw that you needed help with the annealing. It's easy hears how I do it. 1=Talk your wife or girlfrend out of a cake pan about 2'' deep. 2=Fill with water up to the level you want the annealing to stop. 3=Place 10 or 12 pieces of brass in the water standing with the necks up. 4=Take a propane torch and heat each case neck until it changes color(not red hot). 5=as soon as it changes color take a nail/stick and knock it over in the water. 6=Repeat untill done. I hope this will help J E CUSTOM [/QUOTE]
