I have always used 7 mm rem mag cases to make my 264 win mag cases .I also always used 308 and 243 to make my 260 rem cases both the 260 and 264 were not super easy to find .I want to anneal my cases for both of them .I guess 9 have to do it before I size them down to make it work right .My old cases I made never split but lately with once fired cases I fired I am getting split necks .I also finally found a bunch of once fired 264 win mag cases and I was told by a 264 shooter that you have to anneal them also because they also had split cases .I use to anneal mine with a candle and it worked good .I will probally use a propane burner this time .I hope these once fired 264 win mag cases work good they are Winchester from the factory cases .Its almost impossible to find brass for these two now so you gotta do what you gotta do !
