Hello friends,
I cast for my three 30 cal rifles. My favorite mold so far is my Lee C309-150F. It has done very well for me at lower velocities. It drops at .301 at the nose and .311 on the bands.
I now want to step it up to about 1800 fps for my lever action for an upcoming hunt. I bought some Gator gas checks. The won't "snap" on the base of the boolit and fall of, even after going through the sizer. Has anyone seen this before? Do I need Hornady's?
I have had good luck with Gators on my 7mm and my .357 boolits. In fact that is all I use on those.
I have beagled the mold to enlarge the base and this makes the checks stay on. They then crimp tightly after passing through a .311 Lee sizer. The problem is that beagling makes the nose too fat and it engraves the rifling on the boolit. That isn't necessarily bad unless I want to clear a live round. Yesterday I had a boolit stick and it dumped powder everywhere.
Thanks in advance for any help.
