I dumped a 43 grain load into the first shell and didn' t seat the bullet, didn' t like the looks. And the Speer 13 book does list it as a load for the .270 up to 150gr. I' m using a 130gr Speer Grand slam bullet. I like the H4831 and have used this in my 338.

So here is my delema. I primed about 40 rounds with magnum primers for the H380, which it called for. Can I safely deprime them and save the components? I really don' t care about the primers, but would like to use the brass. Can I use the mag primers if I use the 4831?

Thanks.
