303 British Neck Sizing die - Use for 7.62 x 54R?

[dmftoy1]

This is probably a stupid question . . .but would it be possible to use a .303 Neck Sizing die to neck size 7.62 x 54R? I'm guessing since the .303 is longer that the answer is no . . . . .but the cheap bastard in me has to ask.

I'd advise against using a 54R neck sizer for 54R. I've found full length resizing a MUST if more than one rifle is being used. There's considerable variation between chamber dimensions.

how about if you only have 1?

(isn't that a general rule for neck sizing anyway?)

Even then the 54R seems to work best if it's fully resized. The only exception would be with pre-war Finns or match rifles. Lee has die kits for like $20 so it's not a huge outlay. I can't see how .303 neck dies would work given the length difference, but you could try it.

I emailed Lee regarding an out of spec die I had and also inquired about a collet die for the 54R, which they don't make. They stated they could probably piece one together from other dies for the price of a standard collet die, but it wouldn't be stamped as a 54R. You might email them and ask.
