300 Weatherby primers

[PRR1957]

I need to load some 300 Weatherby with N-160. I cannot find any LRM primers, but I have Federal 210M and CCI BR-2. Has anyone tried substituting these primers for magnum large rifle ?

Try it, but Cold weather will be the real test.

the 210M/s should work just fine.

I’ve read where the freebore in the weatherby could cause a dangerous secondary combustion if loaded light or trying to use a lighter primer.

You should'nt need magnum primers with N160. It's in between
Ramshot Hunter and H4831. BR2's also have a harder cup, so I
would start there.
