cast plinker load change to magnum primers?

Primers are pretty scarce these days, and if that's what you can find, just drop back a bit.

last year, I unearthed a thousand Remington 9 1/2M's that were buried in a ammo can of unused powders. Not really buried, just out of sight from a move in 1994. Found two lbs of unopened RL-12 I couldn't find though.

I used most of them to light up Trail Boss loads in my .243/7/08/.280/.30-30/.35 Rem./.35 Whelen. I couldn't see any difference.

I wouldn't swap them out on a max load of 4895 under a heavy bullet, or a hot varmint load on a hot day for that matter. For practice loads at the low end of the charge range, you should be fine.
