Use of Large Rifle Primers in Magnum Rounds

Hi,
I have a heap of LR primers and intend running in and zeroing the new 7mm Rem M. Can I get away with using LR primes as long as the case capacity is at or over 85%?

Thanks

Hi Ian, LR primers will be fine. I usually use the Federal 210 in the 7mm RM anyway. It helps keep the burn rate slow. I really only use magnum primers in ultra mag capacity cases or with spherical powders.
