This is why I asked the question, running low on Federal 210's. I did purchase 400 large rifle Bosnian primers from the nice gentleman who ownes Budget Shooters Supply. I could of purchased more however, I heard that it is hit and miss with these primers plus, they are more difficult to seat in the primer pocket.
My 240 Wby., 270 Win. and 30-06 are just at max load and hesitant of compromising the loads and rifles. The easy fix is to locate Fed. 210's however, they are rediculously overpriced from greedflation sellers.
Pmed you.
