[QUOTE="winmag, post: 398436, member: 22166"] Winchester Mag primers are as light as Id go on that big of a cartrige. I only use Federal 215 Mag primers (cause theyre as hot as I can find) on my 300wby, and yours has a bit more case capacity if Im not mistaken. There can be a BIG difference in the way the powder burns (or doesnt). Primers are definately not just primers. There are some cartriges that can cross over between the lg, and the lg mag such as the wsm family etc, but yours aint one of em. Youve got a big column of powder to set off with an insufficient primer. You may want to back off your load just a tic and swich to the proper primers, and work back up. There may be a bit of a pressure issue if your loaded heavy on the powder and trying to light it off with a large rifle primer( designed for 308,30-06,270 etc) vs the Mag primers(designed for large case capacity 300wby, 300rum, 338 win etc). Be carefull, but Im guessing youll like the results alot more with the right primer. [/QUOTE]
