Can only speak to the one ball powder am using alot, 748. Never had any hang fires/etc, but noticed a distinct improvement in accuracy when using Rem 7 1/2 in 223 and Fed 215/CCI 34 in 308. The improvement was over standard Fed primers, and haven't done any comprehensive testing of multiple primers.

Also shoot in colder temps, and accepted the writings about use of magnum primers with ball powder in colder temps. Frankly have never done or read about a comparison in below zero temps.

Am thinking that maybe the phrase "harder to ignite" could also be synonymous with "providing consistent ignition" or something similar.

Am betting there is several on this forum who may know about actual detailed testing, perhaps by the military.
