Dave, H110 in the 44 or the 41 pretty much require a mag primer in my experience. A standard primer will make them all go bang, but some will bang better than others. I substituted standard for mag primers some time back and before I got to try them, my son stopped by and borrowed a piece and some ammo, without asking. Turns out this was the ammo he picked up since I wasn't here at the time. Came back that evening with the piece and all but 6 rounds of the ammo claiming the ammo was [fouled] up, and I should know better than to load such crap!
We know the mags work, so I'd stick with them unless you just want to experiment for yourself.
