44Magnum and standard Large pistol primers

[epags]

FWIW: Winchester Large Pistol primers are the only brand that claims to work with regular and magnum. The others (to the best of my knowledge) make a separate primer for regular and magnum.

I use a lot of Blue Dot in the .44 and .41 with cast bullets. Can only get 2 to 3 inch groups at 200 meters with open sights. Have never used a mag primer with this powder.

Never used a std primer with 296, but only use 296 with jacketed bullets.

I've loaded a ton of 44 mags with various jacketed bullets and H110/W296. I never considered using anything but LP mag primers. Wasn't the 44mag their primary market??

Over the decades, I've loaded many, many thousands of varied magnum loads for handguns and carbines, and the vast majority of those loads, cast and jacket, were loaded using standard primers. If a mag primer gave better groups, then I would use it, or if I was hunting in very cold temps. Blue Dot, 2400, H110, 296, Lil'Gun and a few surplus powders have all been ignited by varied standard primers. I can't recall every having one that did not ignite. YMMV

I have always used magnum primers with W296
especially in the .357 Remington Magnum. Almost sure that when I started loading, back when Pluto was a pup, that the reloading manual suggested magnum primers.

go with the Winchester primers as suggested if you want a super accurate load that's fun to shoot it's a cowboy load put a 250 gr cast bullet over 6.0 gr of win 231 it's fun to shoot and u will be amazed at the accuracy.

H110, W296, AA Enforcer, 2400, Unique all fired with std primers,(CCI, Fed, Win) and have over 4k rounds thru my 41mag never have I had an issue at any temp. Only trouble I had was FTF with seller an bellot.

My 44 mag is used to my save my *** from ponderous beasts in all weather. Always used magnum primers for those loads and standard primers for plinkers.

None of the AA powders require a mag. primer, nor does 2400 or blue dot... I use a lot of Tightgroup and Herco for lead in the 44 and that is standard or win primers too. The slower ball type powder ought to get a mag. primer just to ensure great ignition, but other than that a standard primer will do fine.
