Doesn't sound ignorant. My advice, for what it is worth, use the primer stated in the load instructions. If that primer is unavailable, use the beginning load with the primer you have and work up.I may sound ignorant but I would like to know: The manuals I have call for large pistol primers for 44 magnum. Yet I read here and elsewhere that some shooters used magnum primers instead. What are the applications for this?
Thanks, ngashooter. This has been very helpful. I have been reading my Speer manual lately and will read the section on 44 magnum loads again.Large Pistol Primers describes the size of the primer. They come in Large and Small sizes just like rifle primers. Each size is available in Standard, Magnum, and Match. The difference between standard and magnum is the intensity of the flame produced. When you load big .44 magnum cases with full loads of ball type powders the extra heat of magnum primers provides a more consistent ignition. Flake type powders light off easier and often standard primers work fine with them.
And This One Two ..... I like Winchester WLP ...I believe Winchester large pistol say for standard or magnum loads (to lazy to go downstairs and look) they are my preference. I do load some 44 mag and heavy 45 colt loads with cci magnum primers only for very cold conditions. When it's under 20 degrees H110 likes a little more fire to get going
Great reply. Thanks.Lots of good answers here. There are always lots of variables when working up loads for each gun. Are you loading for range/target shooting or more of hunting/self-defense levels? Short barrel or long barrel?
Example ... I do a lot of loads for .38/.357 ... when loading for my 3" Model-13 I use smaller loads of faster powder with standard primers. When loading for my 8" 586 I'll use slower burning powder with magnum primers. The magnum primers make sure the larger / slower powder charge gets fully ignited. The goal being efficient loads that burn all the powder in the barrel to create the results you want.
If I shoot slower burn rate powder in my short barrel gun, I get a big muzzle flash of fire out the muzzle. That is not efficient and just burning powder out in the air. Most all manuals will have powder burn rate charts that will help you get the idea. Always start low and work your way up.
The powder dictates when to use a magnum primer .
Some slow burning and ball type powders need the extra oomph from a magnum primer .
In the 44 magnum there are only two or three powders that need it but most powders can get by just fine with regular primers .
Follow the directions in the loading manual . You will soon recognize which powders do better with magnum primers .
The old standby 2400 can go both ways ... I have seen loads used with magnum and loads with standard primers with 2400 .
H110 usually needs a magnum primer for best performance .
Just go by the book ... Speer Manual is a good one !
