CCI No. 300 Large Pistol Primers

[Hi-Standard]

Just bought my first brick of CCI pistol primers(have always used Winchester). Now the Winchester large pistol are good for standard and magnum loads, anybody use the CCI 300's in say 44 magnum?

No responses?

It'll depend on powder, some loads require magnum primers while others don't.
I also read people tried using both magnum and regular primers with loads requiring magnum and saw no difference.

I don't think you'll have any issues with any .44 RM load. Load your ammo and enjoy.

I guess you were short of responses because this question, or variant, has been answered soooooo many times on the threads.
Short answer. Use standard pistol primer in any pistol calibre, including all the magnum calibres.
With any powder suitable for pistols, including the magnums, and yes, even if you use H110, or W296.
If someone is telling you to use magnum primers with certain revolver calibres and/or with certain powders, it is something they have read in a book, or been told, but all the experienced reloaders I know, use standard primers.

Yep. For both light target loads and full power magnum loads up to 24.5gr of H110. They worked fine, no issues at all.

H4831 was the one who told me to not bother with magnum primers and he should know with the amount of .44 Mag he has shot.

Yeah, use them. If you experience inconsistent ignition or erratic velocities (large deviations) you probably need to go with the Winchester Primers, or a magnum type of primer.

Thanks Mark. I always think back to what did people do before magnum primers, of any sort, rifle or pistol came along.
Maybe you remember a while back I delved into when magnum primers first came out. Briefly, 1961, Jack O'Connor article listing primers available. No magnums.
1962-63, Ellwood Epps catalogue, no magnum primers.
1964-65, Ellwood Epps catlaogue, magnum primers available.
Those powders, and calibres, some claim magnum primers are needed for, were in popular use long before the above dates.
