231 has been one of the fastest powders made. Hard to believe someone would print loading data recommending a mag primer.
In my limited experience, I have loaded tons of 41 Mag with 20 grains of H110 and standard primers with absolutely no ill effects and any velocity difference was not noticeable. In theory you may have some unburnt powder but I haven't personally experienced that with H110. Of course other's experiences will vary but for sure, you won't be doing something unsafe.

Just to further the discussion, I shot a bunch o non-canister equivalent to Accurate #9 in a wildcat based on the 357 Mag case tapered to .319. It used lead bullets fired just subsonic from a custom single shot bench gun. My primers of preference were Federal SR Match. This combination shot cleanly and accurately in my rifle, but this discussion got me wondering about the relative strength of these primers vs the others under discussion.

There is a lot of information out there regarding the use of small rifle primers in place of small pistol magnums. For CCI at least, the two appear to be the same product in a different package.I have a new can of Winchester 231.I would like to us it for 357.mag. some of the loads call for magnum small pistol primers. I don't have any mag primers .is there a danger in using standard primers.
Absolutely, and to further put a point on it, CCI has a BYOP (bring your own primers) program where you supply the primers and they make factory reloads for you. They will load your ammo with SPP, SMP, or SRP primers for you - whatever you have to give them.This video is well worth watching if considering interchanging primers when reloading. Facts over opinion is the only way to go.
