This is going to cause some blowback. If you are loading .38 spl or +P or .357 to be used in a .357 revolvers, Small Rifle Primers work just fine. Load a few up just check to see if your hammer has enough power to strike the primer and set it off. Brisance of a SRP is about the same as a Magnum SPP, and they are exactly the same size.
Down to 2000 SPP to be used in other cartridges and had an excess of SRP and used them in the revolvers. Very slight increase in fps. which I assume corresponds to slightly higher pressure, and the harder cup proved no problem with the .357s.
Trying 9mm bullets in .38 loads, be interesting to see if there is a loss of accuracy. Trying to use everything in my inventory to prevent spending outrageous money in todays market.
