I have a few hundred rounds of each the calibers I shoot, but six of my pistols use 9x19, and since three of those are titanium cylindered airweight 637-2 J-frames, I use 147gr in all six to protect the titanium cylinders in the Smiths. I'd like to stock up on two or three thousand rounds of that. I ordered a thousand once fired cases yesterday and found 250 147gr jhp jacketed bullets, but so far, no primers or powder.
Should I also look for sr, sr Mag, and sp Mag primers & grab whatever is available? I'm assuming they all would work in a pinch, as long as I don't load to max.
