I have a 625-10 that I shoot 230 gr. The kick is pretty hard but was wondering if larger gr bullets are more stressful on your guns or are lighter grains harder on them. I have seen these ka-boom stories and want to avoid that. I only use factory loads. Thanks

First, let me address terminology. A grain is a unit of weight, 7000 grains to one pound. You wouldn't ask, "What grain bullet is this?", any more than you would "What ounce steak is this?" Your question should be, "Is any weight bullet safer than another weight in my revolver?"

And the answer would be "no". The main factor is the pressure generated by a particular load, not the weight of its bullet. Many if not most manuals and manufacturers list loads with bullets heavier (and lighter) than 230 gr. that fall within maximum pressure limitations for the .45 ACP. Any of these will be safe in your revolver.

Thanks, thatmakes sense. I am stocked up on standard 230 gr Winchester and wanted to be sure that these were safe. Thanks again

You can also figure out the Power Factor of a load to get an idea of the recoil that it will have.

Take the bullet weight and multiply it with the velocity and the first three numbers will be the PF.

185gr x 900fps : 166500 or a 166 PF.
230gr x 909 fps: 209070 or a 209 PF.
185 lead 750fps : 138750 or 138 FP (target load)

All factory ammo should be safe in a modern gun, just a matter of what you end up liking.

Your 625 should safely fire any factory 45 acp or 45 autorim cartridge made.

230 grain ball loads are the standard 45 load.

I shoot 230 grain loads in my 1917, both factory and handloads without issue. Your gun should be stronger than mine.
