I recently purchased a Smith and Wesson 9mm Model 659. Does it matter if I use brass or steel case ammo? Will one make the barrel or other parts wear faster?
I agree with Jonesy! These days it is getting to where you use what you can find and get, but brass is the way to go.If it is all you can get, a little steel probably won't hurt anything, but it would be a last resort. Aluminum is a little better than steel but brass is best
