Barrel erosion? :?
Not sure what you mean by that.
Before I picked up reloading . I shot up few umc value packs the crimp is not very smooth and some have had feeding issues but both my Xd's gobbled them up.Not very clean would blacken the end of my silver armory coat in a couple rounds but all functioned and grouped well
I've never had a problem with UMC in 9mm. I've shot a lot of it. I like reloading the UMC (R-P) cases. They seem to have good brass thickness and neck tension. Maybe a little dirtier than others but not excessively so.
Like the others, I have no idea what is meant by barrel erosion.
But, yes I've used that ammo quite a bit in my XDSC (9mm). It always went back and I had FTE issues. I've fired with some being a little hotter than others. But it's been a good inexpensive plinking ammo for me.
basically eating up my feed ramp and the beginning of my barrel because of bad powder or whatever. i dont know if it happens with pistols, but ive changed a couple of m16 barrels because of that
your not going to see any barrel throat erosion unless you start pushing them babies to 3000 fps and fire 30-40 thousand of them...lol. As a matter of fact, you wont even need to replace a pistol barrel until you have well over 100,000 rounds through it.
You want to see barrel erosion, try a 55gr bullet at 4200fps, then you'll see barrel erosion :shock: . I think it was called a 22 Cheeta or somthing like that, and the barrels lasted about 1000 rounds.
Of the about 3000 rounds of UMC I've put through my XD40, I haven't had a single problem with it. One of my shooting buddies and I went through case in one day each, and neither one of us had a single problem. I would reccomend it for anyone looking for cheap ammo, but I don't shy away from the Winchester White Box at my local Wal-Mart either.
A early high velocity varmint round the .220 Swift was notorious for barrel erosion. For service issue pistol ammo like 9mm, .40 S&W, .45 ACP and many many more, barrel erosion is non existant. Our handgun barrels will likely serve many generations to come.
