Don’t let your guns look like this
JR at A Keyboard and a .45 has posted photos showing a .50 BMG rifle that was not cleaned after shooting corrosive ammo. Makes me want to cry to see something that like so abused!

I’ve seen worst. Barrel is gone tho. It needs a replacement if you want to shoot it accurately. Just make sure the headspace is correct.
Thanks for the link Steve. It just breaks my heart to see any tool abused like this, especially one that I most likely will never be able to afford.
JR, My sentiments exactly!
