I gotta say that this last batch of Winchester 230 grain .45 ACP ball ammo seems to be way dirtier than the last PMC rounds we bought. After today’s session at the range I took this before and after cleaning photo of the muzzle of my Warthog. The Glock 30 was also very dirty.
We’re also having some problems with Winchester both 12 and 20 gauge shotgun shells in our Remington 870s. We bought the shells in July and thought that our shotguns were due some maintenance because of the sudden tendency for shells jamming on the ejection cycle. When we switched to either Remington or Estate shells we had no problems.
Winchester .45s and shotgun shells are off our list for target shooting. In fairness to Winchester we have never had problems with their 9mm Luger ammo.
I am not sure if this is ammo related. The Warthog has a relatively short barrrel; thus you may have powder that is still burning as the projectile exits the barrel. There very well may be a significant amount of burning powder exiting the barrel and depositing residue as it leaves. With a longer barrel you may have less of this occurring. Did other brands of ammo produce less fouling?
This ammo also fouled my Glock 30 more than usual. I can’t recall having that much with the last PMC ammo we used. We shot some Wolf (the Russian brand) a while back and it was also quite dirty.
To solve the problem, Be a true shooter not a weekend warrior and reload your own. Then you have no one to blame but yourself. You custom taylor to barrel length, application(Self Def., Target, Hunting, ect.)
