Outers Foul Out II
I have been out shooting my 2 44 magnums. A 240 grain Meister .44 cal bullet with 10 gr. Unique and these foul up the barrell, badly, in my Ruger Super Blackhawk, that is magna ported (with a 6.5 inch barrel) and a Taurus Model 44 Stainless Steel, factory ported.
I tried cleaning it with chemicals: Shooter's choice, Butches Bore Shine, and good old Hoppe's no. 9. None of them worked!!!
Next, I tried Outers Foul Out 2 on the Ruger Super Blackhawk first. I cleaned the handgun in 1 hour. Then I tried it on the Taurus Model 44, it took 4 hours. In cleaning them them I had to tape the ported end of the barrells with electrical tape and then fill it with the Foul Out solution. I poured out the chemicals after 30 minutes and then cleaned out the black gunk with Shooter's Choice and a swab. The swab was so dirty and had to make approximately 5 passes to get a clean swab and then refill with solution and let the machine go to work again. This means I had to strip away layers of lead and then clean out the fouling with it. By the time I was done, I could have strip out enough for a half of a bullet out of the Ruger and a whole bullet out of the Taurus. The integral compensator sure does collect a lot of lead.
Also, for your information: The handguns weigh the same and I was a little hasty about magna-porting it but I had it done anyways. When I compared it against the Taurus integral porting the Ruger's magna-port kicks less and less muzzle flip. They both work though. Just clean it every time you shoot lead bullets through it, as all the fouling underneath the layers of layer will eat pitholes in your gun. As it has happened to one of my inlaws.
