[QUOTE="J E Custom, post: 1983850, member: 2736"] When I shot the Corbon 395's I had the same problem and ended up with a face full of debris so maybe that was what they used with the hard cast loads. I found that Lil'Gun got the best velocity and burned clean so that is what I use. The problem I had was the lead fouling the barrels of both the pistol and the rifle at these velocities and pressures. Lead is hard to see without a bore scope, (With a bore light the bore/lead looks very shiny and clean, But a good bore scope tells a different story) I have cleaned many pistols that were leaded and shot terrible with jacketed bullets because of the pressure and the amount of lead fouling from using Cast bullets. Gas checks were used to prevent cast bullets from melting under the existing pressure and heat of high pressure loadings. it appears that normal cast lead bullets are good to about 800 ft/sec. most Hard cast are rated good to 1400 ft/sec. and 22,000 Psi (28,000 CUP's) this will normally cover most hard cast bullets, beyond that You should use gas checks. But the pressure of the 454 and 460 S&W reach pressures of well over that and (53,000 to 57,000 PSI for the 460) and so the pressure and velocity is well beyond the hard cast bullet's ability in my opinion unless you load down. I hear what the guys are saying about the hard cast bullets being a hammer for bear hunting, and as long they are aware of the barrel leading they can take steps to keep their pistols clean. The only thing I can see is that their are other bullets that have more energy and don't lead foul barrels that will perform the same on big bears or other dangerous game. The 454's and 460's are high performance pistols and the rules are/may be different for them or any other pistols that are high pressure and high velocity. Just a caution J E CUSTOM [/QUOTE]
