Leading issues with HBWC seated backwards

[TXBryan]

Very informative replies; thank you! Scarcely the first one to try this obviously. I appreciate all the benefit of the collective experience. I'm not really looking for some super fight-stopper load. More like experimentation to verify what I'd read realizing there are better choices available. Seems like this practice raises its head every so many years and gathers a little attention. Thanks for the knowledge! Bryan

I was able to reduce the leading in my M13, M15, and NMBH by seating a sized, inverted gas check behind the bullet. IMO, it acted like the W-W "Power Piston" wad in their shotshells, keeping the high-pressure gas behind the bullet, away from bullet-bore interface. I even found a few of the gas checks, blown flat with powder-side blackened, bore-edge rifled, and bullet-face clean. Same trick worked for .375/.38-55 WCF.
Kinda unscientific, I know, but it worked for me.

Sometimes the the "unscientific " way works just fine !
I don't know why I never thought of the gas check idea , I have several moulds that are cut for GC and use them regularly.
Learned something new today... Thanks Larry , good one !

I love experimentation and having the curious post thier results. FWIW I was OTJ about 20 years before anyone* was authorized to carry HP ammo. I have seen a lot of criminal perpetrators laid low by regular old standard pressure .38 Special Target LHBWCs (loaded as lHBwc). It is certainly more effective than 9mm FMJ.

*There were exceptions, but exceptions prove the rule.

One of the methods I have used to minimize leading issues has been to apply a light coating of pure white lithium grease (auto supply houses, about $4 per 8-oz. tube), wiped on with my fingers prior to loading and seating the bullets. This little bit of added lubrication performs well beyond any expectation! Lithium grease is a premium lubricant, not affected by the usual powder flame temperatures, and having a melting point well beyond anything seen in small arms ammunition. I can apply a thin film of lithium grease to bullets while watching the TV news, completing 500 or more within an hour.

mind a bit of leading with lead bullets, I just plan on dealing with it at the cleaning bench later on. Not the end of the world at all. Just a few more strokes with the proper tools to keep your pistol in prime condition.

Lithium grease is oil based. Since oil can seriously affect the powder burning I would guess this would be a bad practice.

I DO mind leading. ANY extra strokes are unwarranted in my mind.

With the proper lubrication, lead alloy, bullet diameter vs. the barrel, and bullet velocity there should be no leading.
