8 Gauge Bore Leading

[Ed Blake]

Cleaning the WH Monk after the Southern I noticed significant lead in the bores from the forcing cones to the muzzles. A Chore Boy copper scrubber on a bore brush and Kroil got most of it out. But how to avoid this? It was recommended to me to use a plastic wrap in the shot cup so I ordered a big bag from our friend in Alberta. What is the experience of 8 bore shooters using this wrap? Is it an effective means of preventing lead in the bores?

I had a significant leading issue when I went from the SP-8 Remington wad to the 8ga Hi-Capacity wad. The shot cup in the Hi-Capacity wad is much shorter. If u fill the short cup with filler wads it leaves most of the lead unprotected. I solved the problem with my reverse stack load. Most of the shot is in the shot cup since the filler wads are under the plastic wad. For me it has completely eliminated the leading problem. Powder followed by a .070 8ga card wad, then the 1/2" filler, then the 8gs Hi-Capacity. I had the load test by Tom Armbrust.

Thanks Craig. What an interesting concept. Is there much pressure difference between the reverse stack and the conventional stack loads?

Bit of adjustment .

Thanks Craig. I’m not sure why my phone does that.

The stacked load was 1163fps, 7066psi, the traditional load was 1183fps, 6833psi. Basically the same.
