Dirty bore shooting

[Kurt]

Eric Shooting dirty is a combination choosing the right bullet and a good lube. The lube I use is very soft about the consistency of real butter that has been out of the fridge about 15 minutes or just a little stiffer then shortening that is still cool and when you squeeze it with the thumb and finger it squishes very easy. I use a OJ carton wad or freezer paper between the lube wad and powder and a very stiff wad under the bullet that will scrape the bore. The thing with just the freezer paper over the powder is to leave a lot of lube behind from the heat of the burn. I have pulled bullets that been loaded and I found no signs of the oil separating into the powder. But maybe it's the Vaseline in my mix that holds back the migration. My lube does not have oil in it.
The bullets I use for the PP is a tapered bullet from Tom Ballard and I use the tapered Gibbs from KAL as well as a undersized bullet but I like the tapered bullets better so I can use a little harder alloy to hold the setback of the ogive to keep the lead off the bore.
For the GG, It's very hard to beat the 121 PH or similar that has a ogive that is tapered right to the front driving band. It will feed no matter how bad the throat is fouled. I just shot two magazine tubes full of .45-70 rounds out of my Marlin CB lever rifle it holds 9 rounds and I shot them with 2F OE as fast as I could lever that rifle.
Don't count the flat nosed bullets short, they will reach out just fine and hit the iron hard.
