My findings with the paper patched bullet

[Don McDowell]

I am fast becoming a bigger fan of the dual diameter bullets everytime I take them out for some shooting.
First off you can go with a larger diameter base than you would with a straight sided or tapered bullet. The smaller nose helps with being able to chamber "dirty". I've also found that patching about half way up that nose is plenty sufficient as the bullet seldom expands past the paper, especially when using 20-1 and harder alloy.
Those things are a pain in the butt to wrap.
I do think folks with the saami spec chambers may find those bullets to cure a lot of ills and shoot quite well.
Wiping routine with target loads can screw up a good load, if not done properly, and that includes leaving a trace of "lube" in the bore, and that's where I've found the water soluble oil and water mix to come in so handy.
I just shot two days with the dual diameter bullet, around 50 rounds per day. When I cleaned up Monday after we got home it took 3 patches. I blow tube that between shots, and wipe the bore between relays.
