I seem to have struck it lucky with on of my first loads using paper patches.
Load is 35g ADI 2206 behind a wool wad x 430g hollow base PP bullet.
The mould is an RCBS .40-400 PP nose pour.
I wrapped the bullets with lined note paper .003" thick applied wet and later lubed with Lee sizing lube.
from left 435g .40-400 upright and lying down, 405g .40-400 flat base home made mould, RCBS .40-300 CSA.

Loaded round with paper patch.

I was really pleased to see this through the spotting scope.

The odd high one was one that I forgot to place a wool wad in and it went click/bang.
Point of aim is at 6 o'clock of the black.

The plain base bullet didn't do any where so good, about 2"
Here are a couple of pieces of the patch material.

The paper wasn't cut to ribbons at all.
