Done some shooting this morning... awful!
The least worst was done with slightly thick paper, however I followed exactly what Matthews said in in his book "The paper jacket'.
My bore mesures .3035 from land to land, bullet is sized 304", and I tried two papers .0015" and .0025".
Bullets patched mesures .311" and .315", and they don't work at all.
I will have my sizer enlarged to 305" and we'll see.
For the moment I'll follow your advice, I'll bought Remington core-lokt. I'll never be ready before the ending of the hunting season with my paper patched bullets!
