Probably try all of the above things soon enough.
I did get my guns hook of the shotgun type action welded up and I filed/refitted it.
No doubt that it was one of my main problems with getting things to shoot in it.
I have probably lost a couple of years work down the drain and most likley have re do alot of stuff again.
I know that if I size my cases and be just over groove diameter well seated with a hard wrap and a sealed paper and then an alox coat and then a coat of grahite or flour to stop the alox sticking in the case necks it does shoot.
But I'm more happy not having to size my cases at all and use a fuller filed chamber.
About the only thing I can say for sure is if I put a cardboard wad under the pp bullet then a small grease wad with the log powders then I have better results.
I believe that the gas flow from the bullet exiting the case neck is sealed off better filling the gap of the bullet chamber clearance and helps on the start of the bullet base getting a good start into the rifling.
Well just for a micro second anyway.
I have to work up the load as it does increase pressures or seems to change the harmonics in my rifle thou.
I have loads for 2206h and 2207 but 2206 which is in between them (no longer made) my rifle just hates for some reason.
Any way back to soggy patch fixes and all things pp.
I asked my brother about bees wax and he says that the hive glue that the bees use is just tree resin and wax.
And after you melt it and and get all the legs and capping muck out its pure.
Just wondering if that bee glue could be worth exploring ..not that I have a hive or such.
