Sorry if these questions have been asked several times before but I am new to reloading and a bit baffled.
I would like to load some lighter loads of lead for my 10 bore (inland Scotland) than the factory loads of 63g. I have a simple original Lee loader and a RTO tool.
Is it dangerous/wrong to use the RTO closure in place of a star crimp on (say) standard Alliant recipes, I believe? that roll crimping reduces pressure slightly.
Also if a recipe for a 3.1/2 inch load asks for 1/2inch of packing inside the wad can I reduce the cartridge length to 3inch and dispense with the packing then close with the RTO?
Thanks for any answers
