So as far as the casting and loading goes. Guess we will more then likely be doing it for 9mm now, unless I come up with a good 23 upper at a price I can not refuse.
I already have 9mm dies, and a trimmer, just have to dig them out. Plus I load for .380, already.
I have a Lee 358-150-1R. It casts at a narrow .358 so it has been sitting on the bench so to speak.
So a .356 or 7 sizer and I should be good to go.
I have loaded these bullets, at .358. Powder coated. For the worn out Maverick 9mm (Pre-High Point) and they do well.
Should be an easy transition for me.
The Gun smith says I should go with a land and groove barrel for lead.
He said Polygonal, it is not as big a deal as most people make out. If you watch pressures. Especially in 9mm, as long as they keep their barrel clean. Develop and stick with a proper load, That does not lead in the first place. Most problems come from production lead bullets. Being the wrong size or too hard. (sound familiar?)
Sizing and keeping things at proper pressures matters, period. Especially with Polygonal.
But.... with land and groove, less variables. I will be working with a riffling type, I am already familiar with, and is more forgiving. Especially, If I want to start using the same load for 2 or more guns.
I could probably just re size the Bullets for my High Point load to .357 and use that load for both guns.
Well, we will see I am getting ahead of myself again.
