Thank You all for the info. I've learned more on this sight than all the others I've posted on including Paper Patching ones.
I bought this 9.3x72 drilling as kind of a nostalgia thing, in the 1960's I hunted with one but it was before I got really interested in firearms. I was handed the rifle and ammo and went out and killed stuff with it. I have good memories of how those big bullets did the job and how sweet the drilling handled. I remember they had nothing but lead sticking out of the case, no copper jacket. I was hoping I could load soft lead paper jacketed bullets in this, but as I'm learning more about it, it is looking like it might be a dead end.
I'm going to order some S&B ammo to give jacketed bullets a try in it and then, if they work might just leave it at that, it won't be a high volume rig anyway as I have a few modern combos and drillings that I hunt with.
Thank you again for all the info.
This is one of my favorite sites as double guns and drilling are my favorites, old and new.
