Per 9.3x72r, I had the same dilemma regarding an older hammer drilling I have chambered in this caliber. I met a few of the folks from the German gun collectors at the vintagera event a few years back and was told that S&B loads this caliber down suspecting that people will be firing them in older guns. I have fired in mine with great success. I am not suggesting you do so only that it has worked fine for me. It's a great cartridge...

Hey Dave ,Nice Gun ! You need to get her out shooting ,I really get a kick out of mine ,too bad we don't have over lapping Grouse and Deer here in Pa. ,I figure I could use mine in Bear season and also do a little Grouse hunting at the same time ! That is when I see most of the Grouse I find any way ! Russ

I'm not even sure what a 32-20 looks like. What would it compare to in modern ammo ??

32-20 is .32WCF, still loaded and not remotely considered obsolete.
I'm down to one drilling and it's going to Baltimore this weekend. It's perhaps one of the finest of more than 3 dozen I've had.
two I sort of miss were Krieghoffs. One was a boxlock 20x20x.22 Hornet, and the other was a tiny hammer 28x28x 25-35 Winchester.

I have been really busy lately but have finally had time to get the Drilling Cased up just the way I want it :),thought you Drilling Guys may like to get a look ! I purchased a Three Barrel Canvas and Leather Case from Jeffs outfitters and fit the Gun itself ,Barrels ,Full length Briley 410 Tubes , Zeiss Diatal Scope Ammo etc ! All I am missing is a nice Glass Oil Bottle and 24 Ga. Snap Caps but eventually will add these to the cased Drilling when I locate them ! Russ

Wow! That looks great! Nice job. I think I may try to do the same.

Thank You ,I think the case was around $269.00 Or so and I have been laying Oak Hardwood Flooring so I trimmed up some scrap pieces to 1/4 " made a couple partitions and used the extra felt that came with the case to cover it ,I like things neat so I enjoy these little projects ,keeps me involved in my gun hobby without a lot of expense and makes them look special !
