Hi Tom,
we had in Austria at that time 3 different types of 9,3x72R
loads.
1.) BP loads with lead bullets
2.) Nitroloads with flat bullets (soft point) with reduced
quantity of powder.
3.) Nitroloads from Sellier&Bellot and DWM with 193 grain
spitzer and flat softpoint bullets.

I use an old o/u sidelock DR custom made in Vienna in the above mentioned caliber with extrem good hunting results for deer and also for short distances of boars during chase hunting.
