You need to slug your bore as there are many different configurations to the rifling in the 9.3x72. Some will run as small as .358 and work well with bullets for the 35 Rem. The rifling in mine has narrow but tall rifling having a .344 bore and a .360 groove diameter. I'll be trying some 348 Win. bullets patched to .364 and some .358 cast bullets with a 36 cal. greased wad under it.

After the first shot the rest are just noise.
