Shooting the Carcano is either for the very rich or for the handloader.
Prvi Partizan manufactures Carcano ammunition at this time, as does Norma. The Norma is quite terrifyingly expensive, the Partzan unavailable in Canada, although you can get it from Graf's in the Excited States and through Hornady. This is the same ammunition as marketed as "Highland" in Oz, Kiwiland and Sath Efrica.
Fortunately for us, everybody and his dog makes the dies these days. RCBS are very nice (I have had a set for 30 years now) and Lee Precision makes serviceable dies for about half the RCBS price. Partizan brass is available from Trade-Ex (link at the top of this page) @ $35 a bag of 50..... and it is Boxer-primed.... and they also have the special Hornady bullet in bulk packs, at $39 for 100. This is a correct-diameter 160-grain bullet which can be used to duplicate the military loadings.
SOME rifles will accept and do very well with regular .264" slugs, but most seem to need a larger diameter. If you are unsure, try them all, but do be aware that boat-tails just do not obturate very well (if at all), so, likely, you are better off to stay with a flat-base bullet. A good point is that the very wide lands in a Carcano barrel seem to last half of forever.
As to powders, stay with the quicker types. I am getting good results with powders in the 3031 - 4985 - 4064 range....... but I load for the Carbines with 4198 because I just cannot handle the fireballs and ear-splitting reports which, thankfully, are nonexistant with the Model 41.
IMHO, the Model 41 is the best of the whole Carcano series. As well, there really were not a whole lot of them made: Walter in "Rifles of the World - 1st Edition" estimates "perhaps 1,000" built at Turin, of which an incompehensible number seem to have appeared in Canada in just the last few years.
I'm just happy that I got mine.
Loading data is in most of the loading manuals, but generally seems to be developed with the 21-inch tube on the Special Forces rifles. The '41 has a 27-inch tube and should develop significantly higher velocities with any given load. TEXT BOOK OF SMALL ARMS - 1909 gives 2395 ft/sec with a .266", 163-grain bullet at a mere 38,304 psi out of the 30.75-inch barrel of the original Model '91. The low pressures combined with the relatively small diameter of the casing mean you will be getting a whole bunch of loads out of a pound of powder; factory rounds used only 30.2 grains of powder, so you should get over 225 rounds out of a tin of the stuff. This compares rather favourably with the .50BMG API at 27 shots to the tin of powder: yet another "plus" point for the Carcano.
Have fun! That's what it's all about!
Hope this helps.
