I always get a kick out of the blow up tests. Interesting, in the abstract, but essentially meaningless to ordinary shooters and collectors. Unless, of course, you want a collection of blown up rifles....
Also interesting how many people found fault with the clip system, but only a couple compared its drawbacks to the M1 Garand (which has, essentially the same drawbacks, except for clip availability in the US)
My personal opinion on the Carcano is that I don't much like them. Nor do I much like the Moisin Nagant. Personally, I think they are both miserable bolt action rifle designs. Not that they aren't well made (the good ones, anyway), rugged, or accurate, I just don't care for their designs. They are plenty good enough for what they were made for, though.
One of the reasons (not already mentioned) Carcanos got a bad rep is that there is essentially, nothing else you can do with them.
In the decades after WWII, when milsurp bolt guns were both plentiful and dirt cheap, the Carcano was at the bottom of the list of desirablilty, if you wanted a nice rifle. Mausers, Springfields, & Arisakas were versatile, you could easily make them into
nice sporters, and with a bit more work, into
fine sporters.
The SMLE was near the bottom of the list, but above the Carcano, mostly because ammo was more common, and you didn't need special clips. Plus the SMLE was "on our side"....
Moisins weren't even ON the list. Not because they were so bad (they aren't, quality wise) but simply because there were none available, essentially. Moisins are the hot ticket now (although they are drying up), for budget & beginning shooters/collectors only because, being communist arms, they never got to the US market until well after all the (best) of their contemporaries had been bought up by us.
If you are looking at them as historical items (milsurp collection), the Carcano is a good rifle to have to fill out a collection. If you are looking for something that is easy to feed, look elsewhere.
