Carcano .300

Post by TWNuss »

Hello! I'm new to the forum and live in Longview, WA. I have a beautiful Carcano rifle with fully functioning folding bayonet. On the side of the base of the barrel, ".300" is stamped into it. 7.35 ammo seems to fit it perfectly. I've seen 6.5 Carcanos and 7.35 Carcanos but never a .300. Can anyone help? Thanks! :D

Greetings from Vancouver WA not BC. I'm not a Carcano expert, but you should have a 7.35, looking at the Hornady dies page, listing "7.35 Carcano (.300)".

I have a 7.5 Swiss which is a 308/7.62 bullet, and the Russian 7.62 bullets tend to be about 0.311 to 0.312 diameter. Then, the 8mm Mausers aren't 8mm and the 8mm Steyr Mannlicher is even larger in diameter yada yada yada. ...so it is no surprise to me that the markings are confusing.

Welcome to the forum :clap:

I would use some caution. I do not own 7.35 Carcanos so I am sort of way beyond any expertise. But because 7.35 is hard to buy, some of those were converted to odd calibers to shoot. I have seen a 7.35 that was marked .300 SAV on the top where the 7.35 mark is, and had a large letter S on the bolt handle. That was a chopped sporter back in the day. An S marked bolt indicated a German 8x57 bolt. Germany converted some Carcanos to 8mm, some have an S on them. You need to do some research or take it to a gunsmith or better yet ... post the rifle in the Carcano section. Ren Hoek and Airforce1 are both big time experts and should be able to tell you about the rifle. But, post pictures. I know just enough to say it's odd and use caution. Sorry I cannot help. I do not remember seeing .300 stamped on the side of the metal on any 7.35 Calvary carbine, but I avoid that caliber so I can not remember. I have never seen the bottom markings on a 7.35 barrel. The stock should have 7.35 marked onto it and also the top of the barrel. PLEASE post photos of the markings and receiver in the Carcano section. I would be interested in seeing the results or PM, Ren Hoek. But a picture is what we need. Is the .300 mark visible on the rifle or hid on the bottom of the barrel under the wood? It sound like it's stamped on the outside of the action and visible while the action is in the wood? Something a gunsmith might do on a conversion. Here is how to post a photo: viewtopic.php?f=79&t=2203

Here is some further documentation: https://www.calguns.net/calgunforum/sho ... p?t=205093


Steinel makes factory ammo if it is 7.35. I have always avoided this caliber in Carcano due to ammo. I only have 6.5 Cavalry carbines.

It can’t be a caliber designation or measurement put there by the Italians...it isn’t metric!

Maybe a gunsmith slugged it and the owner wanted the diameter stamped.
