Norma loads their 6.5X52mm Carcano ammunition to produce 360 fps higher muzzle velocity than their 6.5X50mm Japanese Arisaka ammunition, with the same 156 grain Alaska bullet. Chuck Hawks noted this 6.5X52mm load runs about 100 fps behind the 6.5X54mm M-S. This helps explain (to me) how my 6.5X52mm Carcano carbine was effective for me as my first hunting rifle. Wikipedia lists 2170 fps with the 162 FMJ from a 445mm (17.5 inch) barrel. Plus I could shoot it over and over and never complain about recoil fatigue even at age 13.

Not all Carcano rifles and carbines were manufactured using gain twist rifling in their barrels. IIRC mine had a 1940 year of manufacture stamped. It had no bayonet but a lug was on the barrel. I understand these take a .268 bullet instead of. 264 which makes using non-milsurp ammo a bit of a dice roll. I only found milsurp ammo to use in mine at the time I had it.
Hornady some .267 160 grain SPRN 6.5mm bullets.

Prvi Partizan offers some .268 123 grain RNSP 6.5mm bullets.

And some .268 139 grain FMJBT bullets.

Norma interestingly enough only offers (and I suppose uses) .264 6.5mm Alaska bullets.
