Fitted a 358 barrel from a 35 Sambar, cut the chamber off and reamed to 6.5x54 MS with a 35 cal pilot then 35 neck and shoulder reamer.
What I call " 35 Carcano ", a bit more than a 35 Remington and a bit less than 358 Win.
I'm about to start developing a load for it using 180gr hard cast powdercoated projectiles, most likely 356 Win load data or 358 Win start loads.

L-R 35 Rem, 35 Carcano, 30-30 Win
