I’d be looking at stability programs before I’d try, even before I’d buy a box of bullets. There’s several programs on the internet.

Elevation and temperature, humidity are some variables that could effect stability. Just because one guy says it works well for him doesn’t mean it would for everyone in different environments.

I’ve been shooting 35 caliber bullets since the 60’s but have not shot anything over 250 grain - maybe 275 grain once, but I do not recall accuracy and had no chronograph then.

My biggest 35’s are a Whelen and a couple 350 RM’s. A 358 Norma likely would push a bullet faster.

I prefer classic.
