How's the state of the barrel effect that?

Beerhog the 303 Epps and the wildcats versions are bloody good cartridges.

Probably a scary number.

Possibly get the smith to modify a 30-30win FL die the same time as the barrel chamber gets done . Opinions anyone?

Would a 30-30 be an option? Just thinking reamers and dies and cases - and you could run any .308” spitzer…

There are other rarer rimmed cartridges from Europe, 9.3 x60-something. Having said that,35-303 would be interesting. Dunno how it would go feeding though. Martini actions big and small favour bottle shaped cartridge for feeding in the chamber. I’m open to ideas on another cartridge

7x57R maybe? Virtually identical to .303 but with the advantages of 7mm long-range aerodynamics and excellent bullet choice from 78gn to 215gn.
But really I would just use .303 and buy your bullets now instead of waiting until you need some, availability becomes irrelevant when they're sitting on your shelf.
