Ditto 303 Sav from 30-40 Krag.
Aside from a lot of work, shooting one in a 30-40 Could be interesting since the headstamp is wrong and world is filled with dummies.

I've been a reloader for over 50 years and I've reformed so many cartridges from other parent cartridges over the years , I've never had an issue
its not for everyone .. but he can make 303 sav out of 30-40 ..it should be turned on a lathe .. A couple of decades ago 303 sav brass was crazy expensive and very hard to find.. I've made and formed brass for the 303 lots of time from 220swift, 307 win 30-40krag 303 brit .. maybe another one or two I've forgotten about .. now brass can be found and its reasonable really no need to reform brass for it at this time .. but you do what you gotta do when you want to shoot your rifle . its a good skill to learn ..
by the way Graf's and son has some in stock
