Ive never been one to reload until recently when i traded a custom rifle for a semi custom rifle and reloading equipment. The rifle i traded for is in 7 rem mag but the one i have questions about is an old FN mauser deluxe i picked up that has been rechambered from 30-06 to 30 B. Newton. All i can find is that 30 B Newton is 30 Belted Newton or 30-338. Im finding places that make brass or even loads but is quite expensive. Im questioning selling as i dont have much interest to rebarrel and ruin that beautiful rifle by putting a modern barrel on it. What would i be looking at for reloading cost wise? Any help at all would be greatly appreciated, i would also like to ask if the two rounds really are the same or are there differences. I read the creator of the 30 Belted renamed it to the 30-338 because he simply necked down 338 win mag to a 30 caliber so he could hold more powder. Is this true?
