Interesting! I hadn't seen this thread before. How does it compare to the 30-28N you had?I have my second 300 Wheeler barrel currently being broken in. This time I went with Mod400 steel. Should be a good test. So far so good. I will be posting results on Long Range Only.
Any further updates on this cartridge? I recently found this thread after looking high and low for any information on a 30-338 Rum. Surprisingly my search didn't produce much. I've been thinking for quite sometime it would be the ideal big 30 caliber magnum. I currently have a 338 Rum and use Redding 338 Rum type s comp dies. Necking down to .30 would be easy.Oh man. Weight. Probably 8 pounds. It's a 26" Bartlein 3B. Recoil isn't bad with a good brake. Same as a 30 Nosler. 300 Norma. Etc.
I did circle back to my N570 and 230 load at 3040. Same load as last barrel. Shot a 1.89" 3 shot group at 600 last week. She is off getting Cerekote now at Snake River.
