i might suggest that you contact mark chanlyn in colorodo mark only makes stainless barrels and i will tell you this some may be making as good a barrels as hin but none are better but he only runs barrel at certian time for calibers so he might be on 22 caliber and could be month before he will run that caliber but you might try dave gentrys son as he stocks a good many of markks barrel and iam not sure he even make a 0,3 barrel i wil tell you this i own two 9,3 original husvarna rifles on 98 actions and amercian flat missed the boat on this caliber its as good as it get for medium size game from my exprience i woild never give up my 375 but i would never give up my 9.3 either reciol is milder and it kills out of reason gor what it is oh grafs it the best place to get brass has been my exprience also
