I see on the H&R/NEF site that .357 and .44 mag rifles can't have other rifle barrels fitted to frames, but can have shotgun and muzzle loader barrels fitted. Is that because the .357 and .44 mags are on SB1 frames? If not, is there some other reason?
Also, are the H&R sportsters on SB1 frames? I've heard that the sportsters have offset barrels to all rimfire firing. Is that true?
Thanks,
