zoner - send a frame in and get it fitted for a 30-30. It sounds like they got the bugs worked out at Remington. Just call ahead to make sure they have them in stock. I have 6 factory fitted barrels on 2 frames and they all lock up nice and tight. It is about time I get another frame - gun. I am thinking 30-06 or 308. Maybe a 25-06 or 280 and maybe a 35 Remington, sure would like to have a 358, or a 35 Whelen. The 357 max has got me hooked on 35 cal. All my barrels with the exception of a 223 have rimmed cases, but I am running out of options with those - unless I ream new chambers. It gets tough to decide.
