[QUOTE="Pdvdh, post: 349360, member: 4191"] Hey, I'll be looking for a response now too. I didn't know there was much difference in barrel life between the button and cut rifled methods. I think Fiftydriver is now starting to use some cut-rifled barrels in addition to Lilja barrels. I suspect any differences in barrel life are suttle such as to be hard to definitively determine. It would show up in the barrel burner cartridges quickest. So the benchrest type calibers may not show the difference as quick as the LRH crowd touting the relatively overbored barrel burning cartridges. I know Michael had a terrible time with a 300 RUM in a cut-rifled barrel. He no more than got a sweet load developed and then the pressures increased due to increased bore wear/bullet friction and he'd have to re-tune his powder charge. Turned into a process resembling a dog chasing its tail. I've got a 25 RUM and it's the only barrel I'm likely to toast - not because I'll shoot it so much - simply because it's a mega-overbore cartridge. It's got a 30" Hart barrel. I have hardly shot it to date, but I expect the same problems Michael experienced with his 300 RUM. At least I know what to expect. [/QUOTE]
