Mine is a ULA, not a NULA, model 24, got it in 1997, .270 WCF asked for a 26" barrel 1.5 lbs heavier than standard, rifle weighs 6 7/8 lbs. with Leupold VariX III 2.5-8 in Weaver QD mounts which I preferred to Melvin's. It is a superlative rifle and you cannot go wrong with a 7'08 although arguably - and this is what Melvin told me years ago - the best power to weight ratio in the model 20 comes with a .284WCF !!
