Picked up a new Uberti 1894 earlier this year. This rifles bore has one those large bores diameters we hear about occasionally. Myself and my gunsmith both slugged the bore at .382" on 3 different occasions. Taylor Arms, the importer, told me it was .377". Talked with Bruce at Montana Bullet works. The largest he can size is .381". For both his 265 gr and 278 gr LBT Flat Nose GC, he agreed to air cool them (website says water cooled) so maybe the bullets would bump up .001" when shot. So far, I'm please with the 278 gr, giving me groups as small as 1.5" @ 50 yds for 5 shots using H4895 in Starline cases. Sights are the Skinner 94-AE version. Andy Larsson, Skinner Sights owner, took very good care of me. I've yet to try the 265 gr. Now that my hunting season just ended i'll have time to get back to testing.
