If'n ya get it you will be hooked, and if you decide to start doing reload, i have some very sweet loads that I wouldn't be afraid to use on Moose.....Seriously. The Barnes TSX for the 30-30 is an out standing bullet, and with the right powder it will do it's job if you do yours. Get it, you won't regret it. Joe is right, it was about 1908/1910 when they went to the .311, and I have seen some early, 1903 and 1905 that slugged out at .308, the bullet loaded into the early rounds was usually a .311 bullet, hence why a lot of the old ones show a .311 bore. UMC and Western went to the .308 bullet in about 1912, at least that is what I get from the bullets I have pulled from cartridges from that time period. The Winchester 303 Sav Case holds about .02 grains more of water than the Winchester 30-30 brass does. Still doesn't mean you can push it too hard, especially if it has a serial number under 95,000. Over that, if the rifle is in great shape, yeah you can push it a bit, but I don't. Les
