[QUOTE="magnum, post: 557513, member: 2432"] Thanks for the input and i appreciate the effort you've taken to contribute to this decision. But just a couple of comments on them: 1. As good as it is, I don't want another .308 Norman Mag. Cases are hard to find and are relatively expensive. Plus I don't want to get the cases mixed between the two rifles. 2. Although this is a long range rig I am considering, it is a "hunting" rifle and therefore needs to be capable of being carried into the hills/mountains as well as other gear day pack etc, and I'm on the wrong side of 50 to be seriously considering a 12 lb rifle for this. There was an interesting series of article in NZ Hunter last year on a long range hunting rifle build (eventually it ended up in 7MM RUM) and it weighed less than 8 lbs (after skeletonising) and was capable of taking game to beyond 700 yards, as I recall. 3. I mentioned I liked efficient cartridges. Although the 300RUM is a great cartridge and I've looked at it (on paper) a bit and can be loaded back to 300 WM ballistics it is less efficient than the 300 WM at this (i.e. takes more powder than the 300 WM to get 300 WM ballistics out of it, according to Chuck Hawkes, see [u][url=http://www.chuckhawks.com/300super_mags.htm].300 Super Mags.[/url][/u]). That's why I proposed the possibility of the 30-338 as it (like the .308 NM) can produce 300 WM ballistics with a few grains less powder than the 300 WM. 4. I am surprised no one mentioned anything about the 30-338, it seems to have a pretty dedicated following and was the record setter (in 1,000 yard target matches) some years ago 5. The other thing that interested me is the news of the XM2010 that is being adopted by the US army and its corresponding round, MK 248 MOD 0 and MOD 1 in .300 Win mag, giving a 220gr SMK a muzzle velocity of 2,850 fps out of a 24" barrel. That seemed to me to be pretty impressive ballistics and with my rifle/build with a 26" barrel I figured I could get around 2,950 fps out of a 208gr A-Max or the 210 gr VLD hunting bullets. Heavier than this, none of the major bullet makers seem to make anything in a hunting bullet. In any event with the game I am most likely to hunt here I figured the 178-180-190gr weight would be pretty capable out between 500 to 800 yards (my "target" distances). As I said, great input and keep it coming. Cheers, Magnum [/QUOTE]
