[QUOTE="del2les, post: 1235241, member: 9299"] My 300 RUM in a Rem 700 action, 26" SS .650 muzzle with 2 inch 3 cavity, side ported brake, in a Laminated stock loaded with a Nosler 180 AB on top of 100gr Retumbo @ 3,425fps shoots 3.4" @ 600 yards, but the other Rem 700 action in 300 RUM wears a 26" fluted SS with .850" muzzle with spiral Magna Brake inside a McMillian stock shoots 210 Berger VLD hunting in the low 2"s @ 600yds. That load clocks an avg. 3,049 fps over 90.0 gr of Retumbo with a GM215 Match primer. The deer to varmint varmint calibers, 25 thru 22, can shoot low 2" to 1.5" groups. The 25-06 with an 85gr Nosler BT on top of 60 gr MRP shoots .3 moa @ 600yd. The 22-250 AI's will shoot 75 gr Amaxes into 1.5", and sometimes less, 600 yard groups, and they routinely shoot low 0.2" at 100yds. If there is no wind which is almost never in this area, I have an old "Red" built BR rifle in 222Rem that shoots low 0.1's @ 100 and will hold similar @ 600. But ANY wind and the light 50gr match bullets just love to drift over two inches at 600. Strangely, my 6mm's aren't shooting under 2.5 to 3 inches at 600, and that may be due to the 1/9 twist I'm shooting the 105's in. Once those barrels are toast, I'll change to 1/8 twists. [/QUOTE]
