[QUOTE="AZShooter, post: 1242133, member: 5219"] I know I was not representing a 7 rem mag in the proper light with my friend's load. I was just making a comparison. Mudrunner, The 7 rem mag with 168 velocity you got is more like it! The 308 win looses under those conditions. BC sure makes a difference even at mundane velocities. My favorite high BC low velocity rifle is my long throated 338 RCM shooting the 300 gr bergers at a sluggish 2525 fps. That package weighs 14 lbs with a #7 profile, 1 in 9 twist, 30" barrel in a Joel Russo stock. Its downrange performance is amazing. AND I can shoot 5 rounds in a row with the barrel only getting warm. At 4000 ft where we hunt our coues wt here is its performance: numbers are wind drift in a 5 mph crosswind and energy respectively 100 .15 3987 200 .65 3740 300 1.6 3506 400 2.8 3283 500 4.4 3072 600 6.3 2872 700 8.9 2682 800 11.9 2502 900 15.3 2331 1000 19.2 2169 While I like super fast cartridges like the 6mm-284 and the 257 Weatherby, these high BC sluggish chamberings are lots of fun too.
