I have been running the 270 bulldozer out of my .338 Norma mag this season. As far as data, I personally know a fellow long range shooter using Badlands 265 grain solid elr bullet, and has used a .475 G7 to make impacts out to over 3000 yards. He has an 8 twist in his .338 Tejas I believe. I personally am using a .407 G7 with the 270's. I was sceptical of the advertised bc as well, but decided to try them. I can't afford doplar, or Bryan Litz (no disrespect to either), but I have verified drops out to 1153 yards so far. Got my velocity from a magnetospeed, zeroed at 100, converted the advertised .803 G1 bc to .407 G7, then shot out to range using my .338 Norma mag topped with a March 2.5-25 optic. 3 shot groups at 700 and change (pictured below) and 1153 were under half MOA, and perfect elevation. Shot several more times ranging from 500 to 800, and drops were all spot on. Confirmed on a pronghorn at 661 a couple days ago too, so I feel the bc's are pretty close. You may have to adjust slightly, I have had to do it with Berger bullets too, but they are gonna be pretty close. I haven't shot farther than that, as this is mainly a hunting rig, but I will eventually stretch it out further. Thats why we field test, as you stated.

For more information you can check out this thread too -
There seems to have been rising interest in these bullets, but information is spread out and somewhat limited, so hopefully this thread will help consolidate information. I would like to keep this thread somewhat organized, accurate, and to the point. If you have first hand experience please...
