Not sure if you guys saw it, but Craig Boddington (think he made General) was getting some pretty stellar velocities with the 26 Nosler in Guns & Ammo. He clocked a 140 AB at 3,425 FPS out of a Nosler M48 with a 26" pipe. That means that 3,500 should be a snap with that 129 ABLR pill. Not too shabby. Relative to SD, not sure if you can get to 3,400 with a 7 Ultra and a 160 grainer and I don't think you can pull off 3,400 with a 190 in 300 Ultra. Nope, that's 30-378 Bee country and means you're burning 122 grains/shot with a just a smidge more recoil. You gotta love it when a company underrates its products or is conservative in its reporting. Kinda reminds me of the muscle car era when the big three were reporting that their 426, 427, and 428 big blocks had about, ohhh, 300ish horsepower to get around insurance companies. Kuddos to Nosler.
