Thanks guys...just what I was trying to get across to a fellow the other day...a 160gr (.270/7mm) are so close in diameter that they are the same, in the field for sure. Yeah the 270/160 isn't as BC as some 160/7mm, but close enough that under 400yds it doesn't matter. And for a "point and shoot" guy it sure doesn't matter, ha. I guess I'm excited that this is the "very first" 270 I've had (this is #6) that shot the 150/160s well! They all shot well ( well, one Mod 700 MR was a shotgun) with 130-140s. A few shot the 110 OK, but not tight enough for prairie dogs & such. And I just can't get over how fast this rifle shoots those heavies! I "cut my teeth" in bolt guns/reloading with a .280 then on up through the AI to magnums and I learned how to trust a 7mm bullet on game. Anything comparable gives me a warm fuzzy.
Jim, I don't know how they're calculating that BC but I always wonder about such calculations. If you compare the same brand and style bullet, one in .277 and one in 7mm, I would think the .277 bullet would have a slightly higher BC, all else being equal due to its slightly smaller diameter.. Now if you're comparing something made by Berger with different profile to a SGK or Nosler Partition, yeah maybe, but Berger makes VLD bullets in .277 as well.
