For single shot folks, make north fork bullets softer so that they can expand more, and offer Trophy Bonded Bear Claws in a wider range of bullet weights...the only knock on a frames, and this is only when pushed hard, is sometimes you'll get a double mushroom..one in front of and one behind the partition..I'm a big fan of Woodleigh Weldcore and Norma Oryx bullets, but they're not perfect either
