A philanthropic member sent me a box of those Remington 260gr Accutips to experiment with and characterize. Having recorded all the dimensional characteristics, I will try to hit the range one afternoon this week before I pick Julie up at the park-n-ride. I will do at least one water shot at close range and if the accuracy yields tight groups, perhaps a water shot at 100 yards, besides bullseye accuracy testing over a chrony.
A couple of interesting initial observations. The cases are sized to yield a rather narrow case just above the web of .493 as opposed to the Hornady cases being right at, or close to .500. That's going to be a rather loose fit in the chamber. Also, the necks are taper crimped to .473-.474. A little smaller than we typically use. If their lawyers feel that is a safe diameter for the mouth, we all can taper crimp a little tighter than we have been doing. Could help with slower powders using lighter bullets. Food for thought.
Watch for a range report in the next few days, depending upon weather and how crowded the range is after work. The tear down and rebuild date is Aug 13th-22nd, so there will be a dead spot in my activity during that time frame. As the Rifle Range Coordinator, I have to be there with my hat and whistle

EDIT: I spoke too soon. They apparently don't use any crimp at the mouth. Mic'ing under the stereo microscope, the mouths are all over the place varying from .473-.480.
