[QUOTE="Wile E Coyote, post: 675283, member: 28381"] Only have a moment here to reply to comments thus far... in no particular order. Thanks for the input all Regarding bushing selection: when I mention .308" or .307" bushing, those are the two I seem to use most often. I'm not set on any particular one and I could have worded that a little better. my fault. One thing I do differently and failed to mention is AFTER neck sizing. I measure the ID of the finished neck with a shopmade plug. After struggling to accurately measure the ID of the cases, a machinest friend made up a set of 'plugs' turned to .0005" increments. She made 6 for me for the .284 including .2835, .283, .2825, .282, and .2815. Fitting the tightest one without forcing is how I determine a .002" or a .0015" neck tension. Don't know if this is correct but this is how I do it. Regarding H1000: It may be on the horizon but I have 5 or 6 pounds of Retumbo yet to burn up. As for annealing: It's on the radar but resource$ are not there at the moment. and lastly, the muzzle blast affecting the chrono result: I made a plywood blast shield that is placed between the gun and the chrono. I set the chrono at the max distance the cables will allow and set the blast shield about mid way. the plywood is 30" wide by 40" tall (I had the piece cut to that dimension already) with a 3" wide x 8" tall hold cut in the center. The panel is canted away from the gun at about a 45 deg. angle with 2x3 legs to support it. I learned this trick with my old Shooting chrony Beta Master chrony. That unit was actually accurate BUT very succeptable to outside influences. Again, thanks [/QUOTE]
