That's a gorgeous design, and nice execution in the machining.... Only thing is, I had nothing to do with the .308/.300 20" twist bullet barrel, only the .300/.294 26" twist pellet barrel.... I have designed BBTs in .308 in three weights, however, 79 gr., 95 gr. and 111 gr.... but the heaviest of those may not work in the 20" twist.... Molds are available from Accurate....Bob
Thanks for the gauge link, I see the gauges I need. (5k 210*sweep 1.1 inch) That is a sweet design, and a really nice gauge protector. Your split receiver is giving me ideas you enabler.
I noticed that most of those gauges are O-ring sealed, I have no problem making a seating surface.
