[QUOTE="rpierce, post: 1738604, member: 20643"] So I got some Warner dies in for my 300 norma magnum improved. Ive never seen brass sized that consistently before. Runout on sized brass is under a half thou. Very preliminary testing showed a wide and accurate node at a mild 3145 fps with a 215 berger and 92 gr of n570. I loaded up 91.4-92.6 gr in .2 grain increments. For the ladder test I set the target at 1000 yards and hooked up my Target Vision camera. I started at the higher charge and worked my way down. I didn't let the barrel cool long enough for the 92.2 gr shot. After that I let the Riflekuhl stay in the chamber for 2 minutes between shots. Minus the flier at 92.2 gr there was 3.712" vertical for 6 shots at 1000 yards. 5 out of 7 shots in this ladder test had .877" vertical/ .083 moa. They landed in that tight of a spread with a 20 fps Extreme Spread for a 1.2 gr window of powder. 91.4 and 91.6 gr were .456" apart. Ill be testing 91.5 as soon as we get another cool and calm day. I used my lightweight 300 norma improved that's under 8lbs without optics. Kelbly action, manners EH1 stock, proof carbon sendero barrel, self timing 5 port, Hawkins bottom metal, Triggertech diamond trigger, Kahles K525i, Modular Evolution bipod w spikes. I had no problem watching the vapor trail as the reticle barely left the 1000 yd target during recoil and always went right back onto the target. I was back in the bulleseye by the time the bullet was halfway to the target. Rifles are instock and ready to ship.
