Re: accuracy in load developement
My verticle is about 4.5-5" at 725 yards, and the horizontal about 3". It could be my shooting technic on handling recoil, or something in my reloading. Brass is annealed after every firing, full length resized, trimmed, uniform pockets, deburr flashholes, necks turned only to clean up thickness. I use a RCBS Chargemaster 1500 and double checked charge weight on a balance beam . Last night conditions were good for shooting, with know mirage, and a 2 mph wind. I did notice a slight difference in neck tension on a couple of rounds when seating the bullets, even with the necks turned to 0.0145 thickness. I was surprised by this, as I would have thought with the necks all the same thickness the seating of the bullet pressure would be the same.
