What do you look for when your looking for extreme spread. I ran some loads thru the crony today looking for a node. Not looking for group but looking for the smallest extreme spread. Its worse than looking for the right combo of load, bullet, Col.
of the # rounds I fired I got the following info.
The crony didn't record the actual #5 so I ended up with only 9 acutal recorded round.
68.36 Extreme spread
yesterday I shot 10 rounds thru the gun, A 700 Remington, blue printed, 26" Hart barrel .300 Ultra Mag with all the bells and whistles and I ended up with an 82.XX ES 93 grains of Retumbo, Nosler AB Federal 215M primer and Remington Case.
I'm using 93.3 grains of Retumbo, Federal 215M primer and a 200 Nosler AB. Maybe I'm looking for the holy grail but I'm trying to get my ES down to at least single digits. Am I dreaming. I'm getting a bit over 1/2" groups and am trying to get them down to 1/4" if possible but its going to take a single digit ES to do it. Is Retumbo the wrong powder to use or would differant primers do the trick. I sure would like to get this thing dialed in before the barrels gone. [img]/ubbthreads/images/graemlins/crazy.gif[/img]
