58 g vmax loaded?s

[zr600]

Ok I shot some loads today all were 31.5 8208 cci 450 seating depths of 2.250 didn't get velocity on this one. 2.255 velocity was 3471, 3498, 3501, 3426, 3494. Then 2.260 velocity was 3437, 3435, 3450, 3431. Then 2.265 velocity 3474, 3532, 3471, 3466, 3473. Then 2.270 velocity 3440, 3433, 3412, 3426, 3386. Target pictures are left to right shortest to longest.

Ok hear are the pictures these were sat 100 yards. Would Greg and Ritch try and do anything different with these loads or try and up the powder charge .2 to see what happens? I was kind of wondering if the velocity varies were they much or if it's ok? Give me some ideas these are all 5 shot groups.

I would start at 31.0 and go up in 0.3 increments to 31.9. I would shoot two groups at each level. I would get on the lands if I could or as clisr ss posdibke. Then next trip 0.005 more.

I rarely shoot only one group on these little guys. I am using a pedestal rest and rear bag.

I don't think you can reach the lands with a 58g vmax can you?

Check your rifle. By now you should have all the tools. Reloading measures shouldn't be based on some one else's gun. Reamers change and shooting a great deal moves the throat. I shoot a great deal.

NEVER shoot a chamber on a non-SAMMI cartridge unless you check the distance to lands...period.

NO not and have enough bullet for the case to hold on to.
