Hey all,

I have doing OCW's for my 30-06. So far I have completed the initial tests for 150, 165 and 180 SGK SPBT using RE15, RE19, RE22 and Varget. I have used On Target to plot my groups and I am trying to interprete the data. This is where I think I am lacking. According to what I have read on Dan Newberry's site, I am to look for a 3 groups that have the same approximate group center and the OCW should be the one in the middle and that would be the load to further develope.

:confused: My questions are as follows.:confused:

- I have several tests that have more than 3 groups with close approximate centers. In that case what would be the OCW?

- What is an acceptable approximation when comparing centers? 1/8" 1/4" 1/2"?

- I have read from quite a few sources that 3 shots are not statisically enough to determine a good grouping, 5-7 have been recommended. How many shots do you use?

- My goal is to work up a accurate and repeatable hunting load. So am I wasting time, money and materials making multiple loads on the light end as instructed? Or should I only load the light end in singles to check for adverse pressure and use the loads that have the desired velocity and KE for the OCW?

- Do you even use the OCW or ladder method, or do you pick a load soley on velocity and KE and go from there?

Any help would be greatly appreciated.

Thanks in advance!:D
