OCW vs Ladder vs Chronograph

[Adam in WI]

I'm trying to squeeze as much into my 1 hour outings as possible. Not ideal, but working with what my schedule allows. Actually, it's for this reason I was hoping the chronograph method was going to have a stronger showing. It's easiest strap on the magneto and record a dozen shots into the snow bank than to try and keep a barrel cool over 15 shots on an hour and a half at most lunch break.

My gut tells me that if I'm going to move to finer increments, I should perhaps use 2 shots per charge to mitigate the effect of barrel heat. This is a fairly thin tube. Thoughts?

You can do anything you want. It would be better to have more time and be able to be patience. For instance analyze your previous test and remove one bullet from each group and ask what would the test tell me? If you removed the "flyer" from 77.0, 78.4 and 79.1 it would have told a different story...

Another suggestion on your actual target is to use a straight edge to draw a line across from side to side so you are staying on the same plane when placing bullseyes (no slight up or down...)

I guess it depends on how much confidence you have in those two shots. Hard to pick a flyer/outlier from a choice of two.

You can be creative shoot one shot test on Monday, again on Tuesday and again on Wednesday; understanding that conditions can change...

Also, think of testing as fun and learning the art/science of it. You are not just learning about your load, you're learning about testing. It's just more fun with a 6br than a 300 mag

I've no idea to be honest why I even bought a 300. I don't hunt anything bigger than deer, at anything farther than 400 yards. There's no practical reason for it. The only benefit I can think of is that it's forcing me to be a better "technical" shooter. Being sloppy behind the stock or doing something silly like using a cross armed hold while the fore end rests on a bag is going to make you pay for it. That's why the random group with 210 Bergers; I wanted to get a taste for what the Win Mag can dish out. Lying prone gave the full effect for sure. So far my groups with this rifle are not that far behind what my Featherweight 7mm-08 posted.

I guess I don’t understand the ladder test at 300 yards I was thinking about trying it with magneto speed and
