Ladder tests ???

Don’t get to distracted by your last results. Ladders shot with only one shot per powder charge can be confusing since other factors can and will influence impact. 3-5 shot groups in a ladder will allow you to rule out any odd fliers. When shooting only one shot you can’t rule out poor bench manners, condition changes, muzzle blast from a bench next to you, etc

Run your test again with 3 shots per powder charge and report back.

I'd appreciate some feedback on my ladder test. I thought I had a real winner yesterday. See photo.
6.5 Creedmore in a Bergera with a deep throat, and a Vortex Razor, using bench and sandbags. Shooting Hornady 147 ELD and H4350 powder. Loaded each round up .3 gns. Shot at 300 yards

So to day we took out 3 rounds at each of these powder charges. I'm not impressed. Maybe 2 groups in under 1 MOA.

Got me confused and disappointed.

Looks like 40.6 to 41.1 is where I would concentrate.

Thanks guys. 40.3 to 40.6 gave us sub moa.

Start with a luke warm charge, run a seating depth test, then follow Erik Cortina’s method for finding a node....

What's Erik's method.
