Hi Jim Tom
I would play with charge weights a little. I noticed when I was load testing I went down a whole grain and the group tightened up quit a bit. I was chasing a fast load and when I dropped the powder weight it all came together. I then played with the seating depth and that gave me the grouping I wanted.
To clarify a little, I had a load I worked up, worked well. Then I tried a different projectile, with that same charge weight, that was my problem. I tried to save a bit of time, but it caused me problems.
With the new projectile, I should have started my ladder testing from the beginning.
As the barrel in my rifle was a thin fluted one, I only shot 3 round groups. And had to wait for the barrel to cool. The way I see it, it’s a hunting rifle not a target rifle, so in the field I will not be shooting more than two in a row too, quickly.
Ladder testing is fun. Good luck
