Target interpretation help.

[kaskin]

Need a little help deciding what loads to pick from on the ladder test. I’m thinking 44.5-44.8 gr varget in .1 increments to find the winning recipe?

REM700
1:12 20” factory barrel
lapua brass
WLR primers

No exactly sure where to go from here.

Any help would be appreciated.

Tough to tell much from 3 shot groups, what velocity are you shooting for?

I would shoot a 10 shot group at whatever charge weight provides satisfactory velocity and see if it groups.

Pick a velocity and run with it….

Well, considering this is a ladder test you are looking for the least amount of vertical dispersion. 44.8 grains looks pretty good.

I figured somewhere in the 2600 fps range. Not married to a velocity really. I would like for them group tight and consistent and let velocity figure itself out… maybe that’s not the right thinking..? Not sure

Based on the evidence presented the 44.2-44.8 is where I would look into more like you said

Yeah, and I'd say 44.5 to 44.8 even though that "flyer" on 44.5 might be from who knows what. I would have shot another 44.5 round to see if that "flyer" might be shooter error. This is why I load up more than 3 for each powder charge (like 5) in case I see something in one of the 3 shot groups that I can't explain. And though 44.5 -44.8 look good on the vertical, it needs to be verified with another trip to the range, no matter which load one thinks is "the one." It's all about being able to repeat the results one is after.
