Thread: Best/simplest alternative to a ladder chart?

So here is a OCW test shot on Sunday last. Conditions were practically perfect, just a bit of mirage which we seldom encounter here, off a pretty good benchrest at 100M. I always shoot a group with another rifle just to make sure I'm up to the mark . . . . And yes I'd say I was shooting 0.5 MOA or better.

The rifle is a new Bergara B14 extreme in 223, I saved up for a good while to get one of these, so despite it being a "middleweight hunting rifle" I have/had fairly high expectations of how it might shoot. It's had about 50 rounds of factory ammo through it to start a bit of a break-in process, and I'd usually try for about a 100 normally but wanted a picture for this thread.



So a 18" barrel 1:9 twist 223 with Hornardy bulk 55gn projectiles. Brass is once fired hornady, powder is 8208, Garmin chrony. Target is shot "round robin". I was a bit reluctant to post up this target initially (until Puffins posts) because I thought it would possibly confuse the OP. It sure confused me (although my ego was stoked by the 25.1 group) until I recalled the "statistics and dammed statistics " of 3 shot groups. What would you guys do next?

If I wanted it ready for the weekend I'd load a bunch more at 25.1 and be happy until I got home again

Then if I hadn't run into pressure during the outing that produced the groups above, I would probably (definitely) load some more charge weights going up in the same style until I did. See what that looked like and go from there.

Or tune the 25.7 load with seating depth.
