There can be plenty of information on min sample ladder tests. Statistics are nice but the target is King. A fella needs a steady/solid set up and test while using wind flags then trust what you see on paper.
What's the difference between 44.0 and 45.0. They look identical...Here is a ladder test, 45gr seems the best of course so my query would be how small a powder increment would yall use to close that up a bit? I don't hunt, I only chase the cloverleaf. Mind you I'm old and my shooting skills have diminished but I still keep hoping

Same with me. On occasion I might reduce an "energetic" load by .2-.3 grains. I do it as a safety factor, in case I get a powder drop that was a little bit heavy. It gives a small margin of extra safety.If it's a rifle round, I use .5 increments. If it's a pistol or revolver round, I use .2 increments. No real reason. It just seems to work for me.
Seriously? 44gr is considerably larger to meWhat's the difference between 44.0 and 45.0. They look identical...
Don’t judge group size while performing a ladder test, similar point of impact is the key. What caliber are we looking at ?Seriously? 44gr is considerably larger to me
Both have two touching and one away. Is that a flier or the operator. Are we dealing with neck tension irregularities, or showing double grouping at both charge weights. Three shot groups are for hunters, paper killers shoot 5 and verify with 10 or more. There has to be enough data to make even half decent analysis. We're the groups shot round Robin to equalize barrel heat and shooter fatigue? To the point of your original question, I'd load 5 round steps in .2 increments and go from 44 to 45. Crono the entire set looking for good SD and es nodes so you can pick a charge for a seating depth test... I also like to run the same test on 2 diffrent trips and compare results...Seriously? 44gr is considerably larger to me
Pistol I go .1 as it generally has a very small load range. Larger pistol cases with bigger load ranges, .2 would probably be fine.Realizing that caliber makes a huge difference I'm curious what your smallest powder increments change is in a fine tuning ladder. I can see how .1 grain change can a difference in .223 but probably not in a .458. In my .308 loads my first ladder is .5 grain rungs and I've been fine tuning at .2gr and sometimes see no difference. So let me ask what caliber and what powder weight do you build your rungs?
