Re: no node
If you are only shooting at 100yds, a chrono will help.
I always look for a load with the lowest ES in the velocity range I desire.
Once I find a load with single digit ES I do a seating depth test and usually that will put the bullets in the same hole,.25" or less at 100yds.
I then shoot at 565 to confirm.
That's how I got the load in the 6.5wssm I'll be sending out to you soon!
In every case with an ES of less than 10 and seating depth refined at 100yds the groups at 565yds have been very good.
3 shots in 1.25-1.5"
Without a chrono I use Jason Baney's technique and try different powder charges, round robin at 565yds at the same target.
I use a sharpie to color the bullets to identify the different loads and look for the load with the least vertical. Once I find it I further refine it with seating depth.
You will find that seating depth is a very effective way of dialing in a load once you have a good ES.
My mom doesn't live far from you.
If you want, we can get together sometime and shoot when I come up to visit her.
