Simple - I look at various reloading manuals and see if they have an accuracy load and start with that powder. Sierra, at least in the past, was spot on most of the time. Lyman and Nosler are also good sources. Sometimes knowledgeable fellow shooters can provide some excellent insights based on their experiences. It's easy to spot the ones that know what they are doing if you observe them and their targets.Thorough reply that reflects your decades of experience, but can you share at what point you select a powder charge, and how you determine it?
its a bit of both. sometimes one can run themselves ragged chasing most accurate charge weights when an adjustment to seating depth changes everything.I have loaded a bunch over the years but, just getting back into precision shooting. When developing the best load for a gun, should you find the most accurate charge and then work on seating depth or, vise versa? If neither of those, what are your suggestions? This will be for both a 223 AR shooting 77gr Bergers and / or SMKs and, a 6BR shooting, most likely, 108gr Bergers.
I start with whatever bullet I found in classifieds and a powder off the shelf that meets the relative burn for cartridge in question.I’m stuck in my ways, I start with a bullet I want to use then choose a known powder to work with.
That’ll never work..I start with whatever bullet I found in classifieds and a powder off the shelf that meets the relative burn for cartridge in question.
Did that make sense?

Might be the best advice on this thread. I start with a constant powder charge and adjust seating. Read Bronsons comment again. I do it with 2 shot groups. First 2 go in the same hole. Next dot shot 2 more see if it repeats. If it does, bingo. Now go tomorrow and if it repeats the same way again, I'm ready.Wear your barrel out at matches, not shooting 5 shot groups to look at.No matter which one you do first, you almost always have to circle back around to it again.
Great comment and I agree with your thought process.Just my 20 m$ . . . . I think a lot of us, as "baby handloaders" started out as the load books directed. Start out with lower charges and work up. Then somewhere along the line we learned that you don't have to use LOA's per loading books. We learned that the bullet's relationship to the lands mattered. So we tacked that on as another knob to turn in a search for accurate loads. It seemed like fine tuning. It didn't occur to us that the seating depth might be a better knob than powder charge. Powder charge first stuck as the way to do things. I know I was puzzled when I first heard to find seating depth first. But fortunately, old dogs can indeed learn new tricks.
Can’t help but notice you’ve stepped up you’re game with the freezer wrap, the target dots are really uptown from my cheap ass sharpie red +I shot this test on Thursday
AR15, 6x45 with 80gr Nosler BT and H335.
Max charge is 26.2gr, I started at 25gr
With a COAL of 2.330.
H335 wouldn't be my top pick of powders but I had it and figured let's give it a go.
Scored the 80gr balistic tips from classifieds $.35 a piece. Lol
Bottom and top left are same depth bottom is sighter spot 2 clicks right for top and start of test moving in .003 increments.
Seating depth was hammered out in 10 rounds 12 if you count the 2 sighters.
Now that it's shooting small I'll investigate powder in .2 increments.View attachment 1653483
By doing seating first it makes reading charge test easier.
Think about it like this...
If your charge and seating are both in a scatter node how can you decipher what your next step is.
Granted some rifles don't like certain bullet powder combinations, and I'm not talking LRBR precision with this test, but I am saying you can grab some random components and put something together that will keep you shooting and for not alot of $$$ invested and still be accurate.
It's a regular grided target flipped over.Can’t help but notice you’ve stepped up you’re game with the freezer wrap, the target dots are really uptown from my cheap ass sharpie red +
