re: Sighting in Rifle Question(s)

Everything on the azz-end looks fine. All case heads have a portion where they’re a little shiny, even lower end charges, but I haven’t been attributing that to excessive pressure.
I was not wrong that I won’t be able to get to the Barnes max. But it’s as likely to be a sheer volume limitation as much as a pressure limitation.

Why? You gonna burn up powder and primers going in .2 gr increments till you get sticky bolt?
What I've learned in the past year is that going for a magic number is a waste of components. Pick the bullet you want to use, pick the powder that is slightly compressed at book max, find something good enough, load a whole bunch of them and go shoot.
If you fly to close to the sun you might get burned by a sticky bolt on a hunt.

Not trying to be a dick but it sounds like your rifle has something seriously wrong with it or your pulling the trigger from shot fatigue on the third round. The 308 has some long distance issues but if you’re siting it in at 50-100yrds the groupings should be tight even at high winds and extreme temps.
Maybe consider trading it in for a 270?

All 3 were sub 1” groups, but the 48.2 was noticeably the best. All pretty little triangles. Not too trusting of 3-shot groups, though.
I guess I’ll keep creeping up. Would really like to be over 3k.
Have you figured out why that 3rd shot was 5in out the first time?
Don't worry about 3k velocity. The paper or the animal will never know the difference.

I did a neat lil experiment working up one of my rifles. Shot every bullet from starting load to max at the same bullseye. The result was one 1.5" group with like 15 shots in it, and basically the charge didn't matter much except for speed.

I’m not the OP. None of mine are 5” out.

I guess that is the crux of what I'm trying to figure out and if anyone has also noticed this with a 3rd shot flyer.

Load development is mostly BS. I get competitive shooters look for every edge but the majority of people should pick a bullet, brass, primer, and near max load and go shoot. If 10 shots are under 1.5 inches you can shoot that load for the life of the rifle. If it's over 2 inches change bullets or powder.

Clearly you are experienced in a very select part of reloading.

Here's the deal with load development or ladders shooting 3 shot groups: It's not repeatable and you'll burn through components chasing your tail.
10 shot group and if you're not satisfied change bullets or powder. It's really that simple.

Like I said you are experienced in a certain type of reloading.
What are your reloading steps? That could have a lot to do with potential inconsistencies you are seeing.

Size, trim, prime, powder seat
There's no inconsistency. It either shoots or it doesn't.
I have neck dies, bump dies, FL etc

Well that explains a lot!
Annealing is probably the most important step to getting consistent loads. No wonder that is your mentality.

I think I’d get something similar if I did more testing with the stuff I’m currently playing with. If I overlayed the 3 3-shot groups yesterday, there’d be 9 holes inside 1”.

Not really. Using once fired in your rifle would be the most consistent.
My mentality is you do whatever makes you feel better. Post a 10 shot group. If all that annealing and extra you're doing makes a huge difference prove it to me.

Great shooting. I'd think if you shot each seating depth 10 rd groups you find that they are similar using the same powder charge. The rifle and you are accurate though no doubt about that.
You're shooting under half inch with 7 shots. 10 would be maybe half?
What bullet are you shooting? I have a proposition for you.

Annealing brass is a very important step if you are wanting to shoot competition.
I have brass that’s been reloaded 18-20 times (Lapua).
If you do not anneal, the brass gets harder and harder after every shot. Annealing softens the brass.
I also turn the necks when it’s new (competition brass only).
