Wow, didn't see this coming.Shooting a Semiauto, don’t sweat the small stuff. You’re not competing in registered BR matches, so don’t let yourself get distracted here.
There is nothing in God’s heaven and earth, after building and rebuilding LITERALLY hundreds of AR’s for the last 20+ years, which could convince me to ever mess around with jamming bullets in an AR. Dumbest suggestion I have seen in a long time.
Frankly, almost all of the AR’s I have built in the last ~15yrs have shot sub-MOA, and I haven’t done ANY seating depth tuning for any of them for at least a decade.
I also haven’t done seating depth testing nor adjustment as my throat erodes in my PRS rifles for the past 3 years. My 6 creeds have fired sub-half MOA groups reliably from 5 thou off to 140thou off...
Moral of the story, so very, very, VERY much about load precision depends on something other than seating depth. To the point that - even as a precision rifle competitor spending thousands and thousands of dollars per year in competition - I don’t even bother with seating depth tuning...

Effectively, I redo load development at least once per month for my match rifles, as “confirmation” tests before matches. When I shoot the same array of group sizes at 5 thou as I do at 140thou, I know my jump isn’t influencing my group sizes nearly as much as any of the other mechanical or internal influencers in my load. And when ALL of my groups are half of what my tolerance for PRS really could be, well... as I said above, I’m not sweating the small stuff.
I start at 5 thou off of the lands when my barrels are new, and I leave my seater alone for the life of the barrel. No chasing lands.

Good conversation and good posts.
It is Interesting how one group of shooters put value on different aspects of load development and load maintenance as I could never get away with not paying strict attention to seating depth and tendencies that I see on paper.

This is my experience also. If it's not designed for mag length in an AR I learned to walk away from them.

Bullet shape is critical in mag fed guns and I would steer clear of vld designs. Jump tolerant designs wont be as fussy on seating depth and your results reflect that.

That’s why I quit shooting BR and F class years ago (besides moving away from a range with regular matches). It wasn’t fun any more when “improving” was no longer about my ability behind the trigger, and became all about my ability behind the press. Finding a load which stands up at 1/4 to 1/2moa without fidgeting is sufficient for every target we’ll ever shoot in PRS, so there’s no need to keep milking the stone as there is in BR. It’s really liberating.
But I suppose it’s kinda like my grandpa used to say: there are two types of carpenters in the world, one kind who builds things because things need built, and the other kind who builds things to be busy building. I’m just not the latter. Some folks are.

Or having brass surgically clean, turning, reaming, powder charges thrown to the hundredth of a grain…lots of stuff gets paid more attention than things that really matter.
How we get topics that start out innocent enough with a question about uniforming primer pockets and the benefits, then come to find out we are trying to get better than 3” groups with pistol loads at 15 yards.
Why the first thing I always try and determine is the definition of “precision” or “accurate”.

When people start talking about weight sorting primers and bullet pointing I way beyond my element and I sneak out quietly.

I totally understand your point of view, BR to me is mostly old fellas that are enjoying the company of fellow competitors except when the line goes hot, then they want to take your head off.
One thing to consider is the innovative thought and new designs produced are Proven at bench rest, bullets, actions, ignition timing, trigger design improvements, barrels, scopes, etc. the dasher you shoot came from benchrest shooting, the 6.5 guys didn't do it. Im always thankful for people like Alex Wheeler that drive new product s and innovation through br.
Don't get me wrong I have a ton of respect for the other disciples especially PRS. im just not sure where you would be without BR.
Come back bro , we need ya!

I’ve thought heavily about shooting BR, F-Class, and/or Service Rifle again, but I know it will be a few years. I’m coaching 3 seasons now - completely inadvertently - so I barely have time to wedge in PRS, let alone another discipline. Once my boy gets into Middle School in a few years, I should go back to just coaching one season per year, and have a lot more of my life back!
