Pull the BA and sell it.

Buy the 18" criterion.

Move on with life.

If weight is primary concern I will go this route as well get the 18" criterion.

If it works, it's not stupid. I've got a normal shaped face and that would be a jaw weld for me.

Headspace: the distance from the breech face to the point in the chamber that is intended to prevent forward motion of a cartridge.

I’m not seeing any evidence of there being a headspace problem.

Your primer blanking is from excessive firing pin aperture size on the bolt.

Notice the nice round edges of the primers.

Your rifle is ejecting at 3-4 o’clock, shooting ~ MOA, and working.

What more can you ask for with an Aero .308 DIY build?

Consider yourself blessed.

Maryland: Ship hits Francis Scott Key Bridge causing it to collapse

A ship has hit the Francis Scott Key Bridge in Baltimore, Maryland, causing it to collapse, authorities said.

Pretty dramatic collapse. I honestly don’t suspect anything nefarious…other than laziness and/or ineptitude, but this really sucks from a variety of angles, as mass casualty events are by definition I suppose.

Not the least of which is that Uncle Potato will definitely bail out his voter base and put all American taxpayers on the hook for a replacement. At least it’s $$ not going to Ukraine, or to study the sexual proclivities of central asian frogs or some other such nonsense.

Epic! I can’t wait for that to show up on CNN!

I'm using a Bergara BXR for positional training. It's cheap, accurate, and fun. Building another rifle just for training purposes would be a huge waste. I'd rather just buy more barrels.

How many here know who Francis Scott Key is?

A %^*+#ing bloodsucking lawyer who was hiding out during a naval shelling then sampled a British barracks tune against copyright law when he should have known better, re-wrote the lyrics, and then pocketed the royalties from his little ditty for the rest of his life before it became our national Anthem more than 100 years later when the copyright expired.

You mean him?

Follow me for more “real” History they You thought you knew from 5th grade.

About 15 or so years ago the Mississippi River was very low. It was preventing coal barges from docking at unloading ports along the river. Guess where all the eastern coal power plants get there coal from, yep down the Mississippi. The whole eastern US was only a few days from going mostly dark because all the coal plants were fixing to run out of fuel. That fun fact was never made public for obvious reasons but plans were put in place to prevent it from happening again. I’ve always told upper management that the real threat to the “grid” is in the fuel or lack of. What would happen if most bridges across the Mississippi River were to suffer the same fate, no shipping traffic up and down the river and the east cost becomes almost an island. There aren’t that many bridges across the Mississippi. And whoever said they will have that bridge back up in no time is dreaming in the same way they said the Ukraine war would be over in a couple months.

The gun is already at 14lbs+ with scope.

There are people lugging around 16-18lb semi autos on this site.

I would shoot it first.

If you want lighter weight then it's a bit of everything. Different stock choice, shorter/lighter barrel, lighter scope mount, lighter optic but it won't be as fun to shoot off a bench or bipod.

So one of the best loads I’ve developed is the 77 TMK with XBR-8208 with REM 7.5 SRP in Winchester brass. I found this particular load shortly after I built my Bartlein barreled precision AR. Over time, I’ve refined it, and also worked it up for LC brass. The loading in LC brass is my standard HD load and the one I zero all my 223/5.56 rifles to. It shoots great in every rifle, and my 16” Proof AR shoots it in just as small of groups as the Bart.

I also seem to have a good amount of PMC and PPU brass that I never seem to have a good use for, so I decided to see if I could rework it for the TMK+XBR combo.

So I weighed some of my brass, which was all wet tumbled, resized, trimmed, chamfered, deburred, flash holes uniformed and primer pockets cleaned & crimps cut out. Average weights were as follows (weighed on my AD FX120i):
LC- 92.0 gr.
Winchester 223 - 92.9 gr.
PMC - 92.4 gr.
PPU - 94.9 gr.

My LC load is 23.8 gr, and the Winchester load is 23.7 gr. I tried the charges in the image below… very happy with the PMC 23.8, as it’s right there with the LC loading… which makes sense as the brass weight is very close to LC.

I think the PPU just has too little case capacity and it doesn’t quite work in this 5.56 pressure range.

Anyway, fun little experiment. Don’t let anyone tell you the 77 TMK can’t shoot tiny groups! (target shot at 100 yards on my private range)

I’ll take it per our conversation.

Looking into the above.

We have a few panels on our boat. 4 to be exact. 1 is dedicated to the battery bank "charger and de-sulphater" circuit.
1 is situated in the cabin, at the helm, to which there are 2 USB ports as well as a 12v cable hanging off it. We usually leave this one on the dash in the direct sun, for whatever electronicals we want to charge. I charge my coffee grinder off it, each morning. (right handy piece of kit, that one)
2 others we have mounted to the handrail at the bow, and are dedicated to the "Ukrainian Air Conditioning" that I'd created. It is essentially a 'swamp cooler' that uses the temp of the river at about 11-12' below the surface via a "cold leg".

We learned last year, that it'd be better to use a bucket (barrel?) on the dock with dock water and ice blocks in it, because the temperature of the river water that far deep was still nearly the same as ambient air temp. Surprised us, largely.

Trigger pulled on C35 Gen 2. Can't wait to get hands on.

For a large magnum, I'd lean towards a brake, but for a caliber 6.5 or smaller, definitely a suppressor.

Nothing in those pics looks terribly unusual, did you check headspace when you put it together?
