6.5 Grendel

D
I tend to run a stiff nylon brush in and out of the necks and that helps. I use the one's from Brownells and I chuck them in my vice milling machine on medium speed (Milwaukee Holeshooter in my vice).

Since I have the time and the tools, I anneal every time and also use mandrels so my necks are as close to the same as I can make them. The stiff nylon brush helps me get consistent seating depths across many calibers. I also use Forster Ultra Seaters (you love them or hate them) and give the Co-Ax handle a nice slow pull and let the cartridges dwell for a few seconds.

Is every loaded cartridge the exact same? No, but I will measure every 5th one and get about a .0015" variance. I either jam or jump depending on what the gun likes and I am either .012"ish in or .020" out so the .0015" doesn't affect my groups.

I also have never shot anything heavier than 123's and have been in the Grendel game since 2010. My absolute favorite bullet is a Berger 120 BT and since I haven't had any of those for many years, the next favorite is the 120SMK. Not sexy by any means, but they are the butterface of bullets as the target is the only arbitrator.

@jpp3g i don't know how yours is, but i was also really impressed with how tight my upper and lower fitment was. then again, i had always frankensteined my AR's so i had never really had a quality, matched set before. but i don't think i can go back now.

@Cold_Bore_88 i hadn't heard of Icon until your post - i expressed interest in their monolithic upper via their contact form and they called me on the phone (very cool). it is a true monolithic upper that's going to ship with a titanium barrel nut and a essentially really long socket. the first releases will be short-ish handguards this year but he told me they are considering doing a 15-16" with integrated arca rail once they get the tooling. hopefully more people hit up Icon and express interest, i'd love to see this sooner than later.

I really liked the Mega uppers so I would love to see the ICON bring the 15” ARCA version.

What's the deal with "Aid to Ukraine?"

Since the war began, we've spent less than 3% of our yearly allotted defense budget on assisting Ukraine defend themselves from a neighbor intent on fulfilling the restoration of a rotten empire, capable now only of conquering land it can only occupy after completely killing or displacing its inhabitants through a sheer volume of expendable dumb munitions and army of expendable meat waves. That defense budget, which to some people is a totally misunderstood principle, exists to cement our ability to protect and project our ability to enforce our will at home and across the globe. This 3% of the defense budget, which is less than 1.5% of our total budget, hasn't resulted in increased taxes or required funding being pulled from other sources. We've offloaded, replaced and upgraded expired and expiring munitions, vehicles and aircraft, spun up our ability to mass manufacture the aforementioned that did, in fact, create thousands of jobs, maintained our defense manufacturing base and stimulate our economy. Aid packages have been pushed through the unilaterally, as using the money set aside to counter and crush our hegemonic, economic and ideological adversaries while expending exactly zero uniformed American lives is pretty fucking obviously a good expenditure of our defense budget. As of April 18, 2025 our return on investment has been confirmed through verifiable OSINT:

Tanks destroyed: 2838, damaged: 158, abandoned: 388, captured: 533.
Armored Fighting Vehicles destroyed: 1637, damaged: 36, abandoned: 113, captured: 273
Engineering Vehicles And Equipment destroyed: 386, damaged: 48, abandoned: 58, captured: 154
Aircraft destroyed: 122, damaged: 17
Naval Ships and Submarines destroyed: 21, damaged: 7
Self-Propelled Artillery destroyed: 752, damaged: 49, abandoned: 7, captured: 109
Infantry Fighting destroyed: 4568, damaged: 154, abandoned: 465, captured: 629
Trucks, Vehicles, and Jeeps destroyed: 3193, damaged: 104, abandoned: 52, captured: 582

Wow. The propaganda is strong with this one.

Tell me what the response would be if Russia set up 40+ biolabs, was pumping money into the government, had a large number of KGB influencers working with the government, supplying weapons and dangling an invite to join them with the promise of protection to Mexico. Then Mexico amasses troops along the border and claims that Texas, Arizona and New Mexico still belong to them and start shelling them when they tell Mexico to get lost.
Do you find it funny that Russia is bad because they "invaded" Ukraine but it was righteous when the USA invaded Afghanistan, Iraq and multiple other countries?

Is my custom 457 Barrel a dud?

T
I wouldn't give up until you try some other brands IE Lapua/SK or RWS. You just can't predict what the barrel will like. You may just end up lot testing whatever Lapua you can get on your own.

I was recently testing a wide variety of ammo in my T1x. Wolf Match, Eley Club, Target, Team, Target, SK Standard+, Pistol Match, Rifle Match, and Lapua Polar Biathlon. Overall SK/Lapua outperformed Eley for me, although Team and Tenex did almost as well but were less consistent. The 10 shot groups out of my stock 20" T1x varied from 0.9 MOA to 1.5 MOA, with the best performing being mainly around the ~1 MOA mark. There were still occasional fliers even with this.

I would be disappointed too, but give the barrel a fair shake with at least some SK Rifle match before giving up on it. There is so much statistical noise and variation with 22 LR it is maddening.

In terms of lot testing, a friend of mine did the Lapua testing in AZ. He settled on Center X for his Vuduu. It seems to shoot at least a little better than my T1x... But not as much as you would think

It barely got past 360k feet and didn’t achieve escape velocity. Big difference between a ballistic flight and an orbital flight. All these bimbos did was get above the magic “astronaut line” at 50 miles on a ballistic flight, you get a brief period of weightlessness on the parabola….

Not sure their capsule would “get” scorched on re-entry because it barely left the atmosphere and was going WAT too slow for friction to scorch it.

IIRC you have to hit 50 miles or just over 80 km to get astronaut wings. That is far below the 17,500 mph that is needed to achieve escape velocity/orbital trajectory. According to the Interwebz… blue origin was going just 2,000 miles per hour.. or Mach 2.6.

Concord goes at mach 2+ and never scorched the paint… and it was 1960’s technology.

Mach 2.5 doesn’t scorch things like an orbital reentry from 17,500 mph+.

I still think the whole thing is BS… but not because of scorch marks.

Besides, these are women. They should know how to use a hot iron without leaving scorch marks….

Sirhr

To add one more perspective… the German V2 rocket flew the same height. Carried an explosive payload of 1600 lbs (not counting the nose cone itself. And was done with 1940’s technology. This was a publicity stunt. And I would not put it past them to fake it all. But they didn’t have to… except to protect the lives of 5 bimbos. This was backyard garbage…. Not even close to what SpaceX is achieving!!!
