@@tjrepka5136 you record your stuff? I'd love to see how your stuff turns out. Let me know how it turns out. Keep good records. I have a 7-08 and I'd like to see how things turn out
You're not comparing military ammunition. 6.8x51. They're not using a 150gr Accubond. Or even a 150gr period. Military ball ammunition is 115gr and way faster than that civilian version you got. Plus they're using enhanced projectiles. Just like they did with the 5.56 and 7.62x51 @thewashingtonreloader
Interesting, I would like to see how this performs in relation to 300 magnum cartridges with 180-200+ grain bullets. If this could be done safely and easily, the 308 with this ammo would make most 300 magnums pointless for hunting
A standard bolt will take over 100k psi before failure. Or maybe he should go to a 3 lug bolt like you think with less actual bolt lug surface contact area 🤔. Its great you think sig is icing any better steel on the sig cross or their gas gun bolt lugs. Jackass
I can only estimate based on load data and my velocities. I know I'm below 100k psi of pressure. But I do know what happens when a case is loaded above what it can take. The brass is the first thing that shows you that your loads are getting too hot. No serious signs of pressure. This brass is definitely designed to take the pressure.
Went to 52.2 with exterminator on 125gn tnt had a velocity increase of 267fps over normal safe loads in gas gun . Can't get it to cycle using these cases in a gas gun .a little afraid to go anymore on that need a junker 😂 . Your really sending it lol . I may try in 6mm since I have one of these stupid things stuck in my sizing die now 😢
I haven't tried them in a gas gun yet. I first test in a bolt gun because I know that they're stronger actions. Keep me updated to date on how your testing goes.
Well I'm not having much luck at even up to 52.2 on 125gn as far as cycling ar10 . Its locking the bolt lugs up and jamming the gun to the point where I had to pry the bolt open with a screwdriver.. seemed better on my hottest load . I think the brass is so tough it needs the high pressure to expand the case enough to support the backforce pressure on the bolt lugs . And I'm kinda afraid to go anymore past 52.2 . Maybe ill give it another go when I get the stuck case out of my die or replace it 😂
@@WesternReloader I don't totally agree with that and tungsten is hard to come by. Second to that speed is the only other thing that defeats body armor.
I have 700 hybrid military headstamp brass. Im loading 270-308 Improved, 7mm-08 AI, 6.5 CM, along with a few Wildcats.

Is a different bullet 115gr specifically made to puch through armor.
No. The bullet that I used is also NOT designed to go through armor.
@thewashingtonreloader 6.8 x 51mm XM1186 cartridge, GPA (General Purpose Ammunition), EPR (Enhanced Performance Round)

I will be making some in 180-190 grain for a friend that has a 16" barrel on a bolt gun that he was to get the rounds going 2600-2700 fps. Stay tuned.
I don't know what your pressures are but I'm not sure that two lug bolt is up to the task.I would be checking for cracks before failure.

@Shadytreemechanic77 what is your muzzle velocity? What load data are you using?
That was impressive speeds i did a ladder test with the 169 smk in standard.308 brass and got 2905fps
@@timmcfarland3311 what powder are you using?
Good stuff, I have a few hundred pieces myself. Are you annealing during sizing?
@@harveysexton7176 you switched them to.308? Not yet this is just the first firing. What are you shooting and what have your speeds been?
It’s not the speed as much as the material of projectile…
@@WesternReloader I don't totally agree with that and tungsten is hard to come by. Second to that speed is the only other thing that defeats body armor.
@@thewashingtonreloader right but tungsten at 2700 vs lead/copper at 3600?
@WesternReloader Every body armor video on TH-cam has a vest stopping an armor piercing 30-06. Have you seen one go thru a vest?
