    Practicality: 12.5" 308 AR10 -vs- 16" 300blk AR15

    The most PRACTICAL load out there without you making one up yourself would be some mk319. Now isn’t exactly the best time to go looking for and buying some. But there’s your answer based on your OP. That said, you say you don’t want to make up a special load for your 12.5. You’re going to...

    IMR 4064 and 6mm ARC?

    I agree on the capacity issue, but it wouldn’t hurt to try. CFE223 and Varget are slow runners in 6ARC, but then again the most successful powder so far has been Leverevolution...and according to the burn rate chart, it’s the slowest one of all...

    New 6mm Advanced Rifle Cartridge

    Very, very interesting to learn about Lever having use in 5.56 as well. Lever had my curiosity, but now it has my attention. I know the 6ARC temp swing data may still be in infancy, but do you have any data collected on how it’s faring for you in that 20” with 77’s?

    SOLD Do you guys know how to mark your stuff sold? Apparently not

    It’s been the most frustrating thing for the classifieds here. Instead of people just amending their ads once the item sells, they want to pad their post count by bumping it to the top. Now recently, people have been compelled to have their questions, offers, and conversations within the sale...

    Are you able to discern any wear or erosion inside?

    Drilling ACH

    Drill it. RTV the holes and fasteners if you want to ensure it’s sealed.

    6ARC for Small Frame. What’s The Large Frame Equivalent?

    I was referring to what I had learned about the burn rates for the powders. You either had to run the powder with lots of pressure to get the speeds you wanted, or used faster burning stuff that resulted in less than desirable speeds. Very similar to what the case is for 6ARC right now... I...

    6ARC for Small Frame. What’s The Large Frame Equivalent?

    Thanks for putting the .25 back on my radar. I had kind I pushed it to the side since I had reservations of being married to strictly one bullet choice, and the expensive endeavor should a gas gun not like that bullet. But seeing that Berger is jumping in the game, I’m going to bring this back...

    6ARC for Small Frame. What’s The Large Frame Equivalent?

    The x47L’s (or at least their concept) is what I’d had my eyes on for years now, and meant to put that in the OP. But from I’ve gathered from reading about all the loading data and info, they are temperamental with powder. Something about you either have to run higher pressures or run the...

    6ARC for Small Frame. What’s The Large Frame Equivalent?

    Due to lack of projectiles that have an appreciable BC for this use, I’m going to have to say anything 6.8 is out.

    Suppressors TBAC CB for SR25

    Not sure with a Dominus yet, but with the Ultra 7 I was running on 5.56, pressure was significant. I’m used to Surefires and not having to turn any switches or adjust anything when it’s on or off. The Thunderbeast, while on a 100% suppressed setup, made me realize it’s too much for what we are...

    Suppressors TBAC CB for SR25

    I did not. I don’t believe in messing with the stuff in the rear in place of the front when dealing with 7.62 platforms. They are very different than 5.56. Until I have a couple hundred thousand rounds to test - and validate - tinkering with new springs and such, I’m sticking with Knight’s...

    6ARC for Small Frame. What’s The Large Frame Equivalent?

    Since the 6GT in a semi threads seemed to have died off, maybe this will reignite some pros/cons. With the uses and capabilities of the 6ARC in small frames, what would be the equivalent of such in a large frame? Most efficient, all around balance of feeding, barrel life, ballistics...

    Reloading Equipment WTT - 4 lbs H1000 for 205M’s or Wolf SRM

    Located in northwest Atlanta area. I have four sealed pounds of H1000 that I don’t foresee myself using. Looking for Federal 205m’s or my beloved Wolf Small Rifle Magnums. Thanks!

    Suppressors TBAC CB for SR25

    There wasn’t any tuning. The mod 2 barrels simply aren’t compatible, as they aren’t a standard gas system length, nor is their gas port the same distance off the shoulder. While you can dimple it where it lands and let the block float out there, it loses half its support - and sealing area -...

    Suppressors TBAC CB for SR25

    It is, but then you still have the task of addressing the gas issue. So now you devalue a barrel that would pay for the new one tuned for your use... If you go the custom route, pm me first as there’s more to consider, especially if you’re thinking of cloning a mod 2 barrel...

    Suppressors TBAC CB for SR25

    Their gas block arrangement is the best evolution of the system. I don’t have any mod 2 barrels presently, but I seem to recall dimensional differences or something with the threads that made it not compatible with throwing a conventional block on there. I need to measure again to refresh my...
