    25x47 Lapua load data

    If they haven't gotten a new one or changed reamers in the last couple of years, that'll be the BlackJack spec

    Vortex Impact 4000 Giveaway

    Found this giveaway for an Impact 4000 while scrolling the social media. Seems to have very few strings attached. Thought guys might be interested in it! https://woobox.com/3d85fs

    Ragnarok Sniper Challenge?

    How was the match in terms of stages and movement between them? I don't recall seeing anything about movement distances, time hacks, engagement distances, round count, etc.

    Coup De Grâce, New Action from American Rifle Company, $899 WOW!

    Yeah, my SA .473 order is from the end of May. I figure we've got a bit of waiting to do still

    Coup De Grâce, New Action from American Rifle Company, $899 WOW!

    Shipments haven't stabilized out enough yet to tell. Guys are getting theirs that were ordered in February. Haven't seen anything from an order date later than that yet. It's a game of catch-up for ARC at the moment. We'll see if I get mine in November.

    25x47 Lapua load data

    My current load for 25x47 is with 131gr ACEs. 39.5gr H4350. 2820 fps from a 23" barrel. GRT matches up and puts me around max pressure for the x47 case (63091 psi). As always, take it easy because the x47 case generally doesn't show typical pressure signs very readily.

    18 inch gas gun 308 vs 6.5 creedmoor

    16" barrel, midlength gas, gas port somewhere around .080", A5 length buffer tube, H3 buffer, full weight BCG, Springco Red or Tubb's SR-25 spring. Make sure the gas tube ends in the middle of the can pin cutout (not short) and she'll probably run. Mine does

    Ragnarok Sniper Challenge?

    Did anyone shoot the Ragnarok Sniper Challenge in 2022? Looks to be a "Mini-Mammoth" in Minnesota. I'm interested in doing a field match of the like with some guys of mine and wondered if someone had feedback on this event.

    Drop in AR308 barrel

    I've had good luck with X-Caliber barrels, though not specifically on large frame AR's. $365 is their starting price point.

    CMT Barrel Nut Wrench Alternatives

    Used handguard, I didn't have a typical box, lol, but I'll send them a message and see if they can do anything for me!

    CMT Barrel Nut Wrench Alternatives

    I've tried my BCM castle nut wrench, it's too small of a diameter. The barrel nut diameter is 1.520". Maybe one of the single tooth castle nut wrenches would work in a pinch, but I guess I was hoping for better than "in a pinch."

    Very cool, thanks for the replies all!

    Thermal Science Question

    So, this is gonna be a really dumb thread and it will serve no real purpose other than satisfying my curiosity. I had a thought this morning while sitting on the shitter: could you feasibly detect if someone was carrying a concealed handgun from afar with a thermal device? My thought process...

    Chasing Gear, the broken record of shooting lighter calibers

    Maybe not exactly the same circumstance because 175gr isn't heavy for 30 cal to the same extent the 85 or 90gr bullets are for 22 cal, but it reminded me when I tried going down to 155gr from 175gr when I was shooting my .308. Inside, say, 500 yards, speed was 100% my friend, and those 155's...

    Are My Expectations Too High?

    Alrighty, here we go! Bought some IMI 77gr Razor Core and headed back to the range this afternoon. Not the greatest range setup, but it'll do in a pinch. Sat down, warmed up with some dry fire; everything is awesome. Reticle isn't moving when I break the trigger, position feels pretty comfy...

    Are My Expectations Too High?

    The BCM is pretty slim internally. Around where the gas tube goes into the block, I'd bet there's only about 3mm of clearance either side, maybe less...
