Hey guys. Loading for a 20. I have load data for WC868, WC870, and OBP-888. None of these are available at a reasonable rate due to shipping. However, US 869 is readily available and I have 32 lbs of it that was nearly free. I know US 869 is a 20mm pulldown, but don't know if it is equivalent...

Hey guys, The 375 H&H AR has been updated with an adjustable gas block and heavier buffer, which has solved the stock breaking issue. Fired a bunch since then, decided it's working satisfactorily, and now I'm planning a .458 Lott upper and barrel. all that really needs swapped is the barrel...

Hey guys. Filed a form 1 for a destructive device. It is permanently in "pending research". Is there a way to cancel and just get my 200 dollars back? Haven't built anything, so there's nothing to de-mill.

Since apparently the 500 Jeffery was much less of a challenge to build than I thought, and EForms has been running well recently, I grabbed some 20mm parts and will be doing the world's dumbest home-built DDs. Have an old Colt M12 parts kit, a full sized vulcan barrel, and a 16" barrel stub...

Hey guys. Newest wildcat cartridge feeds, cycles, and ejects great. It's a shortened 308 case, necked up to .375 that is fired from an AR-15. 300 grain at 1000 fps for a spooky quiet subsonic, or a 200 grain at 2200 fps for a nice hog and whitetail load. Problem is the mags. 223 mags don't...

Hey guys. Got a Savage 110 receiver. Came off a 30-06, has bolt, no mag box, does have the Accutrigger. Despite originally being a 30-06, can I fit a bolt from a Model 110 338 lapua bolt to it? Then thread and chamber my barrel blank for 500 Jeffery? I know that all savage long actions have...

Hey guys. I've always wanted a 318 westley richards or 333 Jeffery for hog hunting, due to the fact that they throw bullets with very high sectional density at relatively good speed, and were designed to fit in a mauser action. Unfortunately, due to bore diameter, neither are very useful for...

Hey guys. I find myself on NECG's website a lot more frequently than I should. Saw a "Mauser 98 Square Bridge Conversion" Looks like just a sleeve that goes over the top of a large ring mauser. Do these just get soldered on? Tig welded? It seems like a neat idea, if I had a spare mauser...

Hey guys. Going to pick up one of the LDA frame castings from Sarco. Mainly as machining practice, but I do want to end up with a functional 1911. Obviously I don't want the weird proprietary swivel trigger. Looking at the castings, they seem to be pretty similar other than width to a real...

The 375 H&H AR is on hold while someone else makes a better gas block than what I was able to do. So in the meantime, I naturally went back to browsing gunbroker on lunch breaks for a new project. Found a 380 Llama parts kit, looks complete except frame and mag. Not the modern Micromax, this one...

Hey guys. Built my 375 H&H AR, now just have some minor work to do before hopefully test firing this weekend. Just need to make a handguard, install detents, safety, and FA, and grind feed ramp a bit. Its a left side, forward charging piston. Handle does reciprocate, as it is directly...

Hey guys. Need to lengthen an ar-10 firing pin by about 3/4" at the back. Was considering welding a bit onto it, or soldering. Opinions? I haven't had much luck making firing pins from bar stock, since they're so damn small, so I'd prefer to just weld or solder a bit of bar stock to the back...

Hey guys. Trying to open up the bolt face on a garand bolt without annealing it, as that would require putting it back through heat treat again. Tried a lathe, but since the bolt face ring is interrupted, it just chipped the carbide inserts without ever cutting. Since it's a hardened part...

Hey guys. Working on a project. Anyone got the dimensions of the Wyatt's Outdoors DBM for ".300"? Specifically the outside length and width, and release tab dimensions. Thanks!

Got an ithaca outside hammer receiver from a friend, who was won it in an auction, but couldn't figure out what to do with it. Has a set of barrels, that don't go with this gun. No stock or forend, but the receiver and internals are complete minus hammers. The screws are all messed up. Serial...

Hey guys. Need to make a pressure test barrel, for caseless ammo. What sensors do y'all use? Only pressure barrel I've ever done before was a copper crusher, which isn't nearly scientific enough for this. I'm fairly familiar with sensor setup and stuff, the barrel isn't a problem, but knowing...

Hey guys. What's everyone's process for predrilling a rifle chamber? I normally don't predrill, but I'm about to do six chambers, and the customer wants them all done with the same finish reamer. To keep the reamer as sharp as possible, for uniform chambers, I was considering doing a predrill...

Hey guys. Got an old sporterized Spanish mauser. Controlled round feed, so it doesn't feed hollowpoints or cast lead. I have no interest in a rifle that only feeds FMJ. Effectively, this means I own a single shot rifle in a mediocre and obsolete cartridge. Was considering rebarreling it to...

Hey guys. About to make a chamber reamer for a wildcat. Wondering about the clearance. In other words, if my cartridge has a base diameter of 0.513", do I cut +0.005" on the diameter for the chamber? For a chamber diameter of 0.518" at the base? If this was steel on steel, that would be a...

Hello, all. Just picked up a J Stevens Model 345, in 20 gauge. Won it in an auction on gunbroker for a ludicrously low price, as a "gunsmith special" Turns out, the only thing that doesn't work is the safety. Everything else is in wonderful mechanical shape. No pitting or rust anywhere, rib...
