What's Your Oldest Jar of Powder??
I don't remember powder ever coming in Jars so maybe I'm not that old....but I finished off a pound of unique receently that I bought in 1974 to load 9mm with a lee handloader. Like a lot of the others I've used up pulldown powders from WWII to load 50 cal, and 20mm stuff. I've run through a...- biffj

Gunsmithing Barrel drilling
Only a few years ago we bought 400 blanks from Lothar Walther USA that were 26" long, 1.625" diameter and .311 bore for use specifically with 7.62X54R. The blanks were chrome moly machinegun grade meaning they would handle the heat and wear of use in a machinegun. One of them ended up in a...- biffj

Suppressors Suppressor blew up
No need for flammable material to be used. Anything can be vaporized and thus increase the internal pressure. An ignition is a really unlikely thing due to the reduced oxygen content in the powder gas. This is demonstrated frequently by the muzzle flash that shows up. Most of the flash is due to...- biffj

Suppressors Suppressor blew up
Its engraved because the regs say you have to. I don't know if they would allow a welded or soldered plate but it may be possible. Thick areas and added plates add to manufacturing costs and difficulty so that is probably a good reason why they don't do that part. The engraving problem as I see...- biffj

Suppressors Suppressor blew up
The issue with Hoppes is not so much with Hoppes but with any liquid whether flammable or not. The high temp powder gas will turn whatever liquid is left inside the can to vapor pretty quickly and can increase the pressure by a lot. Water turns to steam and even oils turn to vapor. So if you...- biffj

Gunsmithing What stamp, engrave, etch method do you use to mark your new barrels?
I agree, Laser looks best with an even background and paint is great. I've been using the laser at the machineshop to mark some stuff and it is excellent. You won't regret accepting his offer . . . Frank- biffj

The new 33XC & 37XC cartridges designed by David Tubb
Looking at it from a logic standpoint I can't see any reason your Savage action wouldn't handle it. The max chamber pressure for each is the same and since the 33 and 37XC cases are both based on the 338 Lapua case your area will be the same meaning the bolt thrust should be the same so no...- biffj

Gunsmithing What stamp, engrave, etch method do you use to mark your new barrels?
I engrave the muzzle end with cal and twist on every one I make up using my 3 axis CNC. Customer should know what it is since he bought it but any buyer down the road needs something in writing. Not a big deal to engrave round object with 3 axis machines. Check with your local trophy shops or...- biffj

Suppressors Suppressed 50 bmg?
A lot of it will depend on the can. I built a couple cans for the Desert Tech HTI for some friends. Recoil with the can is noticably less than with the brake. A friend has a bolt action 50 rifle that I don't want to shoot at all with the brake but my can on it tames it down well. Running an...- biffj

375 Cheytac flattening Fed 215s
I've been running peterson brass for the 33XC and so far have no case head separations after about 7 shots in my load workup brass. Some were pretty hot too. I can't see any ring forming inside or out either so I'm thinking its not peterson brass. A good friend has been using the peterson...- biffj

Official (DTA) SRS, HTI, Covert, Hunter Thread
My gen 1 and a number of them that I've worked on and built barrels for over the last 10 years had no issues with mags rattling. Usually the mags were sticky until you got the skins squared away. All the mags in my current gen 1 seem to fit and lock up fine with no rattle or slop. In the Gen 2...- biffj

Will he not use blanks from any other sources? I've not dealt with him at all and I'm asking, not trying to be a dickhead. I am pretty sure he's not making the blanks he's using but some smiths are really picky about what blanks they use. I figure the customer should be able to choose. I may...- biffj

Why would you need to go to cut rifling in a barrel over 26" I've done barrels up to 36" with button rifled blanks. It all depends on the maker of the blanks and what lengths they have available. I got a 33" blank from Schneider for a 33XC finished to 32". A 32" blank from Lothar Walther for...- biffj

Fieldcraft Open tube Boiler done.
Always neat to see someone working on steam power. I built a lot of model steam engines years back and had lots of fun. Amazing how much torque you can get out of even a small model engine on steam. There was a company called Tiny Power near Branson missouri back in the dark ages that had plans...- biffj

The barrel extension uses up .845" of the blank end so you will have a pretty short shank if you start with only 5". Also the barrel needs to be 1.250" diameter plus zero and minus only .001". If its any smaller the clamps will have some issues returning to size for properly sized barrels. A...- biffj

Since I don't and never will use facebook for anything I guess I'm excluded. I'm not alone either. If they can't work with customers who don't use facebook it tells me something is seriously wrong.

Desert Tech MDR Opinions?
I have no problem with the 4140 button rifled barrel in theory. The reality is a bit different though. My MDR had rings all the way down the bore from poor reaming so it wasn't a problem with the material or the rifling process but with the quality of the work. My 308 barrel sucked. I sent the...- biffj
