As the title states, I'm attempting to figure out what I need to do in order to legally build a "standard" rifle (by "standard", I simply mean using a full-length ~24" bbl, .30 caliber, single-shot, with sporting-style stock), but starting the build from a bolt-action shotgun action. If the gun...

Hey guys, I am a machinist in my spare time and I have some questions for driving bands as I will be turning my own projectiles for a ~1"/25mm bore cannon. First, can anyone point me towards some good info about the swaging process of applying the bands to the (in my case, steel) projectiles...

I'm in dire need of some help from anyone owning a Savage 110BA, and who also has access to either a Savage 220 or 212 slug gun. I'm starting a new project, and based on the cartridge requirements, the 220 or 212 is actually the more suitable action for me to use. However, I need to get them to...

Hey guys, here's my latest issue; I'm sure many have run into this same issue when using sabots or projectiles with wadding behind them. It goes like this: I have a Chrony Beta Master chronograph which uses typical twin optic sensors like many. I try to put the chrono far enough away to...

I have searched quite a bit for information pertaining to (AP)FSDS ammunition--pertaining to the projectile design specifics--yet I have had little luck finding much. For example, the 25x137mm round would be there most desirable round to find data on, as it's the smallest cartridge which...

I have done some research about this subject, and it seems to end with murky answers somewhere up around 180Ft-Lbs recoil energy and I expect some other results to be added here which may even approach >200Ft-Lbs. At least for what can be proven or even credible based on calculation from real...

I have been filming recoil from my custom 73 cal (12 bore) "rifle" which is a converted bolt-action 12ga shotgun. Cases are custom RMC for chamber. Feed port has been opened and mounts re-drilled--not that I would want a scope on it. Heavy bbl. Ejector modded for long cases to eject. Load is...

So here's where it starts. A friend is given a gun by his great grandfather that was passed down to him. Yesterday, apparently he decides, "I want to sell this" and made a deal to get around $500 for it. I had never saw the gun in person but it doesn't look tough for a smith to clean up...

Most blackpowder poured in a line on the ground burns in a flash. A rifle smokeless powder burns slow in the same test as performed when I was about 10 years old. :D OK, that's a test in open air. Propellants have burn rate coefficients (the rate under steady pressure, like in the open air)...

I have a gun here that is used, it's a Raging Bull. Anyways, I'm not sure if this finish is plated steel, stainless, or what. But it has the satin stainless look of course everyone has seen one I believe. On the bbl, there are a few black nicks down the length, one on an edge. They are not...

Saw these blue 20mm projos at the gun show and wow they are crazy looking. Guy had the bullets on display. Curious: what's the cap on the nose of them for? I notice the core seems all steel, brass drive band, and what looks like an aluminum cap or solid tip. What's the point of the tip? Is it...

I have a question pertaining to who can legally be transferred a friend's two rifles from out of state and who just moved back home. My friend lived in Boston for a little while and had his 2 rifles there. He moved back to Illinois just recently, where he previously owned a FOID card and also...

I really like the looks of this pistol. It's just that the rest of their pistols look sub standard in a certain way, if you know what I mean. These go for $1000. I've never had a chance to see one in person. I'm just wondering if this model is all that for the price, or if I am paying for...

I had been searching for an IR illuminator to compliment my PVS-15 binoculars. I could not find any illuminators that seemed worthwhile for the money as a weapon mount, so I built my own using the Surefire Scout M600. The Scout M600 is my favorite Surefire light--it is slim, lightweight, and...

By looking at the title you are probably wondering who would ask such a common sense question. However, this is just another one of those odd ideas that made me curious. So follow on to see what I mean. For the sake of this, let's imagine a big heavy bolt action bench pistol. If that pistol had...

Case shoulders can be made longer by the process of fire-forming them in a longer chamber. What can one do if a case shoulder is needed to be made shorter? I am shortening the neck of a case by trimming it 0.130". After I trim the neck down, I would like to gain some of the neck that was...

So here is the deal. There were some recent complaints against the neighbors shooting range a few miles down the road. Apparently people hiking heard bullets zipping through the woods by them. This seems to happen every couple of years with their range, and who knows if it is really true or if...

Here is a banner snippet from another forum: I am simply trying to figure out who makes this long M11 upper and lower. Anybody know?

I am currently spending a lot of time in michigan for my job. I read about michigan's open carry laws, basically that open carry is legal without a permit. How does this apply to non-residents? For instance in my situation, I am still a resident of Illinois but was wondering if open carry would...

So would you all agree that the ACR became a failure with Bushmaster taking over the design and jacking the price up? The price on these guns is over $2000. I believe that price is too high. When I type in Bushmaster ACR on Gunbroker, out of ALL the guns, there is only 1 single bid. That bid...
