Summary: Welcome to episode #17 of the AR15 Podcast. I’m your host Jake Challand with Co-host Reed Snyder. This is THEE podcast about your favorite black rifle! This show is for you; whether you're building your first AR or you’ve been building ARs for years. There’s something we can all do to take our black rifle to the next level. AR-15 Product of the Week: LaRue Tactical Low Profile Gas Block LT-202 for .750" barrels $69.00 Gun Guy Radio T-Shirts: Order yours here Main Topic: Ballistics Internal ballistics (sometimes called interior ballistics): the study of the processes originally accelerating the projectile, for example the passage of a bullet through the barrel of a rifle Transition ballistics (sometimes called intermediate ballistics): the study of the projectile's behavior when it leaves the barrel and the pressure behind the projectile is equalized. External ballistics (sometimes called exterior ballistics): the study of the passage of the projectile through a medium, most commonly the air between firing tool and target. Terminal ballistics: the study of the interaction of a projectile with its target, whether that be flesh (for a hunting bullet), steel (for an anti-tank round), or even furnace slag (for an industrial slag disruptor). Listener Feedback: Dug Harris: AR-15 Podcast question I recently purchased a BCM AR-15 .556, rifle length (20”). For some reason it has a problem cycling steel cased .223 ammo. It does great with brass. When I say problem, I mean problem as in it won\'t eject the case and strip the next round...ever. What do you think the problem is? Thanks much and love the Podcast. Joe: Next, magazine springs. In 30 years of competitive shooting, collecting and selling guns, and running a small gun company, I have never seen a magazine spring that was too \"weak\" to function. I don't believe springs wear out from sitting in a loaded magazine and will only believe it when I actually see one! I've found magazines that were left loaded for over 50 years that function fine. I might believe a spring could take a set that might impair the feeding of the last one or two rounds in a hi-cap mag, but have not seen it. Gunshops make a good profit on springs so consider the motives... Finally, you mentioned shooting your personal defense ammo every 6 months or so to get \"fresh ammo.\" Ammo ain't fruits and vegetables! I've shot ammo from the turn of the century that is fine and performs as it did the day manufactured. I've got lots of CMP surplus from the 50\'s that is great ammo. I even have a test running. I've got a case of Mauser ammo from WWII. No telling what it\'s storage condition was for the 60 years before I got it. Since I purchased it, it has been in the workshop at my hunting camp. The high temperatures are over 100, lows in the 20\'s and usually about 80% humidity. Three years ago the camp flooded and the ammo was under about 5 feet of water for 4 months. I was going to throw the ammo out, but decided to keep it; I guess it\'s my hoarding problem! I cleaned the sand and mud out of the case, but didn't take the cartridges out of the boxes. I\'m going to shoot a box every summer to see how long it functions - so far, it\'s fine. Myles: With your recent conversation on Canadian gun laws I thought I would chime in on what firearms laws look like in another commonwealth country. New Zealand has some of the most liberal gun laws in the world, but they still suck. Suppressors are commonly available for as little as 50 NZ$. It\'s almost as easy to get Chinese M-14s, SKSs HK SL8s and AKs. The gun registry was done away with, if you want to legally own a firearm you need a permit of some sort, but they are fairly easy to get. However if you want an AR-15 there is only one option I know of, Bushmaster imports some ARs but they are TERRIBLE. They are so neutered that they make California compliant rifles look like a weapon of mass destruction.
