Your freind probably also has a 7 or 9" twist in the AR barrel which will further exasperate the problem. While cast bullets,GC'd and PP'd ones can be shot that fast your freind will find accuracy, especially with the RCBS cast bullet (even if GC'd), very disappointing. Might be damaged trying to get the lead out though.Īs you can tell from many of the replies shooting an un GC'd bullet at that velocity is not recommended. 223 AR-15 will be damaged using the linotype cast bullet? Can he get by just cleaning the barrel after shooting a few hundred rounds at the range? This is not a weapon that will be fired thousands and thousands of rounds.Other than probable severe leading of the barrel the AR will not be damaged. What danger is there that the barrel of the. A gas check was not used due to lack of availability of correct gas checks. It appears that load will fire at about 3000 fps. He used Linotype metal and the casting weight is 55 gr. I have a friend who has loaded several 223 rounds using an RCBS mold. (A2 Style AR15.20" with 1/12" twist rate shooting 57 grain CB with IIRC about 21.5g of Varget.) Among the first of many lessons learned- I'm happy most are through reading other peoples experiences here in the forums 223 load, you wont even see the bullet impacting against anything most of the time- The pop can I was aiming at had burned fragment-type holes in it. In any case, one could forget the literal sense of "vaporizing" and just see it for face value- a way to express the concept of the bullet destructing.ĭon't believe me put together a nice hot batch like as if you were shooting jacketed ammo. Probably more of a mix of having it smear in the bore, spread everywhere once the lead vapor exits the bore, and destruct from centrifugal force on the way to target. Does the bullet vaporize completely? Maybe not. In any case, the only things I've been smoking were two or three small batches of.

The fact you disagree with my statement is just fine. NighthunterNo need to be nasty- really, not necessary. Don't give up but rather learn as you go. With 22 caliber bullets small changes can have great effects. I'd also suggest that you back off on the target velocity and work your way up to it a little at a time. bullet fit in the barell and a GOOD bullet lubricant will help you achieve the goal. At these velocities they will deffinately help. I would first suggest that your friend acquire the proper gas checks. Shooting cast at 3000 fps or close to it can be done. Our forums have a section specifically for this topic, and they've come up with some very impressive stuff.Mind you the cost of gear to get into the hobby of swaging can be on the end of pricey. 223 that shoots in the ballpark of 3k fps are the folks who are into swaging. The best method of getting 3k+ fps out of your AR homeloads? buying commercially available stuff.Īnother option that people have safely and reliably been making ammo for. I've been looking into ways around this for some time.It really seems to me that the best way around it is to not use lead boolits (if trying to shoot above 2k fps). This fact alone has caused me a fairly good deal of frustration. I hate to poop in the punchbowl with negativity, but your friend will very likely find that with a load appropriate for about 3k fps with a 55 grain linotype will vaporize the bullet/cause self destruction.
For this reason people shooting with a silencer prefer subsonic loads, even when shooting a rifle.Something you might find useful Click "Cast in the. As a side note, if a silencer is attached to the gun it will only suppress the muzzle-blast noise. Subsonic loads do not have this second component of noise.

The noise that shooting makes has two components, the noise of the hot gases escaping the muzzle and sometimes flashing as they hit the atmosphere (muzzle blast), and in the case of supersonic loads the crack of the sonic boom as the bullet breaks the sound barrier. Most rifle loadings are all supersonic, so subsonic loads are specially down-loaded to stay below the speed of sound. In 9mm, most loading data are supersonic. All data in this caliber is subsonic but is not normally tagged with the name subsonic. Not all "subsonic" loads are noted as such in the data, because the cartridge is not capable of producing supersonic velocity. Subsonic loads refer to those whose velocity is less than the speed of sound.
