| Just asking to see if anyone would be interested in a AR that will be avaible in Lefthand and rigthhand models that is cabable of taking game up to Elk and distance up to 150 yards. No modification to the upper or mags. Mike |

When all is done then i will let the cat out of the bag.Cant give my idea away |
What does this do that a 458 SOCOM or 50 Beowulf doesn't do? Seems like you'd be re-inventing the wheel. |

Stop with the tease and give us details! I was working on something like that a couple years ago, basically a 357 maximum rimless with a 200 grain RN .358 bullet. It looks all the world like a blown out .222 Remington. Made up some brass and profiled a barrel which needs chambering. The case base is the same as a .223. You could reload it using .357 magnum dies, and use a 223 shell plate. Everything was to be common except for the slightly modified dies. The 200 gr. round seated to the cannelure is about 1/8" short of magazine length. There were a couple things that slowed me down: 1) The little tab at the front of the magazine lips is made to cam up bottlenecked cartridges, and is right in the way with a straight walled case. I would have to modify each magazine which really takes some of the charm out of this round. 2) Off the shelf rifle reamers for the 357 maximum have a taper ahead of the case mouth. I don't want to buy a custom reamer, and don 't want to modify a new one I couldn't resell. I think I will start over with a bottlenecked round, like necked out 225 Winchester short or a 9x39. |

Well, so far as the re-inventing the wheel thing, I say "why the hell not?" After spending a few minutes with my old (7th ed) Cartridges of the World, I will guess the following: 35 remington is probably not the plan because the case head is dimensionally smaller than the 308, a bit larger than the 7.62x39 and far larger than the 5.56/223, which means that off-the-shelf bolts won't work. So I wonder if our friend is wildcatting a bit.... HMMM, interesting. --perhaps a 5.56 blown out to .358 (a la the 300 whisper?). probably not, I see that the outside case dimension at the base of the shoulder is only .354. You might get away by cutting the case down far enough to allow a .358 bullet to seat, but I think that by then you're out of elk-rifle territory and into sub--gun land. -- An interesting idea might be to take a .308, shorten it a bit and neck it to .358. You would end up with what might be called a ".357 super-auto-mag". -- Another idea would be to try an expanded and re-formed 7.62x39 case. Again, I think that you'd probably end up trimming it down to pistol-cartgridge size, and I'm not sure the internal geometry will allow it. Personally, I like the .308 idea.. plenty of ooommmph and uses off-the shelf parts (except, of course, the barrel). Fun idea though... love to see how it turns out. I'll volunteer for extended field testing. Or perhaps I'm completely off the mark... it happens. |
Lefthanded Thats my main goal i have not seen 458 socom or the 50 Beowulf in lefthand Like i said when all has been tested you will then know. I just want to see if anyone is interested in the round i described in my first post. Thanks Mike |

We have a AR variant section. There are more wildcat and wierd upper lovers over there. www.ar15.com/forums/forum.html?b=3&f=121 |

I talked to JDJones about a 358 size round for the AR and he said there is not a big selection of bullets for 35 cal and bullet peformance is poor with what is avalable. He did make a 358 whisper but the 300 and the 338 had better performance. I have a gun (not a AR) in the 35 cal called the 358 JDJ from SSK and the performance on elk is good out to 200 yrds but at 300 the bullets dont expand. I have tested all of the 35 cal bullets made by Nosler, Siera, Hornaday, Speer and a couple others and found out these bullets in 35 cal dont expand at low speeds. I'am getting 2500 fps with a nosler 225grn BT out of a 16 inch barrel. Good luck getting enough velocity out of brass that holds less than a 223 and keeping the preasure down with bullets that have poor perfomance at the lower speeds you will get. But if you can do it then I want to see it |
Way back when the 357 Herret was developed they used a .358 dia. Speer 180gr Hot-core that works very well on game up to elk in my round i am designing you can use .357 dia bulllets for pistols if you want to load for varmints but i will use this round mainly for deer,boar,black bear and maybe elk if i ever get out to hunt them. Mike ETA: Hornady 35cal 180 gr single shot pistol bullet will work very well also |
Thanks i just posted over there. Mike |
You can not flip the bolt around Stag is the only company that makes a true lefthand upper and bolt,carrier. The only calibers for lefthand are the 223/5.56 and the 6.8SPC. I want a bigger caliber for boar.blackbear and elk so my 35 cal will fit the bill. Mike |
thought about an AR-10 or DPMS .308 chambered for a .358 Winchester (just a necked up .308) |
