    My budget is so screwed...
    20180531_112351.jpg

    First step done.
    Looking at KAK valueline barrels,
    https://www.kakindustry.com/ar-15-p.../contract-458-16-inch-carbine-melonite-barrel
    Looks like they have a bolt for around $90 as well. Gonna mill out the ejection port on an upper myself to save a few bucks, and I already have an Odinworks tuneable gas block for it. I may go with a dissipator look with a magpul rifle forend, but not decided yet.

    What I really can't decide is weather to build a carbine upper or a pistol length upper for my SBR lower with this barrel,
    https://www.kakindustry.com/ar-15-p...ls/contract-458-8-inch-pistol-melonite-barrel

    So, feedback anyone?

    I'd go with a carbine sized build. honestly I think 18" with no muzzle device makes more sense than a 16" with a brake. The .458 operates at such a low pressure brakes don't do a whole lot for recoil reduction.
    That said I LIKE the way muzzle devices look on AR type rifles.

    Either way your gonna have a blast with the .458 trust me

    There’s enough gas volume there to make a brake work just fine.

    If it didn't cost $250 MORE dollars for an 18" barrel I'd probably go that route. I don't think I NEED a brake, but muzzle treatment would look pretty cool on a dissipator. My brother just showed me a Yankee hill brake that would look great... I will be building both rifle and sbr uppers, but which one first....

    I didn't notice any difference brake on or off on my upper, could have just been me tho.

    YHM does make some nice stuff!
    I didnt know they had a brake for the .458, should be pretty nice tho.

    The brake is actually for a 308 bore, but the thread size ia the same as the muzzle threads, I'd just drill it through. Yeah its nice, and only 65 bucks. I have a big hunk of stainless steel that might just get thrown in the lathe to make my own though.. We'll see once I get a barrel, and some brass and bullets. Probably gonna have to pick up some powder too. I love this addiction... Er ...I mean, hobby...

    Heh, I see you bought the dies to lock yourself in....

    That's cool you can bore out the brake, gives you alot more options.

    So today I pulled the trigger and ordered two barrels, one 16" and one 8" from kak industries. Also 100 starline brass. Gonna have to get some bullets, I only have a small handful of 405 grn cast sitting around. I am waiting for restock of a toolcraft bcg I found on a deal at Arm or Ally, so when those come in I will pick those up too. Just gotta decide which one to build first...

    Looking forward to seeing your builds!

    Keep an eye out for the nosler 300gr muzzle loader balistic tips, for lighter game those things rock.

    I found a good deal on bolt carrier groups today through primary arms, $79.99 for complete bcg. I ordered two and some gas system parts. Now to pick up some upper castings and forends....

    I have it in spades... Got to build a few uppers for my brothers recently, and I'm building up a few dream guns for myself. Yep, it's a fever all right....

    Pfft fever my butt, AR building is a chronic disease.
    I literally have NO reason to want to do the build I've currently got rattling around in my brain, but I'm still probably going to do it.

    Logic also tells me to do the .450 Bushmaster instead of the .458.....but I just found one of my 300gr nosler balistic tips floating around in my random crap drawer. Scraped common sense soon as I picked it up.

    I'd LOVE LOVE LOVE a .50 Beo AR but even reloaded ammo is just incredibly expensive for that caliber. I just use my 870 loaded with slugs.

    Major cost for the big boys are the cases, be diligent on picking them up and don't run stupid hot loads, and they last a really long time. The big bore AR rounds are basically pistol class loads, so they arnt horribly rough on brass, it's dents dings and loss that accounted for most of my brass expenditures.
    Shooting jacketed bullets can be expensive as well, but good cast n coateds are available at very reasonable prices.
    My .458 shot the 405mbcs pretty well, but I think they we're undersized and leaded up my bore, and brake, something awful. My gas system tho stayed clean.

    Barrels and brass came in, very nice finish on the barrels. Bolt carriers may be here tomorrow if I believe the tracking report, and hitting the gun show for some small parts tomorrow as well. Still need to decide on a forend for the SBR upper...

    Bolt carriers are here! And I got up to cabelas to pick up a few different bullets, some ftx 325 grn and some Berry's 350 grn. Hope the Berry's work ok, they are a truncated single radius with about a half caliber meplat. Should work ok.

    I still need to get a forend for both builds, and charging handles, dust covers, etc. How do you guys feel about the cartridge marked dust covers? I also need one more upper casting and to modify the ejection port so the brass can exit. Lotta little stuff but the big parts are here!

    Ps, I will get pics going when I have a minute...

    the best part about a 458 it will kill anything going any speed and meat loss is not very much i shot a Russian bore with my 45/70 mauser with 60 grains 30-31 with a 405 jsp and no meat loss. wish i could make a copy of the the hunt on the computer to show u guys.

    I have a 10.5” .458 soc barrel sitting on my rack, among 6 other barrels, and I just ordered 3 more this week. The barrels aren’t what I consider to be the problem, it’s the pile of lowers which really gets expensive. I ordered TWO lowers a couple months ago, when they came in, the shop mentioned he’d gotten 5, and they all had sequential serials... I couldn’t bear breaking up the set. But I already had 3 others on hand for projects... plus a trio of unfinished revolvers and a Marlin 60 SBR project action waiting in the wings...

    ARs and bunnies...:)

    I just put the scope on the last rifle and discovered I don't have one in a pistol! I am disappointed in myself for the oversight. I resolve to remedy this situation...

    I am just as impatient as you, I want to shoot these! The funny thing is this disease comes in waves, I also got my bedding compound for my 35 whelen build and a few other small projects, still need to finish my suppressor, and I have two 300 blk uppers I'm doing custom work on

    The next thing on the 458 uppers though is forends. I am building a dissipator on the 16" barrel, and I need to get a rifle length magpul moe grip. I also need to get a bolt on front sight since my Fmarked a2 sight is just way too loose on the barrel, and I don't wand to shim it.
    For the pistol/SBR barrel, I want to run a Fortis REV 2 carbine length grip, but a friend of a friend works there and may be able to get me a cheaper price, so it isn't just money, but logistics to get these finished... I am like a kid at Christmastime though... So excited!

    So got my dies set up, and a few dummy rounds put together, both appear to work in a standard pmag

    And here is where the parts are... Note the nice finish on the barrels. 20180709_215840.jpg Forgive the messy build bench...

    LOL, well you can actually SEE your bench...its not that bad.

    Most of the bullets ive tried in the .458 are well short of mag length, didnt try any 500s, but those i think would likely be the only ones that would be close to running out of space.
