Hello All!
I have an AR 15 with a carry handle, in 5.56/223. I would like to get an upper for it that will shoot maybe a 308 or similar cartridge, for big game hunting. a 223 will just go through a deer and will only piss a bear off, not to mention turkeys. So, any suggestions? My budget is around 500-600, or less if possible. Have a scope picked out, just need ideas on where to look for an upper.

you might want to read a bit on this link and others...

oh and you want a Multi-Caliber lower...

308 won't work on a AR15 lower, it is a AR10 lower...

No sir, he fell into that bullet... Never argue with a stupid person. They'll just drag you down to their level and beat you with experience!!

458 socom

Some guy came into the shop with a .458 Socom upper on his AR the other day askin us about some ammo and what it shot. Now theres a man stopper. Not built for long range of course, but for clearing houses in Iraq, its perfect. Ammo is expensive. Its like shooting a .45ACP round with a bottle necked rifle shell full of powder behind it.

reloading...

Demo, good thing is, if you shoot Hornady, you can reload them to factory specs with factory powder, primer, and bullets for about half the cost of new ammo. My roomie has a Marlin 45-70 Guide gun, it REALLY likes the Leverevolution ammo but he doesn't like the price, so he found someone who will reload to spec and now he REALLY likes the price, and the ballistics are superb.

DEMO is that an invite

to tell you to stay with factory ?
Hey reloads or hand loads can do
great when you find the right
recipe.

see if you can find what's in the factory
loads and match it.

When I reloaded I found some powders
need magnum primers and some
don't. Hornady makes real good
bullets

Demo when I reladed

I had the weight of a box of shells on the wall.
I always weighed every box I loaded.
If a box varied I weighed each cartridge.
You can tell real quick if a cartridge doesn't
have enough powder or too much.

Do you measure your powder or weigh it?
I always weighed mine. You would be surprised
what a difference a minute amount of powder
makes.
I had a room for nothing but loading.
No TV, no Radio, no distractions at all.
Never have more than one powder out.
If you load the wrong powder you get
a boom you don't want.
I'm not preaching to you, just reminding
you,you are dealing with explosives.
You can't be too careful.

Hornady does not have good loads out for 450 bushmaster. They only have the 250 grain flex loads which are still expensive. I am loading 250 grain XTP's (100 box $22) with 2400 powder which I also use for the 460 smith and wesson. I just need to getr better with my techniques. I suppose I could get some better results with the Flex tips.

24 grains of 2400, a compressed load.
Good God the noise.

I'm not up on the 450. Have you talked to any
gun shops or other loaders about a differant
powder ?

6.8

6.8SPC is great for whitetail and similar game. Inside 200yds it would be my top pic for an AR15-pattern deer rifle. The Nosler Accubond load from SSA would be choice of load for sporting use.

.458 SOCOM, .50 Beowulf, .450BM, et al are overkill for most game in North America. The cost of ammo and the recoil is enough for me to save those for hogzillas, Triceratops, etc.

6.5 Grendel is another good AR15 game cartridge, but it doesn't have as many good whitetail factory loads as the 6.8.

As for the price range, I haven't seen any 6.8 or 6.5 uppers below about $700.00. Model 1 and some other AR parts companies offer 7.62x39R uppers for the AR....with the right loads, inside 150yds or so the 7.62x39mm is good medicine for deer and small to medium sized hogs.

Thanks

TX, i was hoping for something good out to about 300-400 yds. I do a little comp shooting, but my 223 is a little ballistically challenged in that area. I heard of a 308 conversion but I can't find it anywhere. That would be about perfect for what I need.

.50 Beowulf or

6.5 Grendel. Check Alexander Arms for more info. Just my 2 cents and agreeing with TXLucky.

CWYale. ive actualy got a similar delema,i know i want a decent deer hunting cal 4 my ar but am a little unsure what to comit to.ive learned 6.5 grendel and .50 beowulf both have special needs 6.5 requires deeper feedramps to match its barrel extension and an enlarged ejection port.i called alexander arms and they told me you can modify any upper to use the 6.5 gren.i didnt get any specs but as there is no material to safely remove on the top side of the ejection port i (ASSUME) that you must remove the material from the bottom side where you have about a 1/8" piece sticking up not touching the bolt carier anyway,but i havent seen one in person or spoken to anyone who has performed the mod themselves.alexander will sell the 6.5gren upper for $100 (they advertise) "can be used to build 5.56/223 cal or 6.5 grendel" and barrel/bolt combos start at $350 then all you need is handguard gas system and bolt carier.beowulf allso uses an enlarged ejection port and special barrel extension,but am unsure of the design of the feedramps on the reciever itself.alexander dose not sell uppers and barrels seperately,just complete upper halves at around $800.saturn machining sells uppers at $130 and barrel bolt sets at around $400-500 i think,but you can also find them on the midwayusa.com website for about 350 a set.i learned from sonju (si defense)my ar manufacturer 6.8 requires no mods to the upper.you can check out sonju at sonju.net they have a large selection of forged gen1(original ar style) billet gen2(improved lower with threaded bolt catch, machined winter trigger guard ect. heavy upper with or without left side rail, no forward assist)or billet gen3(similar lower as gen2 but upper slightly lighter i think,with forward assist,also with or without left side rail) you can purchase uppers and lowers seperatly or as a set.if you already have a lower send it to them and they will match an upper to it no slop with visuals matching lines.all of their recievers com in black, flat dark earth,desert sand,od green,at $20 extra.or failzero perminate dry lubrication coating for about 40 more i think.si defense will also do full cusomization to your specs on their uppers and lowers including rails engraving dimentional changes ect.sonju offers one of the only H-bar barrels ive seen for sale in 6.8 cal for around 300 and a full line of ar10 (7.62 nato/308 uppers and lowers.im still doing research to learn more about what cals require mods to reciever ect and balistics/price for factory amo vs reload ect.lots to learn yet.....hope ive been some help to you.good luck!

But I'm looking more at the BOHICA Arms single shot .50 BMG upper. FWIW, the 5.56 does just fine at close distances on people.

6.5

If 300-400yds, competition, and max accuracy potential is your desire, then the 6.5 Grendel will edge out the 6.8SPC. The Grendel, properly loaded, will give the .308 a run for it's money even out to 1000yds. The Grendel is capable of keeping the bullet supersonic longer than the .308, and has really good sectional density. The 6.8 was simply not designed for use at those ranges and will not perform well. Plus, the Grendel is running best from a 20" or 24" tubes, and you'll be hard pressed to find a good 6.8 longer than 18".

100-120 pills are just fine for whitetail, provided they are of suitable construction.

The 6.5 just suffered a huge blow however....Sabre Defence, who's product I like better than Alexander Arms, is being liquidated. Les Baer makes a terrific 6.5, but it's verrrrry pricey.
