Anyone here have an Armalite AR-10?

[Eric N.]

Just wondering if any of you guys/girls have an Armalite AR-10 in .308/7.62? If so I was wondering what you think about it. I've been thinking about getting one but, I don't know anyone that has one for me to try out. All my friends have various ARs but, they are all .223..

My brother has a DPMS .308 and loves it. He's had various AR's and has one M-16 so he's had some experience with them. I don't think he's had an Armalite though.

My biggest toss up lately has been whether to begin building an AR-15 on the .223 or the .308 platform. I'm thinking .223 but am able to reload mass amounts no matter what the cartridge.

.223 is nice but, I want the added power.. My plan is to turn it into an "all around" type of gun that I could put down a deer with if I wanted to. I think I've already kind of made my mind up about it. I'm probably going to wait a little while though and see what Sig's new .308 looks like when it comes out. I think that they have done a nice job with their 516 so I'm interested in their soon to be realeased (from what I hear anyways) .308 version.. H&K's MR762 looks nice too but, who knows when it will actually come out and it will probably cost a small fortune plus. Also, who knows if it will have more then 10 round clips made for it.

Save a few more pennies and go for the Larue OBR. My penny jar is filling up slowly in anticipation.

Optics cost is a whole other matter.....sigh.

Hey Bill, how are you doing?

I'll have to check that one out too.. It's a grand more then the AR-10 and the Sig but, I'm sure it's going to be cheaper than the H&K, if the H&K ever even gets to the store shelves.

 

[billb]

Doin' OK I guess - nothing newsworthy!

The Larue is very nice in comparison to the others - costly, but nice. The Noveske .308 offering isn't bad either, but the Larue OBR has a few more tricks up it's sleeve.

I'd like one that uses HK or FAL mags, because I have hundreds of them, and really don't want to buy more expensive mags - but is what it is.

Funny you talking about filling the penny jar. I really did take and empty the Water Jug O change to buy my AR15 in .223. The guys at Rifflegear are way cool to deal with.

I bought a remmy 700 tactical for my long range stuff. For the price you can not go wrong.

Brian do you have good luck with reloading .223's? I tried a few years back and that's one cartridge that I just couldn't get any accruacy out of when I reloaded them...

I've reloaded about 500 rounds of .223 for a friend of mine. He hasn't had any misfires and says that he is hitting at least 1 MOA on his shots at 100yds unless he isn't watching what he is doing. He's claimed he can get sub-MOA most of the time.

The issue with accuracy comes with bullet weight on the .223 and your selection of powder. If you put a slower burning powder in, you're going to be more susceptible to bullet tumbles. Using a faster powder and standard to above standard bullet enables you to have more precision at the bench.

I've got another 250 he's having me reload within the next couple of weeks so I guess he likes the reloads.

Now, if I can get Dan to let me get started on his 270 WSM's I'd at least have something to do this week other than my reloads lol.

Thanks Brian

Hey what powder do you recomend for .223 55g Balistic tip?

 

[sean]

Brian, the powders burn rate has nothing to do with bullet tumble. Bullet stabilization is from the twist rate and picking the correct grain bullet for the barrel.

RoverMC, I like Varget and H4895. Varget is the slowest powder I would use and seems to like 55gr. bullets and larger. Both of these powders are insensitive to temperature changes and can be used in .223 to .308 semi's with good results.

 

[brianhoberg]

Sean, I believe we can agree that there are a number of factors that can affect bullet tumble including but not limited to rifling, bullet weight, powder selection, even down to imperfections of bullet seating within the case. However, there are also a number of unknowns that we would have to consider before we went down that road such as how was it reloaded, was the barrel cleaned, is the barrel pitted, what distance was the shooter targeting the target, wind speed, all sorts of factors.
To a long-distance shooter, powder selection would play a role in velocity of the round and as the bullet loses velocity it's susceptibility to tumble can occur. Then again, it coudl be argued that bullet weight was the factor.
I'll say we can agree to disagree and discuss over beers

Brian your right. lead build up, undersized bullets, wrong weight/length for the twist will cause tumbling. If it's tumbling at long range the twist is not fast enough to stabilize it once the velocity drops, yes, you could increase the powder to over come this problem or just use the correct bullet.
As for powder unless you really screw up and load to light or way to hot, it won't effect stability nearly as much as twist rate.

Yes, lets grab a beer one night, I have a lead on a lot of reloading equipment that will be for sale soon.

Sounds good, guess I need to sell off some of those die sets I'm not using while I'm at it. I'll call you this weekend.
Thanks!

Here's the setup I had: I loaded 5 sets of 5 bullets on same loader using same bullets, same gun (almost new). The only difference was the powder amount, the brand was the same and out of the same can. The rifle was a Ruger M77 stainless with a trigger job (by me) in the range of 3lbs. I gave the barrel time to cool between the reps of 5 bullets. However I could never get them to shoot as well as a box of plain old Black Hills HP's 55g. So I'm assuming that it was the type of powder that I was using. And I've got pretty good experience with reloading, mostly from 300mags to 458mags. So any advice is welcome and I appreciate the input from you guys.

 

[roverMc]

Brian and Sean if you make it to GA, I'll buy the beers.

 

[brianhoberg]

.458 as in the .458 Win Mag or SOCOM?Damn, that's a beefy round.

 

[roverMc]

.458 Win Mag - Savage Safari Ed. 450grain SP Bad Ass! Fun to shoot and it's accurate!

 

[sean]

RoverMc post your loading data. Bullet,powder, case, full length or neck sizing, crimp, barrel length and twist.

Edit 6mmBR has some good info on bullet weight, twist and powder selection.
