I am sure that the break in can be done with whatever is available. Many years ago I was given a couple of boxes of WWII .45 ammo in steel cases. In order to shoot them you needed to reshape the front of the exctractor. The steel cased .308 ammo may be OK, but it is possible to get the material on the OD of the ammo on the walls of the chamber. Since the steel is less forgiving than brass, I determined that I would stay with brass cased ammo. Wolf makes a couple of grades of ammo, steel case/brass case Berdan primed, and reloadable brass case. As long as it is non-corrosive and has a brass case, I would use them in my rifles. I have seen $12-$15 ammo that would probably be fine.
The steel cased ammo may work perfectly, but after putting almost $2,000 into a rifle, I will probably not try to save the $.10 or so a round. In the Natchez Shooting Supply flyer, PMC brass cased .308 147 grain ammunition is advertised at $11.99 per box. Federal Premium is at Sportsman's Guide Shooter Supply at uner $17 per box of 20 (Speer Bullets). They also have steel cased Wolf at about $9 per box (240 round bulk pack for $105.00).
Also check Black Hills, I have read a lot of good reports on their ammunition.
For those interested in the Hornady Superformance, I found an article that explains how they get better performance, and how it affects gas operated rifles.
They do have a propellant that has more area under the gas curve, with no more peak pressure than SAAMI recommendations. In the 10T, this indicates no problem, but short barreled guns may have a problem. Better to have an adjustable gas system.
Thanks for this site. I am a POST instructor and SWAT sniper in Louisiana. I have been old school with my system FN SPR for years now. Last year at regionals in Camp Robinson I shot the M110 for the first time. 3 shots 3 hits at 900yds. Needless to say I sold my FN and bought an Armalite Super SASS and put a Schmidt and Bender PM2 5x25x56 on top of it. I just started playing with it and logging shots. Im very happy with its performance. Im looking forward to learning some things from you guys who have been shooting this system.
Welcome Gator3! It looks like we may be asking you for information. I built what I call a SemiSASS. I started with a 10T and added all the SASS parts. So the difference is the barrel. I like it very much, I also have an older AR-10T with 24" match barrel that is getting upgraded. A Schmidt and Bender Scop should be great, the Brits in Iraq used the same brand scope on their "longs", bolt action sniper rifles. I am in Texas, but spend a lot of time around Houma, Morgan City, etc.
Hello all! My name is Kevin. I joined the AR ranks this past Saturday with my purchase of an Armalite AR-10A4. Yesterday I was browsing Armalites facebook page and noticed a posting about the limited run BSNF rifle. As I was prepping my warranty card, I noticed the item number on my receipt didn't match the model I'd believed I'd received (BF instead of BSF). A brief call to customer service with concerns of warranty disputes, provided him with my serial number and he confirmed the rifle as a BSNF with 20" stainless match barrel and NM trigger group! Very happy camper! Now just gotta make some time this weekend to break-in the barrel and see how she does!
ArmaLite has an excellent library at the web site. I think we all agree that the match barrels should be broken in as outlined by ArmaLite. When I got my first 10T there was a note that the owner was a competitive shooter and did not perform any special break in procedure. Since that time failure to break in the barrel properly is listed as a cause of poor accuracy. I did not break in the 24" barrel on the early 10T and it shoots very well.
Welcome to you, Kevin, You are going to like your rifle.
