What is a guy with a mousegun screen name doing with a .50 BMG?Great shooting.What kind of rifle and scope do you have?

The AR-50 IS quite a rifle! Mine will go sub MOA with almost any projectile and, like yours, around 1/2 with the A-Max. Haven't tried the Lapua yet....looks like they shoot well too.
Good shooting!
Good shooting!

So pardon me for a slight rant. Yesterday I was at a range with a few friends. I set out my steel target at what was later laser rangefound to be 211 yds. I'm shooting a .308 Winchester. While I'm setting out my target (which is friggin heavy), another group of shooters roll out their gear and send down a couple of folks to set their targets. Firstly, this is a "common use" area in a national grassland so there aren't any lanes or delineating features. That said, I was 200+ yds downrange and they decide to set their target at 100yds DIRECTLY IN LINE WITH MY TARGET. So much to my frustration, I'm left to move my target significantly off to one side to avoid having crossed/ overlapping shooting lanes. So at this point I'm not impressed by their range manners. They then produce two .50 Cal rifles which they place on portable benches. For the rest of their range time, the shoot thier target at 100yds with the .50's, they never announce when they are going downrange they simply set down their rifle and start walking. Then when they are done shooting one of them comes over and asks if he can borrow my 2 wheel cart so he can get his "100 lb target" from downrange with it! I decide to be gratious knowing that it will only hasten the departure of range jerks. When they get their target back to their truck they announce that their target is 1" thick and DESIGNED to be shot with armor piercing ammo! Sure enough they made huge dents in the steel and succeeded in blowing the mounting bracket off of the target (which was the real reason they were done for the day). So needless to say I'm glad to read that 5.56 set thier target at 200 yds AND that armor piercing projectiles were not being used. I know it's all a matter of perspective however I'm much less than impressed by rude range jerks who wang away on a target that's obviously too close until they destroy it. In comparison, a friend of mine shot my iron sighted inline muzzleloader from the kneeling postion and made a 211yd hit on my 20" x 40" torso shaped steel target! 5.56 I'd wager that it'd be hard to see improvement at 200 yds if you're shooting that well. My guess is that if you were to step it out farther, you could see the difference from one handload to another a little more readily. Still and all that is impressive shooting!

[sarcasm]What? You shot paper at 200 yards with a .50 and it didn't turn into confetti?!! Well this blows the "even if your round passes within 25 feet of a man it will still rip his limbs off" theory to hell.[sarcasm]
but on a serious note, nice shooting. Wish "my" M-107 could produce groups like that.

Rockstar, when they do things that wacky I'd have to assume that they're not rude, just stupid. This means that they might be open to learning, like range rules, so they don't get shot. If you don't establish basic range safety with them, then it's kind of your fault. They're obviously too stupid, but you have no excuse

Mumbles, roughly what size groups are you getting out of that rifle? The commercial ones I've seen didn't do all that well, comparatively speaking, from what little I saw.

2-3 MOA at 300-500 yds with API

Seems kinda disappointing...10 to 15 inches at 500 yards? 6 to 9 inches at 300? Did you get a chance to use any match grade ammunition in it, to see if that would improve things much?

no, never been given anything other than API and delinked machine gun ammo. I've heard it's not much better with match grade ammo though. The company claims 1-1.5 MOA with match grade ammo, but I'm gonna have to see it before I believe it. I can't believe any decent accuracy can be achieved with a design that fits together so loosely.

Just looking at the target and I have a question: Why is it that no one zero's their rifles ? On most every accuracy group picture I've ever seen, the group is anywhere, except the bullseye. My targets usually look like I put a golf ball through the center of my target. Just curious....

I was with Rockstar.esq that day, and I concur that they were goobers as opposed to a-holes. By the way, he failed to mention my magnificent offhand shooting with my K31, which I find to be disappointing....

TIMBOKHAN MADE MANY MANY HITS OFFHAND AT 210YDS WITH HIS K31!!!
He had a solid 95% hit rate on my man sized steel target. A most impressive show to be sure. Even if he does hold his rifle like a Frenchman...

Your assuming he won't zero it now that he's decided on a load. No point in trying to hit the center with different loads shooting to different POIs in the development stage. Only group size matters in picking a load.
His next step should be zero it (only to ensure a paper hit) and take it out to 400-600 yards and really see what it, and his next best load can do. Confirm load, fine tune zero and be good to go.

You are correct in your asessment of what was going on.
The rifle has shot under 5" 5 shot groups at 1,000 yards. This load is a far better load.
To answer some of the questions.
My rifle is an Armalite AR50 with a 5.5-22X50MM nightforce. The rest I use is a custom Tom Manners.
This load is a easy one 215.1 grains of H50BMG.
Necks turned to .022, Neck sized with a .545 neck bushing.
MY match ammo for each 5 shot string has been fine tuned. The total weight varience between loaded rds is less than .1 of a grain.
Several 5 shot groups are within .05 grains of each other. I use a denver instruments scale.
All my brass is sorted to within 1/10 of a grain as well as the bullets. It is anal, but the results are there. For those of you interwested. There is a 50 cal Match at Quantico 20-21-22, next weekend.

If the avg velocity of your load is hitting the barrel harmonics right, minor charge variances shouldn't matter...like up to .5 grain or more even. I use the "ladder method" for load development (.300 WM) and confirm at 300 yards with a 3 shot group that has a total variance of 1 grain with my chosen load charge in the middle. I got just a hair over MOA at 300 from this group, windy day too. It confirms that my chosen load is exiting the barrel at the peak of a barrel whip. A little slower, or faster still keeps the bullets close together.
I still keep my loads within .1 grain though...
5" at 1000yds is awesome, I haven't had achance to ever shoot at 1000 yet.

BTW,
Just for ****s and giggles. My rifle is zeroed. It is at it's mechanical bottom.
At 100 yards I am +3" at 200 it is +5". My "zero" is a dial in of 2/6/3 on my nightforce for 1,000 yards.
Which puts me on the paper at 1,000 If I dial in 8/2/1 my zero is 1 mile. And yes we do have a 1 mile range here in Ohio. We shoot at a 48" steel plate circle at 1 mile as well as 42" paper targets.
The 1 mile target is humorus to shoot. You fire, count to 4 slowly and then watch for the hit in the scope. LOL Pretty much indirect fire with that arc!

wow, that is really impresive, I got to shoot the M2 and the M240B from the turrett of a moving hmmvee yesterday at ranges going from 75 meters out to a 1000 meter moving target while stationary, almost hit it, lighting was not in my favor (yeah I know, blaming outside factors for my misses) spent a total of 21 hours at the range yesterday. had a couple of guns go down, one 50 had a round go off on the feed throat assembly, twisted the j block all to heck, but it was still shooting like a champ.

oh yeah, they're still putting out that if a .50 round travels within a foot of your head it'll give you a concusion, I haven't heard anything one way or the other, but it seems kind of fishy to me, anyone know one way or the other.

Well, I'd like to think my head is made of sterner stuff than a paper target, and 5.56's paper target is clearly not in tatters after multiple rounds not only passing near it but through it, so yeah, I think it's safe to say the .50 cal passing near you will do horrible things to you is total bunk.
I still hear it on a regular basis though. Anytime anyone sees me pull "my" M-107 out of the arms room, its guaranteed they're going to ask one of two questions, if not both:
1) how far does that shoot/how far can you see with that scope?
2) Is it true that if a round from that passes within ___ feet of you, your ___ will be ripped off?
Edit to add: and when the M-24 comes out, the standard questions are:
1) is that the .50 caliber sniper rifle?
2) can I look through the scope?

Well folks.
The proof is in the pudding! lol
I went to Quantico over the weekend for a Sanctioned .50 cal match. I had good luck and bad luck.
I brought home a 3rd place in the hunter class and a 3rd place in agg group in heavy. The armalite performed well, it needs a trigger job which I will do this week.
Several 10" groups. The best on record fire was as follows. a 6 3/4" inch screamer at 1,000 yards as well as a hard luck group. I had a 3 shot group going well under 3" After the 3rd shot the target frame in the pitts jammed. There were 2 screamers shot, mine was the 2nd smallest group over the 2 day match.
It was 5 minutes till I had a target to shoot to finish my string. The barrel cooled and the wind changed. Opened the group up to a 10" group.
Such is life! But it was a learning experience. The 6 target agg for heavy gun was a 14.00 First place shot a 12.25"
6 target agg I shot for hunter was a 16" group I am not sure what the first place was, hunter is based upon score not group, there was a tie for 3rd place and then group settled the tie.
Back to the reloading bench to get it cleared and tear this rifle down and see if I can get the darn trigger down to about 1LB

Sorry to get off topic, but...
How do you like that night force scope? I'm thinking of getting one for my long range Grendel set up, but was worried that the 5.5-22X50MM might be too much magnification. Any thoughts. Maybe the 3.5-15X50?
Thanks... We now return to your regularly scheduled thread.
