Ya its called the AS50

No, you can fire them from the standing just fine. Been there done it and there's plenty of videos of firing 50s from standing position all over the net.

Firing from the prone is done for precision due to the effects of 28-40 pound rifles on your arms and trying to shoot them from the standing.


As for McMillian 50BMG actions. The actions are still being built but it takes a fair amount of lead time to get hold of one for building a rifle.

There's a reason the bolt action 50s are in US inventory, they are simply more accurate. The Barrett M82 and XM107 are capable of relatively poor accuracy usually around 1.5-2MOA at best(roughly 15-20inch groups to be expected at 1k yards under perfect conditions and no shooter error) even with accurate ammo. General "accurate" rifles, sniper rifles included, are usually subMOA in the .75-1MOA range or better. The McMillan and a few other bolt guns are capable of this level of accuracy with match grade 50BMG while the M82/XM107 is not.

.47 inch group fired from my own personal rifle,

The current record for the longest-range sniper kill is 2,430 meters (7,972 feet), accomplished by Canadian sniper, Corporal Rob Furlong, of the third battalion Princess Patricia’s Canadian Light Infantry (3 PPCLI), during the invasion of Afghanistan, using a .50 cal. BMG (12.7 mm) McMillan bolt-action rifle. The bullet flew for four seconds, and dropped some 150 feet. The previous record-holder was U.S. Marine sniper Carlos Hathcock, who achieved it during the Vietnam War, with a kill at 2,250 meters; he had 93 confirmed kills. The deadliest sniper in the world was the Finnish soldier Simo Häyhä, with 505 confirmed kills within 100 days in the Winter War.

yea.

your sight's off at 100 yards clickity-click. Unless the adjustments on your scope aren't that small. Over distances relevent to a scoped precision rifle, that grouping will be greater effected, not even counting wind/sun/terrian adjustments.

WOW, peeps in usa are allowed to own these tank killer? damn

an assassin can take out anyone, helicopters etc. isnt the president a bit worried that his vest cant stop such stuff?

When testing loads for groups, point of impact doesn't matter provided you use the same point of aim.

As for the issue of dispersion...

The reason for shooting at close range is to get an idea of what the rifle is capable of for the hopes of being able to hold the groups at longer range. That 100 yard .47 inch group is about the same as you can expect at 200 yards, many 50BMG shooters find that the bullets don't even "goto sleep" until around 200 yards due to coning motion of the bullet.

As for my abilities to shoot at distance?

Here's a 100 yard group from my 300WinMag,


Here is the same load shot at 800 yards in a left to right wind requiring 5.5MOA of windage. Yes, it's still a sub-MOA grouping that you can almost put your hand over. Hold a 5 dollar bill up to the monitor for comparison and scale.

The 50BMG is not that impressive in my opinion. First off it is not some "tank killing" round. I have a 1 1/4 inch mild steel plate and with 700grn AP bullets it has only managed to pierce it completely 4 times out of around 40 impacts. Compared to my 300WinMag with 163grn Ap bullets which has managed to pierce the plate only once out of 15 shots, the ratio is comparably the same.

Most 50BMG is rated to only pierce around 1/2 inch of actual armor rated hardened steel. Something it can only do to roughly 500-600 yards before velocity drops off enough that the kenetic force falls to a point where it will fail to penetrate.

Firing the round to long range is NOT easy, just because it is a bigger bullet does not mean that it allows for a person to forget or not take into consideration wind/trajectory or various other things. In fact to be able to shoot it much beyond 1200 yards you have to make use of special scopes, scope bases, and be quite experienced in shooting to long distances.

But yes, we are allowed to own them in the US. Barrett originally made the M82 for the civilian market and the success was such that the military picked it up. I never really wanted one until California decided to ban future sales of the guns within the state so I finally picked one up. "cheap" ammo costs me around $.85-1.25 a shot to handload. If I wanted to buy the stuff from a local gunshop it would be 2.50-3. bucks a shot. "Match Grade" ammo costs me anywhere from 1.25-2 bucks for the bullet alone before any powder, primer, or the cases.



Lastly, it's guns like this that should keep the politians on their toes. The 2nd Amendment has nothing to do with hunting or sport. It's meant to give the civilian populace teeth to bear against an agressor or a corrupt government.

50BMG bullet holes are 1/4 the size of a nickle? What Grain were you shooting. I had to go to the range to compare but I wasn't able to shoot anything above 300winmag that made holes that small.


IS UGLYGUN Maveric back from the banned?

If you were to read the test target, it clearly states what it was, Hornady 750grn Amax. As for other bullets I shoot, 800grn Lapua copper solids and military surplus 700grn M2 AP for plinking.

If I can find the original test target I will post pictures of the group next to the actual bullets. The imprint left by a bullet passing through a target is rarely full caliber due to the way the paper is pushed back as the bullet penetrates. Only with handgun "wadcutter" or "semiwadcutter" bullets do you get nice clearly defined holes, makes scoring easier, that are full caliber with perfectly cut edges. The actual black marks on the paper may only be .4 inches in diameter from where the majority of contact was made with the bullet before folding out of the way.



But I smell doubt so I will do what I did for a person on the Planet Battlefield forums some time back...

Sorry I wrote the wrong Dev name down, Wraith, these are for you...






And yes, 50BMG bullets are smaller than a nickle in diameter. Not sure what country you are from but try measuring one. 50BMG bullets are .510 in diameter.
