For those who take an interest in firearms, this might be the biggest boom-stick around.

Sweet Holy Hell. I know we are really good at making stuff to kill each other with but that beats a pointed stick by quite a lot.

Big gun article guy said: then figure out how to sight in a rifle with an effective range that, with a bullet that weighs almost 4 ounces, is certainly over 5,400 meters

That is, uh, quite the unique problem to have...

The guy that made it must have a really, really small hootus.

So conceivably a 30 inch group at 5 kilometers? Are we hunting helicopters? Ships? Tanks?

What's the shot delay over those ranges?

But a sporting exemption... Hmm... I wonder what the price tag would be in the class 3 market. M16s and RPG 7s run around $45 grand buying from brokers, I'd imagine much steeper buy in, then that ammo cost...

How far can you see? 5k has to be farther than you can see in most places and most days

In reply to Robbie: normally yes. But in certain desert conditions and with a nice high firing position the wimpy .50 cal just doesn't have the reach at a mile of effective range.

10 miles is the typical visible range when they show the fog forecast.

They say that if you're standing on the ground, 5k is about the max before the curvature of the Earth starts to cause problems. That would be someplace totally flat and open like the desert, a salt flat, or open water. If you start from an elevated position like a hill top or high rooftop though, that can be extended a bit.

You can see tall things like skyscrapers and mountains from very far away though. I can see buildings over 15 miles away when I visit my in-laws.

It only weighs 105 pounds, so I expect this to be a weapon featured in Fallout 5.

We are going to have to have guided projectiles pretty soon at these distances.

True. I imagine this .58-caliber "rifle" (more like field artillery piece) requires a spotter with a radio saying "left 3, up 5 fire for effect."

Tell that to the Canadian sniper who made a verified kill at a tick over mile with his .50 in Afghanistan a few years back... Against a walking target...

In reply to WildScotsRacing:

Apparently the ballistics of the .50 cal are pretty bad. The go-to round for the last decade has been the .338 Lapua.

In reply to KyAllroad:

Yeah, well, I'll betcha the .50 makes a bigger mess

There's going to be a Fallout5?

It will come out well in advance of Half Life 3.
