I tried googling but i couldn't find anything.
50's were always designed to send rounds down range. Modern designs had to catch up.
Are they "better" is a subjective question.
As will be your intel on enemy materiel at 1km to 1.5km distances that cannot be suppressed by other means.
If you are needing to get your Special Forces teams that engaged, giving them laser designators and letting terminal guided weapons do the rest. A JDAM or a 250kg LGB is even more effective than a single 20mm round.
Mind, if you can get the SF penetrated in deep enough, a 155mm Excalibur round will reach to 40km (25 miles). That's a 22kg of HE you can shoot into a 1m CEP circle. (MOA at 25 miles is about 4100 feet.)
50 BMG never was a "sniper" round. It works okay because it has a long range and a heavy bullet. It was always suited better to anti-material. It has a big enough projectile to be able to be tailored to a multitude of applications: i.e. ball M2, AP, APIT, HEI etc.
was hoping they would make a .60 cal or a .70 cal!!!
They have in the nitro cartridge... you can have it.
.60 Cal ammo.
maybey when I was 30yo… 45/70 loaded hot hurts me now
If your using a light guide gun I believe recoil is in the 30s. I like my heavy XLR and 1100fps ish loads
my Ruger #1 is not light, but it kicks like a low rider with hydraulics. Yes, tight to the shoulder leaning forward
.60 cal is 15mm; .70 cal is 17.78mm
20 mm is right at .79 cal.
25mm is 1.02 cal
Nothing gets by you Navy Boys!
Makes 50 BMG seem cheap to shoot.
1.00 inch = 25.4 mm
0.60" = 15.24 mm
0.70" = 17.78 mm
20 mm = 0.787"
25mm = 0.984"
Sometimes guns don't use an exact figure, so take it for what it's worth... but those are the basic conversions between inches (caliber) and millimeters. I noticed the 25mm was obviously off, as it's less than an inch. It looks like you just did that conversion backwards. The others are fine, just rounded.
Thou must have not heard of the .950JDJ...
WTHeck?!?!?!?!?!? What’s the parent case? a AT-4? lol
Look up the gun that shoots that cartridge... It's quite comical!
Something more modern with a BIG OLE muzzle brake would probably be a lot more practical. lol ....and the term 'practical' is being used very loosely here.
Another huge round based off the 50 BMG case is the 14.5mm JDJ. Shoots a 1173gr bullet out of a blown out .50 case.
Another experimental round was the 50 FatMac. 20mm case cut down radically and necked for 50 BMG rounds.
I can't even imagine how fat a barrel would be for a chamber that large.... do you crane it to the bench or is it a two man carry.
So delivery by helicopter
that Fatmac takes Short Magnum to a whole new level. How many round before your barrel throat is gone! 2-3? lol
