Hello! This is my first post on this forum
I have a little wondering in my mind witch I dont seem to solve...
20mm m50 series ammunition (or equal made ammuntion) fired from the giat m621 cannon gives a practical range of about 1500m and a maximum range of 5000m, according to this site: http://www.probertencyclopaedia.com/cgi-bin/res.pl?keyword=Giat+M621&offset=0 (This is assuming the weapons is fired on the ground on ground targets, and not in an anti-aircraft role)
What if it would be fired with PGU-28/B ammunition or equal? Perhaps the ranges would increase to 2000m practical range and a maximum of 6500m?
And what about velocities from other 20mm weapons in the same caliber (20x102mm) From what I understand, the velocities is about similar in m61 vulcan, m39 and giat m621 cannons.
So what does this have to do with rifles? I am experimenting theoretically with large calibers (in rifle dimensions) and long ranges, to go even further than .50 bmg. The 14.5x114 is in mind, but assuming that isnt available, and just theoretically experimenting with small 20mm rounds...
The main question simplified, what is the difference between PGU-28/B ammunition and m50 series? What ranges are we talking about?
Perhaps Tony Williams have an intresting answer on this question, or maybe you could give an approximation?
Maybe this is posted anyway in the wrong category, if so, may the moderator move it.
