The 30/40 Krag Jorgenson had a long thin bullet as did the 30-'03 these were dropped in prefrence to the secant ogive design used in the 30-'06 primarily because the long thin bullet was less stable in flight. So now it is the opposite? I have fired thousands of rounds of '06 and .308 as a member of a military rifle team in the early '60's The last match ammo that I saw was still using the 148 grain boat tail bullet which actually shortened the effective length of the bullet engaging the rifling.
At the same time I also pulled and scored targets during practice. even at the 1000 yard range tumbling was rare. I fired the Leech Cup in '64 with a 30 MPH cross wind two firing points away from Olympic Gold Medalist Gary L. Anderson. I was not ashamed of my score of 79 (100 possible) in those conditions. We both used the target two points down for our aiming point. The bullet was being blown about 36feet sideways between the rifle and the target.
You think so? I don't.
I like the performance of the 6.5x55 Swedish Mauser round, but how can we make it just a little slimmer and keep the speed up? I think the new .270 round this weapon is featured with is a good start.
What's needed IMHO, is considerably more penetratation than is accomplished by the 5.56 NATO combined with a relatively flat trajectory and all in a compact round. This will require a very high pressure round, and a strong, reliable, lightweight, compact weapon. NO easy task.
I know you were using sarcasm BTW. I surely didn't want you to think I was so dense as to want to keep things as they are.
I like the PPC design. It's short for fast cycling, making it an improvement over the 7.62 NATO along with the substantial weight savings. If only it was a little slimmer with that punch, allowing more rounds to be stacked into a magazine carried by a foot soldier. Not so much of a problem in the SAW application mentioned on your link.
A slimmer case with faster powder would take a titanium chamber to contain the pressure, but would take less barrel length to get it to full speed. Maybe I'm all wet, but I think super high pressure is the only way to get what we need.
