as far as how i view the .223 vs the 7.62 x 39 , sectional density kills more than speed if that makes sense.
But... A 69 grain .223 had a higher sectional density than a 125 grain .310... A 75 grain has a significantly higher SD. A 75 grain .223 also had more energy at 100 yards, and 25% more energy at 200 yards than a standard 125 grain x39.

Factory load ballistics compared shows otherwise.
I still don't buy it but not here to debate with you guys, I think we are all past

...for all the loads on Hodgdon...
Comparing factory loads the 7.62x39 has more energy than the .223. Handloaded also.
My Ruger No.1 7.62x39 123gr SST handload retains just under a 1/2 ton of energy at 300 yards.

Right, the fastest .223 Hodgdon handload has more downrange energy than the 7.62x39 factory load. But if we compare handloads, it's a different story.
The 7.62x39 Ruger No.1-A is a very fine rifle. Very strong action. Short and lightweight. A real joy to handle. Plus it's rare and not getting any cheaper...

only a handful made, not long ago, by Ruger. They were using up the last of the barrels made for the run of 303 British rifles from several years ago. Some say only 27 were made into 7.62x36.
Ohhhhhh wait then... I've heard the .303 barrels had dimensional issues? Are these actually .310 bores then?
these are .3105"
