Thread: why???

the part your missing Micky is the difference between case / chamber design . . . the 7.62x39 is a loose fit 1940s battle rifle job with stumpy little usually cheap bullets, the majority of rifles chambered in it are likewise loose in every department.
now if you build a 7.62x39 with close tolerances in good cases with great bullets with a dialup scope i am sure you could increase your range some . . but its a cheap as chips rifle so who would, thats not its appeal.

the Grendal owes more to the PPC design which is a benchrest cartridge of some fame which came from the Russian but with major modifications . . . it does matter.
and people will push the range out on any cartridge maybe more than they should . . .

im thinking how can you push a .30 caliber case neck into a .22 chamber .. . .


" neither round does anything we couldnt already do yet they seem to be all the rage,anyone care to explain why they are so good because Im begiggered if I can see it. "

there are major differences that will be an improvement for some applications for poeple wanting that extra performance . . . i take my hat off to them
