who hear has been,,, in country..only those can answer....The sa80 as you put it,,,< which by the way is has not been called for years > is a good weapon,,,,
the only reason it cocked up first time is it was designed by engineers and then built by accountants,, know your history,,,the accountants messed it up,,
and bud you have to know,,getting shot by anything,,even a 22 moving at 2000 fps,, will put you down,,, i like 223 remington,, its a good flat round,,,
7.62 is great if you can get something to shoot it out off,,,not a bloody bendy wendy ak47,,, if theres even any left..as most are cashmere copys,,,
next 7.62 needs a certain length of barrel to get up to speed,,other wise its a slow heavy slug with less range than a 22,, so you can blow out using 7.62 for any thing other than contact at over 300meters,, if you can see that far ..in the heat,, 7.62 for big guns at range.. 22s for close up or under 300meters.
by the way i know its coming,,by 22 i mean 223.remington,, or if your in the mob,, 5.56MM.. 22 BEING 5.50MM...PLUS HEAD SIZE..
and i can carry more 223 than i can 7.62...and thats what its all about,,,as for malfunctions where do you get your info from,,, the M4 has been the worst gun in the dust.. and boy you have to know how much dust there is,,,
now also seeing as most contact is at short range...under 300 meters...why a bigger round,,,theres allready a squad 7.62 rifle,,, and sometimes a SAW or bigger in the form of a lmg in 7.62,
by the way,,history,, the father of the SA80 the EM models started as 4,60mm so that makes 223 a step up,,next they went to 7.62,,,but found it lacking with what you could carry ammo wise in to the field,
