should TRY a 6lb, 10" CAR-15 sometime.
Even with 10" and 1 ozs of reallly effective sound suppressor, it weighs no more, and is no larger. Its ammo weighs half of what .44 or 30-30 ammo weighs, so you can just as easilly carry the .22 conversion unit, and 20-30rds of 223, and 50rds of .22lr, as you can 30 rds of 30-30 or .44 ammo. How often is big game in season, hmm? 10 % of the year? Why bother with 30-30 or .44 on varmints or small game? You certainly aren't going to do well at any sort of match with such a rifle and load. You can't build the lever from a parts kit and an 80% finished lower receiver, like you can the AR? So why waste time and money on a demonstrably inferior gun and load, hmm? Hell, a $150 sks and 8c a shot ammo for same can at least match the ballistics of the 2 lever calibers, and double the ability to get multiple targets.
