The short mags are here to stay. We are just seeing the start of it. The newer WSSM cartridges line will expand as well. Every company is getting into the ammo and component game. The cartridges have everything going for them. Shorter handier actions and much more efficient use of the powder. Also now with better bullets that perform like bullets a couple weights heavier we wont miss the small loss of velocity with the heavier bullets. Barnes bullets are a good example. In 30 caliber even the 130 and 140 X bullets will penitrate and kill like 150 and 165 grain bullets.
