I just bought one last oct and love it. I based my decision totally off the ballistic charts I read like the one listed below here. according to those it even slightly outclassed the 300s--now of course thats talking factory ammo
for instance the 160 gr accubonds for the 7mm wsm had better velocity than the 180 accubonds by the 300 and 300 short and more energy at 300+ yds (slightly less untill 300). In my humble estimation it beat all comparable calibers in overall ballistics including the regular 7mm and 300 except for the STW
I think the short mags are here to stay and I like the idea behind them
just my opinion
