I've been thinking about a nice easy carry short rifle. Something with a handly little 18 inch barrel or the like, or maybe one of those 16 inch barrels ruger makes. I can't afford one at this moment, but i'm amusing myself by dreaming of next year's purcahses already 
Now i know how most 'standard' cartridges perform in normal barrel lengths - but which ones suffer the most or least in a shorter barrel?
We all know that shortening the barrel means a little less velocity. So my question was - which cartridges give up the least performance in shorter barrels, but still have some good reach to them? It'd be nice to have something like a 7-08, or 308, or 30-06 or 300 wsm (or something in those classes) but which one will do best in a shorter barrel?
As a secondary question - is it better to go with a lighter bullet or heavier to get the best performance?
Anyone got any experince/theories/ideas?
