I don't know if this has been posted yet, so here goes...
There have been several magnum variations in the last few years that have become popular for deer hunting. IMHO it is overkill to shoot at a white-tail deer with a .300 type ultra magnum, but to each his/her own...
My personal favorite is the .270 Win. Nice combo of velocity and accuracy. Especially nice because the factory loads come loaded fairly potently. (Which can't necessarily be said for the .306 due to the danger of firing hot catridges through older and weaker rifles)
BTW I live in KY so I never need the 500 yds that the super ultra dupe magnums claim.
