I have one in 7mm 08 that I love!! You should really consider that caliber. It has a great balance between power and recoil. The great BC of the 7mm bullet gives great long range capabilities. It actually carries more power than a 308 out past 350 yrds or so. For deer, it's heavier bullets give a larger margin for error than the 243, and allows for more shot angles you wouldn't want to take with the 243. The only downside is slightly more recoil.
Used it on this guy in 2010.
300yrd shot, quartering away.
Encore 7mm08 15inch factory barrel Simmons 2x6 eer scope.
45grns of H-380 under a 140grn speer soft point reload.
With a 200yrd zero it only drops 9 inches at 300.
2011
Same gun and load.
110yrds directly facing me. Took him through the white patch under his chin.
