I recently shot my first Elk. The guide insisted I use a .30 cal instead of my 6.5 PRC. I obliged with my 30-06 Tikka. The big bull went 3 steps. Great day.
It started me thinking about cartridges. My 6.5 PRC is a Proof Elevation MTR 24" bbl. For me, It is the most accurate rifle I own. It loves the Berger 156 gr EOL that I purchased from Choice and achieves 3010 fps. It shoots UM loaded 147 ELD-m at 2975 fps. My Carbon Six 24" barreled 30-06 Tikka groups 165 gr Accubonds very well at 2940 fps and shoots Barnes 168 gr TTSX even faster at 3025 fps. My friend has a Tikka 24" 7mm Rem Mag that shoots factory 162 gr ELD-x at 2925 fps.
I realize I am comparing different bullets and factory ammo to semi-custom ammo but these are the cartridges I personally saw chronographed. After entering the info in a ballistics calculator, the 6.5 PRC, at 300 yards, has considerably more velocity then any of the others. It has more energy, less drop and less drift plus a higher sectional density. Because of the higher BC bullets the 6.5 PRC has an even bigger advantage at 400 and 500 yards.
Is the 6.5 PRC really the marginal cartridge for Elk simply because it is 6 gr less weight and .020 less diameter? Is the issue that most feel the 180 gr bullet in the 06 or the 7mm is a much better choice for bigger game?
