I shot a mule deer buck at 340yds with the 140 Accubond starting out at 3340fps and there is no doubt that I would shoot any animal in the lower 48 with it after seeing the terminal performance and recovering the bullet out of the dirt.
At the speed I'm running them I'm keeping them to around 800yrds, I'm a little unsure if the Accubond will open up enough to deliver that energy so I am working with the 140 Berger also. It shoots 2.5 inches higher at 100yrd zero than my Accubond load so it works perfect.
The bullet speed and construction will determine you max range, I've shoot quit a few deer out at 350-400 yrds with a cal that only has 600-800 of energy and it did a wonderful job but the bullets were delivering 100% of that energy in the vitals, if I had shot a bonded bullet they would have not delivered hardly any energy and just poked through.
Decided on a particulat rifle yet?
