Did you go one shot at each target working around as in OCW workup, or all four at the same charge weight, then move on to the next target/charge weight? Just curious...
Also, did I drink today and forget I did... I'm only seeing four shots, not five ?
And, I chose 7-08 instead of .260 when I screwed a new barrel onto my Savage, mainly because we already use .308...and I'm lazy so I won't have to change the shellplate
...actually, the ballistics are very similar.
While I don't currently hunt, I may start- and the 7-08 should carry more kinetic energy to the target with the larger bullet. Worth looking into for your application.
