Sorry about the botched, double post. My server crashed at the worst possible time, and posted my topic sans text.
What I wrote, that didn't show up in my post, was this; I just bought a Contender Carbine in 30-30, and was thinking of another barrel, for whitetail and mule deer, cougar, javelina. Max range about 300 yards. Would the 6.5 JDJ work, or would I need to move up to a .309 JDJ instead?
Thanks for any replies.
Mike
