"I think we are deviating from the purpose of the thread. Yes, all high velocity cartridges are inefficient, which is why I typically avoid them for large game hunting. Furthermore the energy makes little difference (other factors tend to be more important, such as cavitation/expansion volume in the wound) when it comes to effectiveness on game. Also the .25-06Rem. has a comparably poor trajectory/wind drift (for a med. range varminting?) due to the low BC projectiles available, so it just doesn't fill much of a role IMO. That said, it'll work if you really like it, and my intention was not to start a debate on the merits of most any cartridge (just throw out the idea that other choices are a viable option that should be explored for someone looking the re-bbl), so I'm going to leave this one alone and get back to the heart of the matter...the OP getting an outstanding deal on a very good Mauser action no matter what he decides to do with it."
I am not a judge of peoples things. I feel I shoot what I like and what I think is comfortable, I will not say your guns are not good enough, therefor I think I should deserve the same respect from you. if you do not like the caliber that I shoot, fine that is your right, but it is not your right to tell me I should choose something else.
Furthermore, did you even ask what I was hunting? no, you just got up there and started telling about its faults, All i hunt is varmints, and shoot targets.
I believe we each should be entitled to use the caliber of our choice, and others should respect that decision, and keep their opinions to their selves.\
I thank each of you for your input, I believe I have found a good gun, I love shooting it. I think that is all that matters, if we are happy with what we have, we are happier than those who always complain.
