Like I said in the OP I want to stay with the more common choices due to availibility and cost, though the other suggested calibers will no doubt be good choices. I have whittled it down to those listed in the OP. I am leaning .243 or 7mm-08 though the 25-06 is also up there though. I do not reload, yet, this is on my list of things to get into. Finding .250 Savage, .260 Rem, and .257 Roberts around here is a bit more challenging for factory ammunition choices. On that matter the .243 seems to have the best factory options.

Thanks
