For what its worth, Bolt guns are known for accuracy, and lever guns for utility. Had you said that your friend tallked you out of one caliber for another caliber or one brand for another brand, that wouldn't have raised any flags, but one action type for another action type begs the question, "What are your goals for this rifle?"
Anyway, I have had (or currently have) a savage bolt actions in 308 and 300 win mag in left hand. The savages were very accurate and easy to accessorize (although long action left hand aftermarket stocks are hard to come by for savages, but still easier than other brands). If your looking for a factory accurate long(er) range gun, I'd look at the savage 10FP's in 308 or other packages in 30-06 (I got a lefty in that too). 300win mag is a good gun - a great one for hunting, but unless you are used to recoil, don't torture yourself.
A friend talked me out of a blr
Also have a BLR in .257Bob. its a toss up between it and the savage 99 I had in 308 as my most accurate utility rifle (out to 250-300 yards),
p.s. Real friends talk you into more rifles.
