1500-2K If your not doing long strings of fast fire.What kind of barrel life could I expect?
Im thinking this is a great idea.........hmmmm may have to do one sometime.Whether a straight 6.5x55 or an Ackley
FWIW At Connaught range in Ottawa the toughest F Class guy to beat at 300 meters shoots a long throat 223 with around 0.190" free bore. He usually uses bullets in the 85 to 90 grain range.Since you mention budget and only shooting to 300 yds. I would stay 6mm or 6.5. A 6br or 6x47L, also 6.5x47L.
I have already done barrel swaps on my M12 Savage LRPV. It went from a 204R to 223 R. It now wears a CBI barrel and is VERY accurate. A couple weeks ago I was playing with seating depths and at 100 yds put 3 Hornady 68 gn bullets into .110". A best for that rifle so far. I was amazed at how a couple thousands of movement can affect accuracy. I have all the tools to do it already, just not enough knowledge of different cartridges and how easy it is to tune a load for them.I can’t find it on my hard drive at the moment… but once upon a time someone went to the trouble of organizing a study of cartridges by bolt face and action length that was worthwhile. I’m sorry to bring it up without being able to show it.
On the other hand, since you are on a Savage action to being with, I would suggest learning how to swap bbls and try one or more of the variants based on the 308 case like all the derivative 6mm designs. There are so many to choose from that you would have to hold back based on what brass and such you can get hold of.
With the advent of Alpha and Peterson brass, you can do the wildcats with factory brass that until recently would have required fire forming. Even a straight 6 BR is a lot of fun and what I call The Easy Button in terms of brass and tuning.
With your rig, I would start with a fresh 308 bbl and then learn to swap bbls in the case where you haven’t tried this before. You may like the experience, or you may never do it again. Since you are single feeding and only running 300 yards, it isn’t about LR energy as much as it should be about your budget and having fun. YMMV
