Thanks for all the terrific replies.
For those who asked about the 270:
-scope is a Leupold Vari X3 - maybe 20 years old, with a plane jane reticle (no windage or elevation marks)
- I did put in a Timney trigger about 10 years ago. Waaaay nicer. No other work done to the rifle.
- rifle has that almost skeletonized synthetic stock and weighs 8lbs 4 oz with scope and sling. A tad heavier might be a good thing.
In terms of budget, I'd been thinking in the neighborhood of $1500 for gun, $1000 for scope
The advice to get a 223 and shoot it till the barrel sags is interesting. Hadn't considered that as a means of improving proficiency at longer ranges, but makes sense.
For those of you who quite reasonably recommend I stick with the 270, well, what's up with that?
If I wanted good advice I could have just asked my wife...
