Hey garyo,
I have a 760 left hand pump in .30-06
I agree with labgrade about a little bit of noise from the front end, however in WI last fall I shot 3 deer with 3 shots (total...)
I know the first shot was LESS than 20 yards... she was leaping in great big arcs, when her feet hit the ground on the third leap BOOM, she piled up in less than 30 yards... Later that same day a buck stepped out about 50 yards away, BOOM, He fell over right there. I must say the rifle works.
I handload and the same load I use for deer I tried at 200 yards, all 10 went in a 5X4" rectangle, in/near the bull... my first time at 200 yards and I was holding on the bull (I sight in 2 1/2" high at 100 yards.) A .308 should be similar in performance. I am pretty sure a repeat trip to the 200 yard range would result in better performance by the shooter!
I think a Browning or maybe Tikka Bolt action is where I am looking next, but .30-30 vs .308 I would go .308 ...
My 760 was purchased used, you should be able to find them at local gunshows. I have leupold 3.5-10 vari-x III 40mm scope (which I recommend!) in an iron sighter base (can see iron sights under scope... JIC)
I have two 4 round magazines... can't see needing a 10 round box, at the range I don't shoot that many between checking targets, and the extra weight would be too costly hunting.
Let us know what you choose and how you like it. (remember WE are giving our advice, but its YOUR $ and you have to live with the gun.) If you can try shooting BOTH before you buy.
Good luck
Gfrey
