I have a Remington 760 Carbine in 30-06. For deer I load it back a little, shooting a 180 grain ballistic tip over 47.2 grains of IMR 4320. this produces 2470 fps and bang/flop results on whitetails. For moose I boosted the load to 48.5 grains and 2630 fps.
The age of Remington firearms is normally determined by a two letter code on the left side of the barrel, just ahead of the receiver. If you want, you can look up this code and post it here, and I'll give you the month and year of manufacture.
