Charlie,
Your welcome.
The Encore is what you will want for the higher pressure cartridges like the 25-06. Depending on the ranges for deer the 250 sav, 250 Sav. AI, 257 Rob, 257 AI, 25 Souper (25-08), and the 25-284 are also options, especially if you reload.
If shots are going to be under 250 yards you wouldn't need to go to an 06 capacity cartridge, but it would sure shoot flat and hit hard.
A 15 inch Encore 25-06 barrel will have the performance of what you would get with a 25 x 308 in a rifle. Another way of saying it is that you will shoot around 250-300 FPS slower in a handgun barrel over a rifle length barrel in the 25-06
