gotta chime in with the 'reload' folks. building a custom gun and shooting bulk boxed ammo through it is like buying a precision-tuned race car and then trying to race it with pump gas. Just not gonna work.
All the same, I'd suggest a 243, 260 or maybe even a 7mm08 if you ever intend on using this on deer. All those cartridges are perfectly satisfactory on smaller game too, so long as you're not worried about pelt damage
