We were just razzin ya man. Don't take it personal.
Military 30-06 (M2 Ball) is ballistically identical to military 308 (M80) The M1A is a little lighter on recoil than an M1 Garand, but not much. With a shoulder injury, I doubt that you would be able to appreciate the difference between the two in regard to recoil.
If you have the option, try shooting an F A L. Ergonomically they are a bit better than the M1A and with the adjustable gas system, recoil can be reduced significantly. Add a good muzzle brake and recoil becomes a non issue. In addition to these points, a good quality F A L can be had for a little over half the cost of an M1A and F A L mags are a lot less expensive.(4 to 5 F A L mags for the price of 1 M14 mag) If you go the F A L route, a DSA StG58A will generally provide the same level of accuracy as an out of the box standard M1A for about 2/3 the price.
ETA. I just noticed that you are in Alaska. I have no idea what the firearms market is like there nor the availability so, please take what I have stated with that in mind.
