All super helpful replies.
Thank you guys.
The only reason I didn't include the 270, 7mm-08, 30-06 is more pricing/availability. I'd be fine with the standard tikka, but...SW has been pricing their T3x left hand superlites less than the T3x SS. So it has been cheaper to (consider) pick up a superlite LH 308 or 6.5CM than any of the regular stainless models, and only those two calibers are made in superlite. With their current special, it's an even more aggressive price delta.

Is the 30-06 too much recoil for you? If it is the 308 is going to be the same thing.
If I were to start over again I would go with the 6.5, as it stands I started out with and have had no problems with the 30-06. It really is going to boil down to personal preference as both will kill deer and elk.
To be honest, I'm not sure. I'm a decent sized guy, but very limited time behind a rifle, and no instruction or mentorship. This 30-06 is the only rifle I've really used. I was successful with it this year, but I definitely noticed myself starting to flinch after several rounds at the range. No problem on the shot that counted.
As to the other folks questions - Current rifle is tikka, 30-06 stock pad. Lightweight scope. Seems to kick, but little to compare to. I'd like to get be a confident shot with a versatile 1rifle quiver, which requires more range time and comfort with chosen caliber.
It seems like a limb-saver pad is generally a recommended add-on, that will be on the list.
I've looked into brakes, I don't think that is the direction I'm going to head

Maybe pick up a cheap .22 for yourself for Christmas?? With good technique, ear pro, and practice none of the standard cartridges should lead you to a flinch.
Spot on! I feel that I skipped a few steps jumping straight in. I'm also backing up and plan on the .22 approach for sure! Thanks for the advice.
