Man… Thank you so much for the input guys. I am now completely lost and not sure which way to go ha ha. There are so many options. I currently have a Ruger M77 Mark 2 .270 that I plan on using for elk and maybe bear. I am really trying to find something I can use for Deer hunting with an ethical range of up to 500 yds. I also want to use it for long range target shooting. Coyote and other predator hunting at what I would assume will be long distance shooting as well. But I also want to have it really suppressor friendly (short enough barrel I can easily navigate and hike the mtn/forest terrain) with it and not have it getting caught on everything 
But also be really lite to help with easing fatiuge from carrying it all over the MTNS lol. I plan on putting an Athlon HELOS BTR Gen 2 4-20x50 on it as well.
6.5 PRC in 20" barrel(or 22" for that extra ft/sc), like Jim said. You won’t be sorry.
So I have been looking heavy into the 6.5 CM, the 6 CM and the 7mm-08. It looks like the 6 CM would be a better fit for me than the 6.5 CM. But Tikka does not make the 6 CM in any flavor or T3X So I am down to either choosing the 7mm-08, the 6.5 CM or the 6.5 PRC. The thing that makes me nervous about the 6.5 PRC in a shorter barrel is I have heard and read that the barrel life is not that great. Not just in a shorter barrel, but just the 6.5 PRC in general. I want this to be a really good investment that is going to last a really really long time. Which makes me lean towards maybe the 7mm-08. But still trying to decide on a barrel length that works well with a suppressor AND allows to still do a lot of long range shooting. Both for target shooting, coyotes, wolves?
Oh man! @mwoolsey I got all excited about the 22 CM! I thought that was the caliber I am going to do. But then reality hit me And I saw how expensive it is just to get a rifle in that caliber
Not one to discourage a new rifle but the 270 is probably better for mule deer than elk. Shoot 130’s in it and you are 6.5 like anyways. Then go to a 7 or 300 magnum to cover the bigger stuff. Well getting a new bigger rifle is getting a new rifle. 
Ha ha ha. Thank you. I appreciate the advice. And I completely understand that my Ruger 270 Winchester is on the lower end for shooting elk but I have harvested three or four elk with it and I’m happy with it. I’m really looking for something that’s more of a Swiss army knife for long distance shooting, deer hunting, predator hunting all of that. Has anyone ever tried to make a 22 creedmoor out of a Tikka t3x light? 22-250 having the barrel rechambered?
This is a great discussion. I have modified a number of my rifles by chopping down the barrel and having them threaded. The shorter the barrel, the better in my opinion. It makes a big experiential difference when you go from 24 to 20 or 22 to 18. But you want to check what kind of muzzle velocity you get when you drop down.
From experience, I can say that a shorty 6.5 creed is not worth it (that is, if you want to do more long range stuff). I have a 20" tikka threaded in 6.5 CM, and it’s fine in the woods, but out west I think it would be a bit limited. Handicapping an already anemic cartridge is not ideal. You just lose so much velocity; it would be better if I had done the same length but used 6.5 PRC instead of CM. Or maybe the new 7mm BC is an even better option.
That having been said, if you do the math on your particular load, it may not be an issue depending on the goals you have. For example, if you can still squeeze 2650-2700 fps or so out of your 6.5mm gun, that might be adequate for your needs.
I would personally hold my limit at 400 yards on live game, and really I’d like to see it 300 and in. If I can afford to get closer, I will. My reasons are just mathematical–even if I am shooting 1 MOA at the range under good conditions/benchrest, etc., then in the field I assume I will be closer to 2 or even 2.5 MOA (since conditions are rarely if ever that ideal). So this cautious approach naturally limits my range anyway. This also generally means I can afford to lose some muzzle velocity with a shorter barrel. If I were stretching to 500, I would want more velocity starting out for sure. (Either by lengthening the barrel or switching to a stronger cartridge).
