Absarokee is one of Montana's better kept secrets... paradise off the beaten path... I have thought about relocating there quite often. Climbed Granite Peak a few times, love the Beartooths!
The Howa is a great rifle and very good chance it will be a good shooter. You might want to check whether or not the barrel is free floated.
The 25-06 will be good for everything but a little light for elk. You can definitely take a bull elk with it but you can't guarantee 100% it will not run off a good distance after being shot. If your mobility is limited you should plan for that contingency by having someone who will assist you in recovery if necessary.
Light loads in the 25-06 are pleasant to shoot but max loads will kick a little.
My advise would be to sell the scope and get something better. It might work well and it might not. Optics is something you don't want to skimp on. if you have a great shooting rifle topped with an unreliable optic is a curse, and the best optic topped on a 3 MOA rifle is also a curse. I've experienced both. Sell the scope and get the best optic your budget allows.
Best of success, and you'll improve the odds with good equipment and good planning and preparedness.
