If your budget can afford it???
One thought that I just considered.. If you have the cash you may want to consider buying a used scoped 22 rifle. Being new to shooting there are a lot of little things that you are going to have to master. None are tough but they each need to become second nature. I think I stink at golf, others that are kind just point out that I should take my clubs out of the basement more than once every 10 years. Shooting is like that, you need to get trigger time and burn some powder. Your caliber is a great one, lots of top performance and it will work for anything on this continent. Now the bad side, 270WSM ammo is expensive. I reload my rifle ammo but I am guessing that you are going to be looking at $30.00 a box(20 rounds). Compare that to say $2.00 a box(50 rounds) for 22LR and the savings will add up very fast. Shooting a 22 will teach you I think 95% of what you need to learn. If you can shoot the center out of a target at 50 yards with a 22, doing the same with a 270WSM at 100 yards will not be a big reach. Same mechanics, just more noise and some recoil saying hello at each shot.
