Yes that too.
Not a really affordable rifle, not really practical for plinking at the range and getting skills up if you don't have them. Wicked expensive ammo. Not real practical for shooting at short ranges either, but the OP didn't ask those questions.
A super accurate match grade .22 bolt action is an awesome place to start, followed by a great bolt action in .223 because of the volume if shooting you can do for price, while focusing on mechanics, wind, light, mirage effects, etc. then when you have learned a lot on those platforms you can pick the next caliber for the kind of shooting you really want to focus on. It may be a 6.5 based cartridge for bench or 1000 yd competition, or a super sniper round and platform. But often tightening up the nut behind the butt stock is the best investment.
