Yes. Tht's what post number 4 recommended. By the way, at short range, there is no "Group score"
Going to a match, which you indicated you'll do today, is the first part. If you like it -- hard to tell without shooting, I know -- the next step is to get involved in the sport with reasonable equipment at a reasonable price.
Be reasonable. If there are only score matches near you, shoot score. If only group matches, shoot group.
Read a couple of books. That is still the best way to get thoughtfully prepared, vetted information.
Price has several components, time and dollars. If you order a new rifle, it will take longer than if you buy a used rifle. It will also cost more. A used rifle should be presumed to need a new barrel, but it does happen that there are some used rifles with good barrels. The ones with good barrels cost more, but you don't have to wait for a smith to chamber up a new one.
Why are there good rifles for sale used? Because as you are about to find if you start down this path, people are never satisfied. They always want "something new" even though the odds are it won't be any better than what they already have. Getting the money for that "something new" means selling what you have.
We have all been beaten more than once by somebody shooting 15+ year old equipment, bags, dies, presses, etc. (except barrels) -- Like anytime you shoot against Jeff Summers, Mike or Patty Jennings, Mickey Connely, etc. etc. etc. They are shooters, not equipment nuts. Most of us just nuts. I'm going to a match in a few days, and the rifle I'll take is 15 years old. I have 3 newer ones, but right now, the older one (with a new barrel) shoots better. The newer ones came about because I though something was a neat idea. The ideas were neat (drop port, dual port w/ejector, etc. etc.), but the new rifles don't shoot any better, primarily because I don't shoot them any better. Benchrest is full of people like me in that regard.
If you can find somebody getting out of the sport, you can pick up an entire kit for a good price.
Basic stuff works fine. I still use a RCBS Partner press, as does, I believe, Jackie Schmidt. Much cheaper than a Harrell or Hood; takes up a little more room.
If there is any one thing I might look for with used equipment, it is a rifle that has performed well in the past. All actions are not equal, but if there is a problem with the action (usually in the ignition system), it can be very hard to find.
Good luck.
They do a great job.
