Yes, but with a little work it will be a little better. Maybe a lot better.
About 45 years ago I bought a Remington 788 in a 308 Winchester. I bought it from a Western Auto store in town. I had no one to help with my selection and was starting from scratch. As time goes on I couldn't hit a barn unless I was inside and figured that's the way it was. I just couldn't shoot. Later I missed a very nice Michigan Buck as a guest on a dairy farm in Stanton Michigan. The host was not happy with me and he took the gun and he couldn't hit anything either. As time went on I bought a 243 Winchester in a Ruger 77. Suddenly I was hitting my targets. I bought the book above and went through the Remington step by step. When done it would shoot as good as a gun can get. I learned a lot about guns and go through all my rifles before I even shoot them. Trigger jobs, floating, bedding, lapping, polishing to name a few skills learned.
