Just a head up, it's much more involved than just reloading a few rounds. You half to shoot groups and groups to test the best powder load, the best bullets over all length ect.... to determin the most accurate load.
If you just hunt with the rifle and shoot the rifle at game... It's not worth the cost and time of reloading.
I feel I must take exception to your statement. When I was 16, I bought my first rifle. An old 303Br. Bullets were almost $10 a box, or in my world, 5 pair of rabbits. I did not shoot it much, but it did get me a deer that year (prior to that my deer were taken with a single shot 410 or 20 ga shotgun). When I was 17, I saw a "reloading" kit at a flea market for $8. I was intrigued. Talked to the guy for a bit and got it for $6. I still have that Lee Loader. Had to wait for almost a month before I had gotten bullets, powder, primers. Now, with a Lee Loader and no experience, choices are narrow for powder/bullet combinations, ESP when only one place had reloading supplies. I loaded and shot those for years. No refining the load, no testing for length, nothing. Just load, shoot more often, score better on deer. While I had problems with it, they were worked out and I used that method for years, eventually getting more equipment, components, and weapons until, today, I reload everything i use for game, including both of my first shotguns. I do not reload for 12ga field/skeet/trap since they are too cheap. I do, however, load my own buckshot.
even today, I don't target shoot however, I load all my own stuff and shoot far more than another "hunter" would. I'll find a load I want for my rifle, make a hundred, shoot them all before the season starts so that I know where that rifle is putting bullets, make another hundred for hunting and next year for practice. I could probably get 3 years out of the 200 rounds, but I make sure that I have a hundred a year. Do most hunters? Nope. My father would never shoot more than 3 rounds a year. Two to check the sights, one to shoot the deer (granted, the shots are less than 50yds, over a bait pile, but still, a box of factories last him 6 or 7 years.
Don't get crazy. There are more than one reason for reloading. Some do it simply to be self reliant.
