OP, do your homework. Lots of sites offer components and prices. Lots more offer factory ammo and prices. Research what a competent set up looks like, and price at the Big Box sporting goods stores. Find some reliable load data for powder charges - by having done all that, you will know how many 45 grain or 63 grain or 22 grain loads you can get from a pound of powder, and figure it out for yourself.
At 200 to 300 rounds a month, you should be able to save 50 to 100 bucks, depending on bargains you may get with factory, versus bargains you may get with components, and what quality of either you decide to use - premium hunting rounds, or premium component bullets, versus bulk factory ammo versus bulk cup and core bullets. Over twenty years and a few barrels, you will $$$ ahead. Or not, if you hang up the rifle in favor of beer or bs.
Do your own valuation, and then you, and only you can decide if learning a whole new aspect of shooting is worth it. Coming on a forum and asking the membership if something is "worth it" is just pointless.
