Re: Questions about my Mosin Nagant
... and back on topic.
I feel I was in your shoes back many moons when I was 18. Day after my b-day I walked into my local big-5, grabbed the first RC k98k off the wall and bought it for $89.99. 10 days later (damn CA) I picked up my rifle and a box of ammo, and headed to the range. Shot pretty well, for what I could do with little time behind the trigger. The rifle was soon packed away until 2008 when I got out of the Army over a decade later. Knowing what I do now, I am amazed I got what I did.
A 91/30 is going to set you back about $100 when all is said and done. By a box of cheap heavy ball whatever, and take it to the range. A few hours of shooting 4" groups and you will put the rifle up, or start fixing on it to get those groups down. After a stock, bedding, scope, smith work (if you don't DIY) you will have another $200 sunk into the rifle. You will still be shooting meh groups, because ammo selection is crap, and you have little time behind the trigger. Now you have a $300 bubba'd 91/30 that has little to no resale value, and a great dust collector in the back of your safe/storage cabinet/closet. Much like my K98, just sits in the back corner and is fired once every blue moon.
I may be way out of line here as a n00b, but my advice to ANY beginning shooter who wants to learn the ways of LR... pick up a decent bolt action .22lr (Savage MKII, Remington 5xx, Mossberg M44, hell I started with a Remington 41) I would personally avoid the semi-autos as they promote ammo expenditure over accuracy (even with me). Find yourself a used or new Bushnell 3200 10x40 Mildot, and mount that up. You will learn a whole lot more about LR shooting with a .22lr at 100-200yrds than you will ever learn with a 91/30 at the same range. The money you save in ammo costs can be saved to buy a decent center fire bolt rifle.
When you have $500 saved up, go to your local pawn store and dicker them down on a used Stevens 200 or Savage 10 short action (larger aftermarket), try for .308 as it's the most common, and has the most amount of data out there. I see these at the pawn for $300 all day long. Take that scope off your .22lr, and swap it over. Start at the 100yrd line and shoot until you can put 5rds under a quarter EVERY time you pick the rifle up. Them move out to 200yrds and do the same thing. Wash and repeat until you have reached the maximum accuracy of your rifle. By this time you will have learned the finer points of LR shooting, and possibly reloading some. You will know more of what you want in a rifle, and caliber, and make an informed decision on where to go next. IF you choose to buy a new rifle, go ahead... or you can just spin off the factory barrel from your Stevens/Savage, and spin on a new pipe, change out the stock, and have a totally new rifle for under $500.
So..
Buy an accurate .22lr bolt rifle, and some decent glass for it
Shoot that until you can stack the rounds on top of each other.
Buy an accurate modern bolt rifle, and swap over your glass
Shoot that until you can stack the rounds on top of each other.
Buy what ever you want based on what you have learned during the previous stages.
