I inherited a rifle that has sat for at least 2 decades and want to clean it up and use. It is a Stevens, Savage Arms .30-30 model 325-B. Can you recommend a cartridge that would work well with this gun?
It is virtually impossible to predict which ammo will work well in a given gun. Every gun shows decided preferences for one or two loads while performing poorly with others.
The only way to find out is to purchase several boxes from different makers in various bullet weights and shoot them to find out what your gun likes. It is an expensive proposition but I know of no alternative.
Even two guns with the same make and model will show different likes and dislikes.
Buy a box of Winchester, a box of federal and a Box of Remington 150 gr SP's and take them to the range. To be perfectly fair, clean the barrel between each brand to remove all variables.
S.Bear is right on about the reloading end of this topic. My only trouble with rechargeing the 30-30 case is the brass is weak/thin on the shoulder, and will crimp down on bullet seating,at times. Also just a little too much case lube and you will leave dents in the shoulder. Good luck.
