I have just loaded my first box of ammo. I first used a dummy shell to find out what seating depth to use. The shell went into the chamber and the bolt closed easily. I then loaded a box at that same length and the bolt is hard to close. I was wanting to know what caused this to happen and is it alright to shoot the loads when the bolt is hard to close. I believe that the bullet is seated deep enough since the dummy shell goes in with ease. I am loading for a savage 22-250 using rem. brass and 55 gr. v-max's.
