Just to add to what the good Doctor is telling you, early in my reloading learning curve, I did something similar, I was loading a Ruger 300 Win, mag and used a load that was about halfway in the books and substituted a different bullet of the same weight but different style and to make a long story short, I had to use a piece of wood to get the action open. Rifle survived, but the primer dropped out and the primer pocket was VERY enlarged and the brass case had flowed to the shape of the bolt face. Lesson learned the hard way. Work up each and every bullet from scratch when substituting components.
