RE: Oops!!
Every person has there own system or "Cadence" for reloading. If I could I would like to suggest a good safety precaution. I never put a case into the loading block unless it has a primer in it. And when I put powder in the case I always put the case in every other slot(the old timers will know why I do that). I always put powder into all the cases in the block first, before I seat any bullet's. Before I seat any bulets I take my flashlight and check all the cases for powder. It is very easy to see if you have powder in the case, and by checking the level you can make sure your powder charges are consistent. I also put the seated round back into the block for one final visual inspection.
Do not get in a hurry. If you are rushing yourself then you are screwing up to start with. If you have to rush your reloading then buy factory ammo. You are too busy to reload.
Yes I realize I am very anal about these things. But all my ammo shoots well, and I really really really do enjoy doing it. There really is something to a job well done. Tom.
