Hello. I do not plant to get into reloading but I have been watching a few videos on youtube about it. It really looks more like a hobby and so far, none of my firearms are too expensive to shoot. I can see how reloading is very useful if you have an older gun that requires more expensive rounds. When charging the case with powder, how do people know what amount to use? Is there a book or something? Say I want to reload a simple 7.62x54 rimmed; how much powder do I use? Powder is measured in grains? I know the bullet is also measured in grains. From what I have been viewing, people use a machine that you pull the lever down and the powder drops into the case. I think you do this multiple times to get the correct amount and then you go to town and drop powder in all your cases. I know overcharging is dangerous so you need to pay attention to how many times you pull that lever down. How many grains go into a standard 7.62x54 rimmed round? Again I appreciate all the help. I don't want to give you the misconception that I know nothing about firearms. I know quite a bit but reloading is not my thing and I have never tried it and at this point do not plan to. It looks fun though!
