Even if you do find someone to teach you, make sure you read the instruction portion of a good reloading manual. Your teacher may very well forget to mention something or may have an unsafe habit or two.
I think Hornady's manual does a really good job of explaining the process, but a lot of people prefer Lyman's book. Either one is suitable.
BTW....most of my loads end up over max.
Freaks some people out
Differences in some manuals, old vs new.
Powder lot variance and chamber dims.....you always start in the safe zone and watch for pressure.
If you show hot before max, well.....youre done.
Book doesnt mean squat.
Same as if over max and no over pressure sign.
A LOT of people think the book sets all limits.
Speaking of unsafe habits...
The companies that publish these books use specialized equipment to measure pressure. They determine max loads because that load is the maximum that will stay under the safe pressure limit for a given cartridge.
Hookeye may be braver than I, but I don't risk blowing up a firearm inches from my face because I think my looking at a case is a better measure than a manufacturer's test barrel and equipment.
Everyone gets to make their own decisions; I have decided that the component manufacturers are to be believed when they set a maximum.
