Re: Get me started
Go to your local library and get the "ABC's of reloading" great book, or purchase and older one online. Also you can get a Hodgdons reloading manual (it is only $3 in magazine form.) Has descriptions of all IMR Hodgdon powders and loads for rifles.
Get a notebook and start writing everything down.
Start with your rifle, bbl length , twist rate.
And your ammo, FGMM, what is the drop at 300, at 600? What is the bc of the 168 SMK, what would be the result if you had a 175 SMK traveling at the same velocity? How about your FGMM at 10K feet elevation.
As you start to answer these questions, and learn about reloading, you can set a goal to match your current factory load.
Have fun, check twice, be safe.
