Re: New to reloading
The best thing I was told to do when I started was to get a reloading manual and read it, then read it again! That's exactly what I did and I had a good mentor that has reloaded for many years as did his father when we were kids. A good mentor can go along ways, but a reading a reloading manual and doing research online from trusted sources does to. I use Hogdon, Accurate, and other websites for load data as far as powder charges go, as well as other manufactures websites. I trust several of the guys here as well, because their intel has been consistent with what manuals and reloading manufacturers have said too. You have good equipment already, so that's covered, now you just need the knowledge.
It's a lot of fun, but can be a lot of work too with out good equipment....and even with sometimes. Start low and work high on your powder charges to see what your rifle likes. A chrony is a plus, but not entirely necessary if you want to trial and error it. Muzzle velocity intel is worth its weight in gold when it comes to long range shooting, so I would look at investing in it when you get a chance to. It will also tell you if that extra .5gr of powder is worth it or not.
Read up on how to "read" you brass, or "brass flow" and it can give you a wealth of intel as well. Also learn how to properly inspect your brass and primers after shooting to know when to discard your brass and/or if your load is to hot. Your brass will tell you a lot, if you know what to look for.
Good luck sir and enjoy. I find it a relaxing way to spend some time.
