Distraction is your biggest enemy. Focus in what you are doing. But start with....
1. Equipment. Start with a decent set-up. A reliable single stage press for low volume output is suggested. Brands mentioned above should be a good starting point.
2. Supplies. Casing, bullet, primer, powder, powder dispenser, dies and cleaning equipment.
3. Reloading books. Forums are plenty, you just need to find them. Books are reliable and tested. But forums will have some tweaks to your liking.
4. For your safety, start with the lowest suggested load. Then move up or slightly down to your liking. If you are not sure of what you are doing,
ask, ask and ask. Read and follow suggested load. These are available from most powder manufacturers sites.
5. Load a few varying powder weights. Do not make a bigger batch as you might need to make adjustments to your liking.
6. As mentioned above, find an experienced reloader who can be your mentor. Watch him reload. Ask the do's and dont's.
7. When using your reloaded ammo the first time, fire one round at a time. Do not rush. Observe the target, velocity if you have a chrono and recoil. Then tweak your load. Do not over or under adjust the powder load. For rifle loads, few grains over or under might be a safety issue.
8. Again, FOCUS. Safety is in your hands. If you are not sure, read the books. Ask experienced reloaders. If you are hesitant, do not proceed.
STAY SAFE AND GOODLUCK!
