Congratulations and welcome to reloading.
When I introduce a someone to reloading, I now recommend Trail Boss Powder.
The reason for this is that while learning the mechanics of bullet seating, primer seating, crimping, sizing and general handling a voluminous powder is a great convenience. TB is such a powder. You are not going to get tremendous pressures or ultra-high velocities out of it, but it fills the case to the point where if you have a short charge, no charge or double charge you will notice it.
TB was developed just a few years ago for Cowboy Action Shooting and is very forgiving. An asset to the novice. (But NEVER, EVER compress a charge of Trail Boss.)
After you have gone through a bottle of TB and are confident you mastered the mechanics of loading, then move to powders more tailored to your specific desires. Even so, TB is good for plinking, albeit a little more expensive than Unique or Bullseye.
For magnum performance, 2400 is nice. For casual plinking, Bullseye or Unique are my choices. But there are many, many other excellent choices.
Every manual (developed with different hardware in different ballistics labs with different lots of powder) has different load recommendations. All ammo manufacturers (that I know of) adhere to the (voluntary) standards of S.A.M.M.I. (Sporting Arms and Ammunition Manufacturers' Institute), but even so, their load recommendations vary, sometimes greatly.
Rule of thumb for Trail Boss if your manual(s) don't recommend a load:
1) Make a mark inside the case where the base of the bullet will be when seated.
2) Fill the case
to the mark with Trail Boss powder.
3) Pour the powder into a scale
4) Weigh the powder
5) Take 70% of that weight as your recommended charge.
To make the math simpler, you could repeat steps 2 and 3 seven times, weigh the accumulated powder and divide by 10. You also get an average instead of just one weighing.
Good luck.
