Hey 5150 (your not !),
You will get some great advice on the forum here from the OG's that have hand loaded for a day or two. It sounds like you are off to a great start.
I also load 38/357 from my Henry. As time goes on you will slowly start upgrading dies and equipment as you see fit. Things like carbide dies help with not having to lube all the time, however, even though I have carbide dies, I still use Hornady/s lube spray when resizing.
1) I de-prime all my cases first (I am not resizing at this point , only de-priming).
2) I then always clean my cases, no matter the caliber (pistol, revolver, rifle). I have used a sonic cleaner for years, and have just received a wet tumbler for Xmas that I am going to start using.
3) Lay out the brass, spray with a light spray of lube, then resize, prime, drop powder, seat the bullet and crimp.
So my go to for plinking, paper, steel for the .357 is the Missouri Bullet 180 grain striker that uses the Hi-Tek extreme coating. The Hi-Tek coating really helps reduce leading in the barrel.
I also am a big fan of 2400, especially in the Henry. I have experimented with different load, and my best results and go to load for the Henry is 10.8 grains of 2400. It chronos at 1428 FPS with a 20 FPS maximum spread. (See below picture), at 50 yards with iron sights.

Let us know how the berry/s works for you. A lot of folks here use berries as well as Missouri bullets, in fact I was steered to Missouri Bullets by Rifle Tom, Vaquero and some others. It was great advice and I have been shooting them in all calibers, including my 45/70 Henry for the past couple of years with great results.
By the way, I shoot a lot of Hornady FTX bullets in my 9mm, .223 and for my Python. Great rounds.
