New reloader questions (powder and brass prep)

[SkiB4]

Hey guys, so I’m relatively new to reloading and have a couple questions.

1: 6.5 Creedmoor powder. Everyone is dealing with the powder/primer crisis, but I’ve been able to get my hands on 8lbs of H4350 which I plan on using in my 6mm Creed, but also have 8lbs of H380, 2 lbs of IMR 4350, and 8 lbs of IMR 4831 that I bought prior to really knowing what I was looking for. Ideally I would run H4350 in everything, and will if it is the only option, but would like to use H380 or either of the IMRs if possible. Anyone have good luck by chance with any of those in 6.5 Creeds?

2: Brass prep. I have a sonic cleaner that is excellent and does wonders, but was getting some dull looking cases. Was in Walmart the other day and bought a can of Brillo Cameo Brass cleaner. This stuff made all my brass look brand new. However I haven’t found a single thing on it in any reloading forums, and I know just about everything has been tried for cleaning and stuff. Am I missing something, or am I going to destroy my brass??
Thanks for your time everyone.

Started working up load for my hunting gun last weekend.
H4350 42.5 ended up being my most accurate load so far haven’t used the chrono yet COAL 2.8225

never used one but my understanding is you won’t end up with the prettiest brass in the world using an ultrasonic. It’ll be clean but not pretty if that makes sense

Edit: forgot- 123gr eldm

Make sure your brass cleaner doesn’t have ammonia.

Imr 4350 will work, and imr 4831 should work. H380 is going to be slow.

edit I would use a heavier bulley for the 4831, something in the 140ish area
