I have just recently purchased a cz 527 in 223 rem. Have 55 gr.bullets

Does anyone use N-130 or N-133 or N-XXX?

I think I have access to this brand of powder.

Thank you.

Slim,
I have used N 133, 140 and 540 in my .223 Rem though mostly with heavier bullets 69-80gr. Vhitavouri is my overall favorite powder to for any rifle I reload for.
