I need help with the quick load and gunpowder, which I will use the Barnes TSX 300 gr. My .416 rem mag with 24" barrel. B. C. .298.
I use Norma powder 203 B to the Swift A-Frame 350 gr. Should I have the same to the Barnes TSX or can I have Norma 202 or 204?
What is the maximum load that I can use?
I thank you in advance for your help!
