5 Retumbo
Posted by Chris on Oct 29th 2024
I purchased Retumbo because it is a single base powder. Because of past usage of single base powders under varying weather conditions. Not being able to purchase primers I want for a specific powder, like double base and sphere powder specifically I like using a hotter primer and most people should. Another consideration is barrel length. The Retumbo will be used in a 7mm rm 24" inch barrel with a 162 gr projectile.

This is an excellent powder for 300PRC. It produced excellent accuracy and low Es and SD and excellent velocity. I was able to get 3020fps with 230 A-tips.
