Speaking of powder, I seldom try many new powder's. Still a lot of 50 year old types that do well for me. So many new one's you could go broke just trying them. have a load of H4831 in my 6.5x06 that averages under 1/2" on a regular basis. Why should I change that? There are so many different powder's out there today I have no idea how anyone can keep them straight. newest powder 's I use are varget and RL-19 and RL-22. Not a clue how old they are. Wish I could still get N-205!
