Re: 25-06 Rem & Retumbo
I have to agree about Retumbo being a tad slow.
You might give RL-19, Imr-4831, or Ramshot Hunter, or Magnum a try. I have used both the RL-19 and Imr-4831 and got top velocity and accuracy with the 100gr BT's and Barnes-X.
I used Imr-4350 and CCI primers with the Sierra 100's as per their recommendation, and got great accuracy as well as top velocity with that combo.
All above load combos were at or above 3250 fps. and shot under 3/4" at 200 yds.
I just got some of the Ramshot powders a month or so back and am hoping to get out and give some a try soon. From what I have heard it is wonderful.
good luck on your loads
