Trying to work up a load for 107gn bullets in a 6BR using 8208 XBR. Anyone use gold or blue Federals or CCI 450's with 8208 XBR in their 6BR? Trying to conserve my CCI 400's and Varget. I am thinking the 450's may get me better ignition. I had some nice groups, in the mid .4's doing five shot groups at 100. However the ES/SD numbers left a lot to be desired. Velocity was on the slow side but the rifle was built off a salvaged Stevens 200 action that had a fight with a forklift. Temps are in mid 50's but in a couple of months will be in the mid to upper 90's so I won't be running any stiffer loads in it till the weather gets hot.
