Well thanks to Scotty i decided to burn some powder in my whelen saturday and Sunday. It's always a good day to do that,Temps on Saturday were low 70's and Sunday low to mid 80's.I wanted to try the hornady 200 grainers, i have a couple hundred sitting around.My powders to try are as follows. Always RL-15 , Imr-4064 and Imr 8208 XBR (i am really loving the XBR ).I went with 3.200 col..R-P cases and trying CCi-250 . RL-15 was first.. as always great groups. But i was not satisfied with speeds. 3-shot group averaged 2680 fps with 63 grains. Next was IMR-4064. I have always liked the powder but have not used it lately (my stock is still in the old metal cans).Shot good groups but it too was slower than i wanted. 3 shot group 2739 fps with 61.5 grains. Then today (Sunday) got to try IMR-8208 XBR. This stuff is fast becoming a favorite. It is my new go to powder for.223 Remington.I not only got good groups but impressive speeds out of my classic Remington. 59.5 grains averaged 2838 fps. 59.8 grains averaged 2871 fps. No pressure signs and i am going to work with seating depths.All in all a good weekend with my favorite rifle. Lee
