I have a 6mm-284 that has quite a bit more case cap. than a 243 and it is still way too slow of a burn rate.
RL22 is about as slow of a burn rate that is realistic, my favorite in the 243 with 95-105gr bullets is IMR4831.
Right now on this forum many are gacking allover themselves that RL17 will do anything...it is a much better choice than Retumbo.
VVN160,RL19,H4831, hell even JB's TAC that he claim's you will never need to clean for the life of the barrel is a better choice than Retumbo......you've been gettin bad advice


Retumbo is the powder of choice for the 243 Win in my little world. But then I would hardly be inclined to push the silly lil 243 Win as much of a gun. laugh laugh



Buy an MTM drop tube if you want that 243 Win to run with 105s. wink
