[QUOTE="65WSM, post: 1116376, member: 9551"] Dear Mr Crocket: IMR 7977 is too slow for the .270 WSM. The only application might be the very heavy for caliber 160 gr bullets. You can fill the case with as much as you like and the velocity will still be below 3000 fps. Reloader 23 will work with the lighter bullets. It is a Bufors powder that Alliant is importing for our benifit. It will be temperature sensitive like other Bufors powders, RL-22 and RL-25. It may be smoky and produce a lot of carbon build up. Reloader 26 Swiss powder from NitroCheme and should produce top velocities with the heaviest bullets in the .270 WSM. Reloader 17, the only other NitroCheme powder available in the United States produces amazing velocities compared to other powders in its 4350 burn rate range. The 150gr bullets should respond well to it. I have tried 130 and 140 gr bullets in the 6.5 WSM with top velocities at 130 gr. VV N-570 is still the top velocity powder with 140 gr. My experience with the 270 WSM, is that MagPro, a very dense ball powder made at St Marks in Florida produced the highest velocities by a wide margin with the 140gr Berger that I prefer in that cartridge. I only have one pound of RL-26 so far, I bought it on sight at Cabelas and it was the last one they had. [/QUOTE]
