Hi Ash, haven't tried any of the big stuff sadly. Worked up a load in 2208 that chronied out at 2700 fps but settled on the same 200 pp Woodleighs with 42 grns of some 2206 (not 2206H) i still have at 2400 fps. This has been a great load with excellent performance and penetration, but your idea of the .358 has some merit also

Good luck with what you decide, it is all part of the fun
