270win

Reloder 15 seems a little fast for the 270Win. You'll have better velocities and likely accuracy using something slower, like Reloder 19 or H4831.
 
300mag,

RL15 is pretty fast burning for the 270 Win. I would recommend the classic powder H4831 or RL22 for best accuracy and speed.

good advice above .............. stick with the 4831 and you will be impressed .Good Luck
 
I thought that the burn rate's was to fast, just sittin with 4lbs in basement. I will keep it for the 375/ thank's.

You could always neck that old dirty 270 up to a 35 cal and you would have plenty of excuse to use that RL15!

Just messing with you a little. Seems like it is hard to go wrong with RL22 or 4831 in the 270.. It is almost carved into stone I think! Scotty
