Re: 260 Remington ?
Hey Fish,
I shoot a 260 in comp's, as well as other shooters do, and it works great. After lots of testing, H4350 is my powder. Others have also had good results with H4831. Pick a 210M or CCI 200, and load up some test loads, and you will find the money load for sure. Have your gunsmith cut the chamber to shoot the 139's at mag length, so you can grow with the troat erosion.
