Have mentioned this before here, but I grew weary of searching for H4350 and after trying IMR4451 decided to switch over to it for the same purposes. This has worked very well on more than half a dozen cartridges so far, and 4451 has also worked well in several other rounds where I've never tried H4350. One example--it immediately became the front-runner during load development in my new 6XC.
What bullet are you testing John? I've wore out a couple of XC barrels and have some good loads I could pass on...
