h4227 in .243 Win.

[rhill]

I have a couple of lbs. of H4227, can't find any reference to it for use in cast loads for the .243 Win. Lots of info on IMR4227. Can anyone point me out to a source of loads using H4227? Or is this powder not recommended for this use? Thanks!!

Use the same start and listed max loads as for the IMR4227and work up for accuracy. The 2 powders are close enough together in burning rate and performance that, with cast bullet loads, there won't be much difference.

Thanx Larry, I thought that might be the case but I wasn't sure.
