The issue here is whether one should load a powder using the data for another.....yes 4350 was stated but the issue is not IMR/H-4350...it's data substitution.....got it?
Really a simple matter. Not sure why your having trouble grasping it.
No, thats what you want to make an issue. You should start a new post of your own and not hijack this one if thats the issue you want to make. My issue, and my comment to mossy, not you, was yes with his particular caliber, and bullets, it is safe to start at min load with either 4350 and work up. Do you GET IT? The last poster was asking me, not you. I clearly posted, I don't know if 4831 can be. I have talked to Mossy on the phone about it, and clearly talked about 4350.
If you want to discuss substitution, you ought to make a new post.
