I have some limited experience with blending powders. There's a reason why they tell you not to do it.
Early in my reloading career, a little bit of IMR4831 got dumped in a can of IMR4895. Instead of 'waste' it, we decided to use it on my friend's brother's .270. We loaded some 130 gr bullets using the minimum charge of 4895, intending to work up from there.
The first shot welded the bolt closed. This was in a 760 Remington, not the strongest of actions but not the weakest, either, and certainly capable of handling factory ammo pressure.
