MMAM, This is something I would never do, but since you did the deed, I assume you shoot a magnum, 300Win, correct. If you really do want to load this powder, try (with 180gr) 72grs. of it, I don't see why that would hurt anything. A buddy of my dad's once loaded some 160gr. partitions for his 7Rem. mag. and used 70grs. of IMR4831, well If you look that up, it's not even close to the 62.4gr max in my Hornady manual for a 162gr. bullet, (Me thinks he was drunk), At any rate, my dad shot these, not knowing that they were over max by almost 8grs. The rifle didn't blow up, just a big flame came out of the barrel, and I noticed the case showed some stretch, about .015" I'd say, this was before I started reloading, so I didn't know either he was shooting some 'HOT' loads, when I started to reload and found out that it was a hot load, I pulled the rest of them and loaded them to 62grs of the same powder, so that being said, if you use 4350 data, you shouldn't have any disasterous results, but you never know. BTW, IMR4350 gives a higher velocity than 4831 anyway, so mixing the two aren't going to do anything better. Oh, the powder that Hornady uses for their Light/Heavy magnums starts out as a jel-like substance that is actually poured into the case, and then dries, If you pulled a bullet from these loads, you'd have to pick the 'powder' out and you'd never get the powder back in the case once your finished, you want more velocity, get a bigger cartridge.
