Advantages/disadvantages of faster powders in .270 Win?

[Triggernosis]

For years, I have been using 58.3 gr of H4831 to push a 130 gr SST bullet in my .270 Win deer rifle. I don't even remember the specifics of how i arrived at that load since it's been forever ago.
I'm getting low on 4831, but have a ton of H4350 in my stores. Is there any disadvantage to switching over to the 4350? From my reloading manuals I do see that I could use about 5 grains less powder than the 4831 load to keep the same velocity - that should result in less recoil, which is certainly an advantage.
Is there anything else I should keep in mind, as long as hunting-accuracy is maintained?

In the 6.5x284 some shooters use 4831, some 4350. Just work up a load and you will be fine.

Significant unused case capacity, as can occur when moving to faster burn rate powder, is not typically a contributor to enhanced precision.

You might very well be fine with the shift to 4350. As has been suggested, try published loads and see how it goes.

I have a load with 4320 and Nosler 150 BTs in a bone stock pushfeed mdl 70 that is a nice tight (overlapping) cloverleaf at 200. With that in mind I do prefer fuller cases V-165 or RL 22.

Aha! I figured there was something I was overlooking.

When I had a 270, I got the same accuracy with IMR 4350 as I did with H4831. The difference in recoil was indiscernible.
If I was considering it now, I would lean towards H4350, it’s supposedly one of the least temperature sensitive powders.
