Hodgdon doesn't list any loads for 110 gr bullets with powders slower than IMR-4320. Can you load that bullet with IMR-4831? Yes, but it won‘t provide optimal velocity and performance. 3031, 4895, 4064, Varget or 8208XBR would be better options for that light of a bullet. Save your 4831 for bullets weighing 165 gr and up. It should perform much better with heavier bullets in the 30-06.
I loaded some Sierra 110's in .308 Win cases with 50 grains of IMR4895 that clocked a bit over 3300 fps. But the barrel's 1:12 twist spun them way too fast and accuracy was nothing to write home about.
The normal unbalance across those bullets spinning 198,000 rpm caused them to jump off the bore axis due to centrifugal force. Spinning them at about 120,000 rpm is about right for velocities around 3000 fps.
The M1 carbine's 1:20 twist barrel shot 110's out at about 2000 fps spinning them at 72,000 rpm; good for that lower muzzle velocity. A 50% faster muzzle velocity for the 110-gr. round nose bullet doesn't need a faster twist; they'll spin 50% faster at 108,000 rpm which is good to keep them stabilized at the faster speed.
4831 powder won't shoot 110's from a .308 fast enough for their intended purposes, but maybe with better accuracy than 4895 will. I'd save it for bullets heavier than 220 grains in a .308. IMR4350 did well with 200-gr. bullets in a .308. David Tubb may have used IMR4831 with Sierra 250-gr HPMK's in his .308 for long range matches.

I did with H4895 during my squirrel craze, but not with 4831.
Explosive.... THATS expansion.

I've shot those 30 carbine bullets from 30-30 and 30-06, and they just never achieve great ccurracy for any distance. They do their best at reduced loads, like 200ofps or less. It's been a long time but i think I was uisng RE7 and IMR4198. If you are looking for a lighter long range varmint bullet, a 130gr psp or something similar will get you closer to where you want to be.

Or the Sierra 110gr HP, which is what I eventually settled on. Also, very violent in the expansion department. Can be shot north of 3100 FPS with MANY powders.
