My girlfriend hunts with the 100gr TTSX but I am looking to load up a bunch practice rounds with much cheaper 100gr Sierra BTSP. Has anybody found that the .25-06 shows a preference for H4350 or H4831 with the 100gr's? I have to buy powder so I would like to just grab two pounds of one kind find the charge the rifle likes and load them all.

Thanks

My Steyr Mannlicher 25-06 loves IMR4831 with 100 (Bt and flatbase) and 117 grain Sierra BTs. Its the most accurate factory big game rifle I have ever owned, or ever expect to.

Oddly, the two loads shoot to the same 200 yard zero and the same drop chart to 500 yards.
 
Tough call without some real experience. Both are Extreme powders and both are recommended for the 25-06. H4350 is the faster of the two so it's probably where I would look if you don't get any concrete answers.
 
Repeatedly, the best results in my Savage 112BVSS

is with IMR 4350 'pushing' a 117gr Sierra BT. The C.O.A.L. exceeds the suggested maximum as I did so for my rifle to minimize the freebore. Pardon the home made target:p.

Just started working up a load with Hybrid 100 and the 100gr Matrix RBT's. Not even close to being done yet, but the first loads are looking pretty good, already grouping under an inch and 3050fps in a Marlin XL7 "cheapie".
 
As mentioned by other posters, it might be worth trying IMR 4350. I've had very good results with it for 75 gr V Max, 87 gr soft point, and 117 gr TSX in my Tikka T3.
 
In my experience about 52 grains of 4350 will give the best accuracy at about 3200 fps, but H4831 will beat it by at least 100 fps.

Even better is 57 grains of RL22 (work up!) for real close to 3400 fps.
