Just picked up a Vanguard S2 Weatherguard and wondering if H1000 or IMR7828 would be the best powder to try. Would be loading 100-120gr for deer.
 
Both good choices. See which one shoots best.

The 257 Bee is way overbore so you can go slower burn rates than these 2 if you have anything.

Shot some R33 in mine with 110 AB a while back and 3500 fps was easy with no pressure. Didn’t try going any faster; no need. Accuracy was 3/4 moa at 300 yards also.

Good Luck.
