I'd start with RL16, H4350, RL23, RL26, H4831.

IMO h1000 is slow for that bullet weight even in longer barrels.

I realized I never got back. Here is the load I went with.

Berger 168gr. VLD Hunting
56.0 gr. of H4350
.30 off the lands
Federal 215 Primers

My velocity ended up at 2775 FPS and the holes on a 3 shot group where touching at 100 yards. Not bad for an 18 barrel.

Another one for H4350.
