Can't find any 4350 or I would be giving that a whirl, so using RL-17 in all these load work ups. 2700 with 210s and 2600 with 225s and I would be stoked out of a 20" barrel.
Im getting just over 2600 fps with 225 grain out of a 24" tube with H4350. You might get there with Rl17 but even if you only hit 2500fps that's still a hell of a hammer.
