Hodgdon LEVERevolution Smokeless Powder 8 Pound

Was looking for a new powder for my tricky to reload Remington 700 257 Roberts as I am constantly working up different load combinations. H4831 is my standby but H100V seemed a likely candidate looking at burn rate charts. Like others I was surprised how fast H100V felt when using published loads and was disappointed in accuracy. I was going to give up on H100V but I normally use lighter loads for reduced recoil and improved accuracy so working down to 40gr for 100gr bullets, group sizes reduced like magic by more than 50% and I’m approaching my old H4831 best loads. 40gr is well below the starting load. 46gr H4831 and 40gr H100V have about the same point of impact. It appears that 100V is not weirdly fast but has better pressure regulation so heavier loads can be used. It may be just my particular combination, but if you have had mediocre results with H100V try reducing your charges.
