I went to my local range in france this morning to see what results i could get with h4831sc in my .243. I first loaded three rounds with 42gn these produced a group about 1 inch, next was 43gn these produced a group again about an inch with two shots touching, next i tried 43.8 this opened up the group to about one and three quarter ins , I used a lee loader to give the barrel time to cool, it attracted a lot of attention and i had quiet an audiance. Next time i go i will load 43gn and alter the length from 2.65ins to see if i can improve the group,
Cheers Geoff
