need info on H380 and H4831sc

[hunt_4646]

I have obtained a rifle in 270 winchester that does not like my old faithful loading of IMR4350 55.3 gr with 130 hornady soft point bullet.
What is the experience with H380 and H4831sc in 270 win?
Has anyone experience with these powders in 243 win or 7mm-08rem?
IMR4350 and H4350 have been my favorites in hunting loads for deer in 270 win and 243 win, but not opposed to trying different powders. I will stay with 130 grain bullets in 270 and 95 or 100 gr in 243.

I have had good experience in the past with a mx load of the regular H4831 (not "sc") and 140gr bullets. The SC is just supposed to meter better, and some say that it is more consistent.

H4831 is considered by many to be THE 270 powder. RL 17, 19, and 22 are good ones as well.

Don't have my book in front of me, but I am somewhere between 58 and 59gr of H4831SC with 130 grain bullet in my Browning .270. And H4350 in my .243 with 95 grain bullets.
