any large rifle, or mag rifle will work in a pinch.
I would look at IMR-4895. SHoots very good for my dad and I in 3 different 22-250's.
Around 35g of IMR-4895 seems to be the magic number with 40's, 50's, and 55's. 1/2-3/4" at 100 yards and pretty good velocity, 4000fps for 40's, 3700fps for 50's, and 3675fps for 55's.
H380 is picky as hel in our rifles. Very small nodes to work with. Very temp sensitive. I dont recomend it.
For top velocity, W760 w/50's and 55's is worth looking into. I dont get as good as accuracy as 4895, but get a good 100-150fps gain over 4895, and still 3/4"-1" at 100 yards.
