I've loaded with H4895 powder using a Remington 300gr HP bullet. It was packed with 57grs and had a listed velosity of around 2100fps(I think). trust me when I say you won't want to shoot this load alot. I had the bruises to prove it. I since switched to 41 grs of IMR4198 and just love it. Listed veloisty is about 1800fps and it shoots like a 20ga.
