61 grains of H4831sc with a 130 grain Interlock gets me 3105fps out of a 23 inch-barreled BSA Imperial Featherweight, and groups just over an inch. It's a business-like load for a .270 and I don't mess around with it. The rifle was made in 1958 and it's like a British version of a Winchester pre'64 - only much lighter; a true featherweight and ahead of its time.
