Marksman pellets in .25 work well in older bsa barrels I have found and FTTs in newer barrels. Though I have also been considering getting a pellet sizer. It is actual possible to get s sizer to match the finer tolerance for .243 or do they size them to 6.35? I have found a pellet seater always helps to get a snug fit in the breech though.
