Just fill the case up with powder, brush it off level with the palm of the hand, then seat a bullet!

I'm sure my pal Tryg H_ used to load his CZ-550 like that: kicked like a mule!

The recoil issue with the Ruger No.1 is light weight, pure and simple. If you can make the rifle weigh the 'proper' amount, and I'm talking 12 or 13 lbs (..or more!) for the .577 Full Nitro, then it will be comfortable to shoot.
