May I suggest buying a heavy 22 target rifle...like an Anschutz, an old Kimber, or a Russian make. Put in in a pedestal rest, along with a rear bag --- and hold the rear of the buttstock --- about 1/4" off your shoulder; as many benchrester's do.
That rifle hanging on the wall of the working class flat or labourer's cottage is the symbol of democracy. It is our job to see that it stays there."
--- George Orwell
