Just got my new to me 597 22 Mag back from the gunsmith: Volquartsen trigger hammer and ejector and new Redfield 3-9x40 scope. Going to the range tomorrow to try Hornady Critical defense, Hornady Vmax, CCI VMax, Win JHP, Rem Premier 33g Accutip and Remington 40g PSP. Going to find out what load it likes best. I use the Critical Defense in my 22 Mag revolver, but thought the bullet maybe good on large varmints/predators give extra weight and bullet designed to penetrate heavy clothing.
