I shot in a local NRA Bullseye League we shot twice a week , A fellow who was in the Army Marksmanship Unit would come and practice whenever he was in town. He had a model 52 , used it in competitions and let me shoot it on several different occasions . I think the trigger had been worked over by someone who knew what they were doing,
it was a sweetheart , get one if you can.
His experience was the HBWC ammo from Speer , was ever so slightly more accurate at 50 feet than his own carefully cast (Lyman 358091) solid base WC's . Not by much but a little, so he would practice with cast but compete in AMU matches with Speer HBWC.
I believe the Army furnished them loaded Speer target ammo , but even with his cast WC's and reloads we couldn't come close to his scores.
