Got a new spring from H&R today, and two more are on the way.
Put the gun back together and tried a few primers. I could tell when I put the new spring in that it was much stronger then the old one.
The primer dimple is a lot deeper than the old spring, with the enhancement of the firing pin impediment, the fire in the hole is positive now. God, these misfires were driving me nuts. The soft hammmer fall would also give eratic ignition. Perhaps now after I repristinated the rifle I can get it to shoot halve decent again.
