So I got a NIB model 96 22 mag about 9 months ago and have had misfires with all types of ammo in it. The frequency has fallen off the more I have shot it and it happens about one in twenty now. I have pulled it down and cleaned all factory grease out of it and lighly lubed it with tri-flow. When the gun was fresh out of the box winchester dyna points would not fire 50%. Every shell has been struck and if the gun is re-cocked without extracting shell completely it has always fired on second strike. Any suggestions. I know rimfires are more prone to misfires but are 22 mags worse than 22 LR. One out of twenty is not an acceptable failure rate in a hunting rifle.
