I modified my Ruger 10/22 with a Hogue rubber stock, took it to the range. I was getting a jamb after the 6th or 10th shot, sideways stove pipe jamb, this rifle had been very reliable with the cheap factory wooden stock. Found that the magazine was under pressure in the magazine well, used a file on this area to allow easy ejection and movement of the factory 10 round magazine. I usually use lead tipped medium loads for all my .22 rim fires. I also tried using another magazine as well.
Have taken it to the range twice since and occasionally get the stove pipe jamb, but things are better than before. On my last trip I brought along different ammo, thinking there might be a sensitivity issue now, perhaps some squeezing on the action? At first my CCI ammo was jamming, then switched to the expensive Remington Target Rifle ammo made by Eley. Why Eley puts the Remington name on their ammo is beyond me. Fired the whole box without a single problem. Then put some more CCI medium loads through it, no problem.
I wonder if the gun was simply over greased, and was getting a buildup inside the action and the ammo working the bolt through it smoothed things out? Or, is this gun now ammo sensitive, requiring expensive ammo like Eley to work 100%? In the old days we would use high velocity ammo to deal with a fussy gun believing that the greater powder charge would hammer the action more to make it reliable. My other Ruger 10/22 has the fancy laminated target stock from the factory, it will eat anything I put into it, and it gets oiled and greased like my cheaper carbine model.
Has anyone else found their gun to change it's ammo eating habits after putting a new stock on it, and will high velocity ammo fix the issue?
Thanks.
