Just got a Matador 25 cal R3 with the 9-shot magazine. Sometimes when I push the bolt forward , the gun misfires as the pellet is inserted into the chamber. I do not think I am placing excessive pressure on the bolt handle as I push it forward. Prior to this rifle I had a single shot 25 caliber Matador that I purchased in 2013. I never had this happen with that rifle. Has anyone had similar experiences with their R3M?
