re: Problem with a 444 Marlin not firing?

Had one miss fire on me this weekend, i pulled the hammer extension of to lessen the weight on the hammer and also replaced the spring with a heavyone for more pull. Worked good for a box of rounds then did the same thing, not hitting the primer hard enough. Gun smith said the breech plate may be mis aligned lettting the round fall to far forward, he is sending it back to H&R, its a common problem.
