ok, sadly I stand corrected. these rounds will also do the same thing. and are harder to get something behind to push into the mag tube. oh, an once in a while, a second round will be partway out of the mag tube getting in on the jam also. I bought my first rifle over 40 years ago, have done dozens more since, and at this point in time, this is my biggest case of buyers regret. this may be headed back before my warranty card even makes it in.
