Magazine problem?

[high_lander]

So I went shooting yesterday and had some issues feeding the JHP rounds in my RIA Tac model.

Through experimentation, I found I could only load 5 rounds of JHP before I would get feeding jams. Any more and I noticed that the rounds would dip in the front, and that would be enough to cause the nose of the round to catch on the feed ramp.

Is this just a magazine problem that would be solved by some 47Ds?

I ran PDX1 just fine through the 2 Novak magazines in my Tac. It was a hit or miss otherwise so I have since upgraded to 47Ds and havent looked back.
