It has the 1030 stamped on the side.

Edit: the original one had ML stamped on the side.

New new magazine box is going to require tuning for the 380 grain Lehigh Flat Points. It feeds the Hammers fine at longer lengths.

But, not the flat point Lehigh. The original ML magazine box has the upper forward corners angled inwards. This new one needs the same. Regardless of the numerous coal that I tried, feeding is from not happening to terrible at best.

The angled bends guide the fat flat point to center of feed ramp and feeding is smooth at the desired length, and longer or shorter. The ML box allows longer COAL than I will be using for this flat point.

I don't think adjusting the 1030 box will be too difficult. While still maintaining the longer coal to accommodate the intended Hammer COAL. We shall eventually see. A back up 1030 has been ordered. I have not been able to locate a ML box.
Meanwhile the ML box is reinstalled and flat point solids are the near future project.
