Magazines are next to new Browning , not the originals that came with it. Also have the calipers as I load for quite a number of cartridges. Dummy rounds loaded while determining a COL strip from and feed into the chamber properly. I also did the plunk test in to the barrel to check fit that way. With the empties not clearing the port, it leads me to think not enough energy yet at the 4.1 charge. I'd have to double check the book but I think the Hercules manual, perhaps 1992, is listing up to 4.9 as a maximum charge with a 124 FMJ. I'm not loading anything unless I can find data in the books or at the proper loading guide from the powder maker.

I do have some BE86 and have loaded up a series of test rounds and will try them at some point on a decent day. If the change in powder makes the difference, I'll save the Bulleye for another time. Thank you for the observations.
