Just getting back into reloading with the purchase of a new 16ga Browning Citori and I'm having some trouble with the crimp. Here's the data:
Mec 600Jr reloader
BPI Multi-Hull (new supplied with 209 primer)
BPI Sporting 16ga wads (7/8 to 1oz)
19grains of Unique
1oz of 9 shot
I'm using the standard supplied starter crimp (6pt) and have it adjusted to stroke as far as possible without collapsing the sidewall of the hull. In the final crimp stage, I have it adjusted to where it finishes without collapsing the sidewall, but the crimp then appears to have a swirled pattern instead of just a uniform "to center" looking crimp. The end of the shell is then sloppy as well. There is no crisp edge at the end.
Suggestions/help please? |

I've had that problem on my sizemaster. You have to loosen the cam adjust screw and move the cam up very slightly. Keep adjusting until you get acceptable crimps. If your press is new, your manual should outline how to do this.

For starters, compare the length of your crimped shell with the length of an
unfired shell, then adjust your starter crimp and final crimp to achieve a final
shell length equal to an unfired shell. A MEC 600 is a very user friendly
reloader. Although single stage and slow, its simplicity and ease of operation, with inherent inspection at each stage, makes it a very effective
reloader. |

| Thanks all for the replies...I don't have the manuals anymore, but adjustments are certainly easy. I will head downstairs tonight and see if I can put these suggestions into action. |

| Haa...success...I think....adjusting the starter to Mike's original suggestion makes for a pretty good crimp. I notice that the finished shell is clean and without ripples or collapsing, but it is approximately 0.060" to 0.090" longer than a factory Fiocchi shell. I can put a caliper on it for a more accurate measurement if necessary? Is this a problem? |

No, it's not a problem. You're main concern is a good crimp. Congratulations. |
