Hi All,
since I've gotten my MEC sizemaster I've done up my first 1k rounds - most have come out perfect and I've been on something of a learning curve.
My question now involves the resizing portion of the process - I took a few hundred rounds to the range and found that all rounds would fit in my 1939+/- vintage gun but would not fit in my 1984 H&R Topper. The barrel would not close without what I would call "excessive force" - to the point of jamming the shell into the chamber and extracting via cleaning rod down the tube...
my question:
What is the proper procedure for sizing/depriming in the sizemaster?
I've operated the machine according to the instructions but have noticed a "ring" near the base - about 1/8" from the base of the shell. It actually appears to be more of a flare from the rim up along the base...
I'm worried about the shells not being suitable for all 16's, not just my own - including my H&R
Is there an adjustment to my process or machine I need to make in order to get the bases uniform?
Thanks All,
Sprocket |

Hello, Yes there is an adjustment possible on the collet of the sizemaster. First a couple of questions.
1. Is there a removable "T" post at the bottom of the collet. Use a magnet and see it if comes out. It should be there, but sometimes when the presses are moved, the post falls out.
2. When the press handle is depressed all the way down, are the collet petals touching? Yes is good.
Now with those two ideas out of the way, there is a nut on the bottom of the collet, it can be tightened to increase the sizing of the hull, but adjust VERY slowly and try hulls to see what you get and if the nut is too tight.
Let us know what you find. Enjoy the day, Mike |

OK - so that solves the mystery of "Where does this flanged tube go"...Now to figure out the rest of the "spare parts"... 
Problem solved - thank you for the quick reply. |

None taken, it's learning experience.
So what else do you know?  |

You also want to keep the collet clean & lubed.
MEC sells a Anti-Seize collet lubricant  |

gentlemen. thank you for this post. I too just got a sizemaster. the post was not in the collet and I had not idea it went there. Of course the hulls had the ring around them.

No other issues really other than the usual time to feed it, etc.
I've had some issues with crimps but I figured it out.
Now that I've got it running smoothly, I'll be working up some non-toxic loads for the fall |
