Paul, there is a reason for the issue with that pellet sizer, as I have found.... I'll try to sum it up, although it is involved.
It's all about the initial set up of the die vs.head size. When you think the die is adjusted right, it truly might not be.
We get the proper head size of a pellet, and adjust the die to it. We drop the pellet in, and it resizes future pellets. THAT'S the problem.
To set the die up properly, this is what you have to do:.....
First, using a Pelletgage, or Air gauge, find the head diameter that you prefer. Get a few of them. Then, cut the skirt off. Yup, you heard that right. Cut it off. You then need to find a material (usually from a hobby store, plastic, brass, aluminum) the same diameter of the barrel that is left after the skirt is removed, to ensure the head of the pellet is aligned with the die bore. There are several reasons you need to do this.
The first is to insure the head of the pellet makes it to the point where all other pellets are properly sized. By removing the skirts of the setup pellets insures this. This is so a skirt does not falsely hold back the pellet in the taper during set up.
Your die is now set up for the proper head size/skirt ratio. BUT, you are not done yet.
. You still NEED to check ALL pellets for proper head size. If you place all pellets with the head size that you want, and larger as well, when you go an resize them, they will all be uniform. All other smaller ones need to be put in the plinker/non match use pile. The smaller head size will give a false "feel" of being resized, if this step is not taken. The skirts are the only thing that will be uniform, if measuring head size is not done first. You will never know if the head size is proper, just by the feel. This is why you need to measure head size for ALL pellets before you run them through the die.
After that I roll tthem, to make sure the skirts do not wobble as well.
In a couple of weeks I'm going to post a U Tube video on the entire process.
Hope this helps.....
