16ga Lee Reloading Question

[boneandbass]

I have used MEC reloaders for years, and couldn't resist a bargain price on a Lee Load All 16ga loader. Lee is new to me, and I rarely shoot 16ga. I shot a box of Herter's and then tried loading. only to have the final crimp cave in deeply.

One of my regular trap shooting friends suggested putting a small piece of cardboard over the shot and then going through the pre and final crimps. It seems to work pretty well, but I question the process. Is it safe and what will it do to the pattern?

All input is appreciated, and thanks.

it's probably caving in because your column is a hair too short, perhaps because of a short wad. The cardboard overshot wad you added is taking up that slack. It should be fine.
But, for the experts (I'm not an expert) to give you a precise answer, they will all want to know what recipe you're using.

It could also be you're crushing the wad. Experiment with your press technique. The Loadall II needs to be pressed completely and firmly to the bottom of the stroke, but leaning on it can cause this problem. My LL II loads 16ga just fine.

Thanks for the input. What wad are you using? As for overall load info I'm using the 121 powder load (for Greendot) and a one ounce load of shot.

Thanks - look forward to learning more

Cardboard on top of the shot may open , and/or make holes in the pattern.

Thanks again. I am using Claybuster CBO-100-16 wads. Since this does appear to be a little to short, do you have a suggestion as to a taller one? What are you using?

Thanks
