I have a large selection of boolit loob grooves for sale. On many of my boolits, it isn't necessary to loob each groove, so I have a box full of surplus for sale. There is a great variety of width and depths, so you should be able to find the perfect ones for your applications. Specs on all are within .0001. Of special interest, is a large amount for the rare Asperly Aimless loadings.
These have never been used, and are new in the box. I should be able to put thousands of these into a flat rate box.
Asking price is $89.99, plus shipping to your address. Overseas will be higher, of course. You are personally responsible for getting them through customs, and trying to explain what they are.
