I ran across a couple of charge bars that are NOT bored for powder bushings and I can not find any information on them on the MEC website.
One is for a progressive and one is for a single stage.
Progressive - 12 GA. 12 500
Single Stage - 12 GA. OH
See pictures below. Anybody have any idea. If not, I guess I will throw the progressive one in my 9000 and weigh the results. I don't have a single stage loader.
I have seveal of the old bars and I had a person ream them out in a shop to insert the powder bushings. I had to use the old charts to find out which shot load they used.
That old OH bar will throw more grains of the new powder. It will drop about 19 grains 700X vs. the 17.5 it was designed for. Newer powders are cleaner and more dense. I've got a 0 bar that drops about 21 grains of Red Dot.
A friend came across some of these a while back and took them and a bushing to a machinist friend and had them bored to accept the bushings. Just another thought.
MEC sold bars for many years before they finally came out with the powder bushings. As mentioned above, they can be drilled out. I have a couple I've drilled out to accept Lyman powder and shot bushings. I've rarely used them after the MEC bushings became available.
