Havent used MEC bushings on any of my reloaders for years. Just bought the new MEC 9000E electrick reloader and decided to use their charge bar instead of the Universal Bar I normally use. To load 17.5 grains of 700X
the MEC Bushing chart shows to use #29. Didnt even come close. #30 & #31 didnt do it as well. #32 hit the 17.5 right on the head. My scale was zero'd. My question is: Is this large variation normal? Thanks. Bob
The Mec bushing charts seem to be based on the single stage machines. Everytime I used the same bushing number in my progressive machines light throws were the result.Probably because of less vibration in progressives. But a good scale and have faith in the scale. Les.
At least this guy has the scale and knows that an issue exists! I have seen guys load for years with nothing but a bushing chart and faith. They are always amazed when you tell them that approach can be problematic. Jeff
I was loading 19.0 gr of 700X with a #32 bushing. When I bought a new 8 pound jug I checked the weight and had to drop down to #30 to get 19.0 gr. Always check with your scale. The charts are worthless.
Thanks for the replies. I can't imagine anyone using a reloader without a scale but I guess it does happen. My normal pattern is to check about 6 to 8 powder drops before I begin reloading. Periodic check after that. Bob
I talked to MEC yesterday to find out what size bushing I needed for a certain load.
The person said that they use a single stage loader to measure their bushings with. The single stage throws a more constant drop and progressive loader usually throws maybe a grain less than the single stage. Its because the powder is above the bar all the time when dropping the powder and is not a constant moving bar like the progressive bar. Both bars have to be moved to discharged the powder and shot?
I still use a Universal Charge Bar on my 9000G and to be truthful I think I'm going to s...can the c/bar w/bushings on my new 9000E and get another Universal for it. You might wonder why I'm keeping the 9000G? Until I get used to the 9000E (electric) and the two button push system to get it moving I had better just sit on the 9000G. On the 9000E had to call MEC yesterday to find out why I'm blowing the 1 amp fuse so often. Went though 7 fuses on saturday but evidently the fuse blows every time there is a mishap on the downward stroke such as a wad getting caught on the edge of a shell. The MEC Rep stated it is to protect the electric motor. Makes sence to me. Radio Shack here in So. California had the exact fuses as required by MEC. Bob in Los Angeles
