    Blue Dot for 9mm

    I have a friend in Atlanta who is new to reloading. He has a Dillon 550 and is useing Blue Dot in a 9mm case with a 146 jhp. The blue dot is a compressed load according to him. When he shoots it the load will not fully cycle the slide. He tells me that it is the same load another friend of his useing. I would think the powder would be too slow. I have have loaded for 25 plus used it in a 44 mag.and it works great.THANKS FOR ANY HELP Tom.

    IMO Tom - Blue Dot is too slow a powder for this high pressure round - case capacity is too limiting too. I doubt anything slower than Unique is worth considering and in fact the fastest powders such as Bullseye and N-310 etc are probably the best bet - great care of course with charge weight and seating depth.

    I do still use N-340 which was a powder recommended for 9mm - and is a smidgeon slower bit still fast enough to do well without bulking problems. I fancy it lowers the peak pressure a tad. I don't tho use heavies like 147's - usually stick to 124's and the heavier bullets will also reduce case capacity a little too..

    Blue Dot is way better kept for light mag loads in bigger cases.

    I used to use Blue Dot in 9 mm with a 125 grain jsp; between 7.5 and 7.8 grains, with good results. I use Unique in 9 mm now since it works in .45 ACP and .357 "cowboy action" light loads too - simplifies life.

    The Speer manual and the Alliant manual / web site list 8.2 grains Blue Dot as a max load with 125g jacketed bullet, in 9 x 19.

    If your friend loads primarily .357 mag and 9 mm, Blue Dot may be a good choice for him.

    Never take loading from word of mouth!! This is just asking for trouble. I load within the limits of published loading manuals. For my 9mm rounds I have had great success with both Unique and Bullseye.

    to me #5, titegroup, unique and bullseye work best for my 9mm reloads. never used blue dot in anything. i would look at different reloading books to see what is the best starting loads. reloading books will get you in the ball park, then you need a chronograph to get the real story. they are cheap and good insurance if you do a lots of reloading.

    Blue dot works great in the .44 mag. I won several matches using a light load with SWC bullets shooting against guys using .38s with wadcutters. Extremely dirty powder though.
