    Glad I started at the minimum load

    Looking up data for Blue Dot and a 180 grain XTP had charges all over the place. Starting around 9.5 to over 11.0 grains

    Started with loading 5 rounds in .2 grain increments. 9.5, 9.7, 9.9 etc. If the pressure got to high I wouldn’t have to pull a lot of bullets

    At 10.1 I had a slight bulge in the case head. Barely visible but I can feel it when I resize the brass
    I throw those out.

    Close to 1300fps.

    I know the Delta doesn’t have a fully supported chamber so I am not pushing past 10.1. Probably back off to 10.0

    Take a look at Hi-Skor 800-X. For the 180gr and 200gr bullets in 10mm it works really well while keep pressures down for your partially supported chamber. It does not meter well in a drop dispenser as it is a very large flake powder but if your willing to weigh each charge 800-X is an awesome heavy 10mm powder.

    I use 800x with my 10mm. It is hard to meter, but if you have a chargemaster or similar it is definitely worth a look. 180 Gold dots and 200 XTPs are my go to bullets. They can run up to a hair over 1300 fps in my G20 before I start getting too much "smile" on the brass. I have settled at about 1250 FPS to keep from overworking the brass. Plenty of speed and manageable to shoot. I also make sure to use the "hot loaded" cases only once, then low powered plinkers after that.

    I did consider using blue dot, and I think longshot was another popular one, but 800x did a good job right off. I never bothered to try another honestly.

    I have a 1911 10mm with no case support. AA#9 seems to work well even up around max listed data with no signs of bulging. Red Dot, Bullseye and Unique are all good just a step below that.

    BlueDot is my powder for my 10mm. It’s a RIA Tac II with fully supported chamber. 11gr is the load that works best.

    I load my plinking 10mm over .2 grains over the staring load. I trust my powder drop .2gr on either side and feel safe. This way in case I load an over loaded case or someone else's bulged but repaired case that I picked up I should be safe.

    Anything more powerful I hand weigh every load.

    Though I did just pick up a Dillon SDB and will test the powder drop with some 800x or #9 to see if I can trust it for the heavier loads.

    Good luck loading.
