Probably getting a bit more vel with AA#9. I still like BD in the 10mm, one of the only reasons I still have it on my shelf. The more I shoot AA#9 though the more I like it for the accuracy. Not sure what I am doing wrong with 800X, but I never have gotten great accuracy with it & the weighing every charge gets old quick.I have not loaded 10mm in a while. I started putting some 200 XTP loads together over the weekend. I ended up using my old stand by 10mm powder again, Blue Dot. To me Blue Dot felt like it was a little softer shooting than AA#9 with top end Book Loads.

100% agree point by point. Blue Dot has been great for the medium warm ammo for all bullet weights. Tons of load data, great for the new 10mm loader. It has big swings on velocities since it doesn't meter superbly, but the velocity swings don't seem to show up on paper at handgun distances. It burns REALLY clean when loaded warm. Filthy dirty at moderate loads. Blast and flash! Oh my! You know it when you're shooting Blue Dot!Probably getting a bit more vel with AA#9.

While I don't dislike 800X, I was never able to get anywhere near what some are loading without brass shear.My experience with 800-x was like yours except that I had some spooky pressure symptoms on top of it.
Agree. I Think most that have worked high pressure 800x loads are just getting lucky. I have gotten the vel but not the accuracy I want. Since no one has put out pressure data I am aware of, I'll not buy more, just wasting my $$$.While I don't dislike 800X, I was never able to get anywhere near what some are loading without brass shear.
Maybe it's the tight chamber, but I found my stopping point well south of other's max loads.
After almost a year off I'll be testing with my Pressure Trace this spring / summer, should be interesting where 800X loads end up.Agree.

Cool. Been wAnting to get one but imo, Need a tc to do the testing. What are you testing with?After almost a year off I'll be testing with my Pressure Trace this spring / summer, should be interesting where 800X loads end up.
I built a platform that uses interchangeable barrels. The first two, a G20 LW with the chamber turned down & and an AR, provided low, but consistent, readings.Cool. Been wAnting to get one but imo, Need a tc to do the testing. What are you testing with?
Good stuff. I was thinking custom tc bbl in 10, have it made as a 5". Keep me posted.I built a platform that uses interchangeable barrels. The first two, a G20 LW with the chamber turned down & and an AR, provided low, but consistent, readings.
I purchased a 4140 Green Mountain .40 blank a while back, just need to have it chambered.
The 4140 barrel should provide more realistic numbers vs. the SS LW & Kaw 4150 barrels.
Another advantage to AA9 is that it is a flash suppressed powder. 800x seems to be a popular powder among those who like to load beyond published maximum pressures. This is likely because it's not a very slow burning powder and will produce excessive pressures when loading beyond max.Probably getting a bit more vel with AA#9.

11.0 should be a fine starting point. Hopefully the 150 gr Noslers work better for you than they did for me. They were undersized in the couple of 250 count boxes that I've used. Sized .399" or a hair under. My G20 doesn't shoot undersized bullets well at all. 155 gr XTPs are .400" on the nose so MUCH more accurate in my G20.I see a lot of info on 155 grain bullets so I'm thinking using it for 150 grainers shouldn't be a problem? Looks like 12.0 of BD is Max so I'll start at 11.0 or a little more.
