Your experiences with 800x ?

As you found out, it meters like cornflakes. It will, however, give you high velocities with lower pressure than most other powders. It does well in the 10mm, but I've never tried it in any of my .44's, so I can't help you there.

Hope this helps.

It does have a good reputation for 10mm, but so many other powders work well in the 44mag. I've still got a few pounds of RedDot which didn't measure well either I'm trying to find a use for

I use it in 20 gauge shells.

I love it in both 10mm Auto and 44 Mag. As others have said, got to weigh each load due to how poorly it meters but it does well in heavy projectile pistol loads.

I have had excellent results with 800X in my 4" 629 and 7.5" SBW. I load it a tad below max load data and get complete burns. I tried working up some 44 special loads in my 2.5" Bulldog and found it it spit unburned powder...a lot lol!. So it don't do that anymore.

But it is actually one of my go to powders for my general purpose 44 mag loads.

I don't need to crank out 100s of handloads at one sitting and find hand weighing each drop therapeutic. Weird, I know. But true.

Be well

Most do not like it due to it's poor metering qualities. I found the answer with 700-X as it is worse IMO. After determining your load make a custom scoop out of an old brass. I use one that has split of the same caliber (44 MAG for one) and a piece of copper wire soldered to it. I fill the bottom with epoxy to just above where I think it needs to be and calibrate the cavity by using a drill turned by hand that is just under the mouth size to remove small amounts until it scoops the correct weight. Never goes out of adjustment and is reasonably quick unless trying to do this on a progressive

I find 800-X can be used in a lot of places you find 700-X or Red Dot data for handgun ammo although not much is listed anymore. Older manuals from the 60's and 70's list some loads that I have used.

I'm an 800x fan. It is one of the most versatile powders covering a wide spectrum of uses. The widespread complaint is about the way it meters.....but I have found that it meters with adequate consistency in charges of 8 grains or more provided that press/powder measure operation is consistent in vibration and force. Plus or minus a couple tenths of a grain really is not a problem in those charges.

My loading logs remind me I loaded 45ACP with it in the early to mid 90’s 6.4 grains under a cast 200 SWC. Loaded on a Dillon 550. No problems indicated in notes.

it meters well in my chargemaster ha ha ... not in my dillon 550.

It does meter rough. But I have had good results with 10mm and 45 Colt. Be patient and go with it in those calibers.

Excellent in the 357 SIG some the highest velocity loads ... also a good 20 gauge powder ...

Yeah ...does not meter well .... but I throw close and trickle up .....

I mostly use it for 20 ga 1 oz field loads, but I’ve also used it for 38 special with lee dippers before I had a decent scale and meter.

I have no experience with 800-X but I use lots of 700-X in my 45 ACP loads and lots of Unique in 20 and 28 gauge loads plus various handgun loads.

My secret for better uniform loads is to throw about 20-30 loads from the powder measure before I even consider charging any cases. This seems to settle the powder column in the powder measure.

Also, the variability of the powder charges is a bit larger than you might experience with a good metering powder. It does not seem to make a difference in performance from shot to shot.

Follow published data from a reputable source, do what is necessary to get consistent charges, and have fun.

I like the performance in 45 Colt. In my Uniflow I get decent results, most drop +/-.2 grains. Using the large cylinder. If the drops start varying I break down and clean the measure. I also use magnum primers for a better burn.

800X in 10MM will get a 200 grain bullet moving fast but meters like cornflakes.

I have been thinking about getting a lb. of 800x to try in 357 SIG. I have been using Longshot along with some other powders, which have been good to okay. Being that I'm still new to the cartridge, I have to compare.

Long shot is my go to powder for full loads .....800X will extract slightly more velocity over Long shot at the expense of being a hard to meter powder ...really a "measure/weigh each charge" powder especially when getting close to maximum charges.... with 800X you can safely run a a 124 grain bullet very close to 1500 fps(4.5" barrel)because of 800X ability to keep peak pressure down over other powders ....800 X is not for loaders who will not take the proper time to safely use it.

Enforcer is another powder that is said to be much easier to meter and gives velocity similar to 800X ( not sure about pressure)

Thanks for the info. It will give me something to work on this winter.

Accurate #9 is VERY good in 357 Sig... Good case fill, bullet sits on powder which helps prevent setback... and excellent velocity.

AA#9 is the powder that makes loading the 357 SIG "easy" .... the normal load is a case pretty much full and is a slightly compressed load ...the bullet is held from set back by the powder.

For some reason #9 is not common here in the LGS... Long shot is ....

Enforcer and AA4100( the same powder I am told) are in the same burn chart area as #9
