I got a great deal on 6 lbs of 800x powder. I am just now working up loads. One thing I noticed though. I am starting at 9.4 grains for a 180 JHP. Given the few loads I could find I figured this would be a good starting point. 10.2 is listed as max but 9.4 looks like it'll be compressed let alone 10.2. Can anyone verify this is a safe starting point. IMR has one load for 180 8.7 grains for 1200 fps. Much too vague to be any help. Handloads.com and a couple CGNs (can't remember who...) are the source of my starting point. Any input is appreciated

PS the powder was made in 1989, if that matters. I thought maybe data could have chnaged due to lot variations over the years?

One thing to be careful of: 800X is really big flakes. I had problems with consistancy out of the powder measure on my Dillon 550. Not sure if that applies to your equipment or methods, just be aware.:)
 
9.2 Sounds right for 800x. the start loads for 40 is 6.0 for 180gr bullets and it fills the case up as well.

I picked up a couple pounds recently because it was really cheap. I'm trying it out in my 40s&w and 45. I haven't tried it out yet but it's a real pain to hand weigh every load. Hopefully it's all worth it.
 
I quite like 800x and for some reason I find it meters better than smaller-flake powder like, say, Green Dot. Been using 800x in some .357Sig loads recently.

According to the load data I quoted in that other thread, 9.4 sounds like a reasonable starting point, but I would add it depends on what gun you're shooting.

...On second thought, given my recent experience using what I thought was a safe mid-way starting load in .40 and almost blowing my gun apart, I would recommend loading two or three rounds at or near minimum just to get a feel for where you're at on the power scale. Specially considering the date of manufacture.
 
With 200 gr. XTPs I have shot up to 9.6 gr of 800-X. With no problems. S&W 1006 and Witness 10mm's.(always start 2 gr. lower and work up)

Like stated above these were individually weighed charges.

I don't shoot those loads all day long.

I usually shoot BlueDot as it meters better for me and is a nicer target load.

There is a wealth of info that Mike McNett from Double-Tap that he has developed using various powders for the 10mm on this forum. Check it out you won't be disapointed.

What was your mishap with the .40?? I don't recall reading about it.

Well, I didn't write about it 'cause it isn't particularly interesting, and also probably 'cause I was so pissed at myself I didn't want to acknowledge it.

(sorry for the thread hijack B) I got some 155gn. Cam-Pro CMJ bullets back in November and gathered the following data for Power Pistol (150 in parentheses means the data is for 150gn. bullets):

Nosler(150): 7.0/8.0
Speer: 8.0/9.0
Hornady: 6.2/8.6
Lyman: 7.0/7.8
Lee(150): 7.6/8.2
Other source: 6.2/9.0

I've been successful in the past starting in the mid- to high-range and have found that data in the Speer manual, though usually higher than average, was often more accurate.

So I loaded one box at 7.6gn. and another at 8.2gn. Didn't bother loading "trial rounds". At the indoor range, I loaded a magful of the "softer" recipe and shot one round that rattled the hell out of my poor P229. I then removed the mag, cleared the chamber, swore softly to myself and went home.

Thought I was gonna have to pull 99 bullets, but then I decided to shoot the rest out of my S&W610 in -10 degree weather. They had more kick than factory 10mm ammo.

All this to say I've since changed my approach when loading entirely untested components.
 
Glad to hear you weren't hurt! If 350 is using 9.2 for 200 grain 9.4 sounds reaonable for a lighter bullet. I am going to make up 5 rounds with only say 8.8 grains and run it through the chrony first to get an idea where I am at. Thanks for the reassurance guys.
