800x powder measuring

Rigormootis

What sort of variation are you getting with the 800x through the measure?

I have been running it through my Dillion and accuracy is good, but I have not really wanted to check the variation...gotta be ugly with those giant flakes (at least it should be).

Iv'e got to chrono some loads pretty soon and that will tell the story I'm sure.

Whats the best measure recourse....go to a taller/smaller powder column (rather than wider shorter column?

regards

Paul

Hi Paul.

When my column isn't nearly full and I forget to tap it before the throw, I have been off as much as .2 gr. To me (and I assume most others), that's WAY too much. The recently installed baffel helps, but I haven't come to trust it yet. Under the best conditions and when I'm doing my part, It's much better...but I have resorted to weighing each charge now when I use 800x. I haven't completely given up, but since my mother-in-law is bugging me about what she should get me for X-Mas (bless her soul ), I have been seriously thinking of hinting towards a electronic scale/dispenser.

IMR Powder data...

Rigormootis

Sorry, I wasn't very clear...what I was wondering, was if the diameter of the metering bar (column or cylinder or what have you) made any difference. I know that large diameter bars can be a problem for smaller charges and if I remember right, thats why you want to use the small bar for the smaller charges in the Dillion, to help with consistancy. You could use the larger bar and reduce the chamber area, but it just doesn't throw as consistant. Also why you want to use the RCBS pistol measure head, rather than the rifle head....same reason.

But I haven't messed with the 800X that much to see what kind of difference it makes. As large as the flakes are, I am thinking it will help some, but that it will be good enough, I don't know. I am using the small powder bar now, in my Dillion for the 10mm but I bet it's none to good due to the flake size. I DO watch for a powder bridge with 800x...I think you could hang a charge or part there of, with this powder. Possibly not, but I wouldn't want to bank on it.

Your probably right in saying the best solution may be the electronic settup.

Sounds like a very nice mother-in-law....that's as good as it gets !

Got it. I actually am using the smaller bar...but the combo of it and the baffle does actually seem to be working better. To some extent, I am also just looking for a new toy. Yep, my in-laws are pretty great.

Shot some 180gr XTP's over 10.0gr of 800X and CCI mag primers out of the new 6" Storm Lake barrel in the G20 today.

Temp was 85 degrees, 2100ft elevation.

30 round average was 1420 fps. If my math is correct that equals 806 fpe.

No pressure signs at all.

1420fps?

That's a pretty ideal velocity. I know that the supersonic/subsonic transition doesn't matter as much for these wide, heavy bullets, but that's still supersonic at 100 yards

Shot some more rounds today out of the 6" Storm lake barrel.

Elevation 1800ft, temp was 89 degrees.

180gr XTP over 10.5gr 800X and CCI mag primers. Only shot 5 of each.
1460
1439
1454
1469
1482

200gr XTP and 800X

9.0gr
1305
1317
1268
1278
1292

9.3gr
1328
1306
1306
1317
1312

9.6gr
1379
1335
1403
1395
1378

The 9.3gr load was the most accurate at 25yds. All brass and primers showed no signs of overpressure. The Storm Lake chamber give the brass little opportunity to expand due to its tight tolerance. No such thing as Glocksmiles with the Storm Lake barrel.

Nice job !

Darn it's hard to beat the performance of 800X

I too have yet to get smiles out of my Storm Lake barrels.

Takes a lot of the worry out of it for me.

thanks Lenny

nice data

Yea, the 9.6 gr averaged 1378fps and 843fpe!!! That's a pretty darn good hunting load in my eyes.

It was a joy to shoot today. Even with a 22lb spring the brass went flying about 15 feet. Guys next to me were getting a bit on edge with the blast and brass flight.

I take it the accuracy remark dealt with the 200gr. XTP.

What kind of accuracy did you get with the 180gr. XTP @ 10gm 800X?

What is your most accurate 180gr. load?

Thanks
Jim

P.S. I am thinking little parachutes for the ejected brass would be good. Mine goes 15 to 20 feet from my EAA Witness. I like the all steel feel at these levels.

175gr Silvertips

First time working with 800X and I like it, seems to soften up the muzzle flip.

G20 6"KKM, Win 1x, WLP, 10.1gr 800X, COAL 1.258", 90F, 50%+ RH (monsoon coolness with more humidity), 4200ft:

1398fps MV, 759fpe ME, ES 37fps, SD 13fps

No primer or extractor marks with 22# Wolfe spring; however, the steel recoil rod drops down one notch on the KKM barrel and I don't know why.

My steel recoil rod drops down a notch on my factory and stormlake barrels. I'm pretty sure the factory rod does too. I just thought that was normal.

Lenny, do you have any idea what the pressures are in that 10.5gr/800x are running? It's got to be something like 45,000psi. Time to start looking into a .41mag maybe??

Witness Steel Fullsize 10mm

Finally got out to the range with the new chrony.

It worked well but I found I had to put it about 15 feet out so MUZZLE blast would not read....had a coulple of readings around 2200fps would be a nice veloctiy though for a 200 gr XTP out of a 10mm :blink:

These were all individually thrown charges then trickled off to get exact measurement.

Anyone trusting 800X through a meter and not weighing every single charge is asking for SERIOUS trouble......some of my thrown charges were 1 gr more than the average!!

Anyways here we go.

Witness 10mm Steel Fullsize(factory barrel)
Starline brass(new)
200 gr XTP
Imr 800X
1.258 OAL
CCI350(MAGNUM PRIMERS)
Lee Factory Crimp die(light crimp 1/2 turn)
43 degrees cold and windy.

8.8 1168(HI) 1103(LOW) 1132(avg)

8.9 1196 1119 1142

9.1 1174 1145 1160

9.3 1189 1149 1163

9.4 1203 1158 1173

9.5 1218 1182 1200

9.6 1228 1181 1210

None of the cases had any flattened primers. No excessive bulging either. I may try a .1 or .2 gr more but my absolute max will be 9.8. As stated before Mcnett's 10.0 gr load was in excess of SAAMI max and I will not even try it.

I fired off a total of 50 shots most grouped in about 3 inch circle 2 inchs above Point of Aim.

Still have a few FTF but this has greatly improved with tweaking of magazine mouth.


Witness 10mm Steel Fullsize(factory barrel)
Starline brass(new)
200 gr Montana Gold CMJ(complete metel jacket)
Imr 800X
CCI350(MAGNUM PRIMERS)
1.258 OAL
Lee Factory Crimp die(light crimp 1/2 turn)

I started this load off at 8.0 gr. but never chronoed it until 9.6.

9.6 1180(HI) 1173(LOW) 1178(AVG)

9.7 1225 1179 1203

9.8 1233 1183 1208

I had better cycling with this bullet and once again no flattened primers or excessively buldged cases. I may try 10.0 gr in this bullet because quite a bit shorter than the XTP.

This is my first experience with Montana Gold and they seemed to work fine at near maximum loads. Accuracy and grouping was much the same as the XTP.

I thought I might get a little better velocity than these numbers because I think the stock barrel on a Witness is actually 4.75 inchs which is slightly longer than on the Glock 20 factory barrel.

The lack of performance was probably due to colder temperatures?

The Lyman #55 dispenses 800X consistantly, just use a shallow setting for drop rather than a deep setting. I still measure individually on workups, but I found 800X consistant enough to measure every ten rounds for inventory; which is almost gone.

I may have some 200XTPs left so I'll try your recipes.

I was getting REASONABLE consistent metering with my RCBS Dandy little powder measure.

I used it for some practice rounds loaded with 8.0 gr of 800X.

To be safe though when doing the top-end loads I measure every throw individually...not like you are going to shoot MAX loads all day long...

One day I am going to invest in an electronic powder dispenser...

Anyone have 800x Data for 165 GDHP's? The new speer manual does not have 800x data, I may switch to AA#9 for this round and use my 800x for my 200gr XTP's.

Whew! Finally!!

Today I finally got to shoot some of my first ever reloads for the 10mm Auto. I have a G29 with 4.2" Storm Lake barrel.

I was able to shoot up to 10gr's of 800-X with no bad signs/symtpoms at all! (I shot 10 rounds and all the brass looked like the brass from my 7gr loadings, except more dented from the harder ejection).

Truth be told, I am amazed at how much of a ***** cat the G29 is... I was expecting the recoil to be much more than it turned out to be. It was almost pleasurable to shoot. Maybe it's the 21# Wolff spring helping that :D

Anyway, I'd like some ideas on velocity from at 4.2" barrel and the loads below or similar:

Winchester Brass - CCI LP Magnum Primers - 200gr Hornady XTP bullets - IMR 800-X - 1.26" OAL:

200gr & 9.3gr
200gr & 9.6gr
200gr & 9.8gr
200gr & 10 gr

(I shot all these loadings and more today... no problems at all.)

Note: Brass was brand new
