10mm 200 grain Gold Dot Hollow Points being sold at Cabelas $28.99

i assume no malfunctions?  How was accuracy out of your Glock?
I didn't notice much muzzle flash from my gun and recovery for follow up shots seemed pretty quick but I only fired @ 15 rounds out of my SR1911.
+P .45 will leave a pretty good mark.

No malfunctions. Accuracy was fine, though I didn't bench rest it or anything. The quality was very good, as one would expect from Speer and their Gold Dot line. It just wasn't up to 10mm power.

Though I agree, 45 +P power isn't bad for defense. I know I wouldn't want to be hit with one.

Should not be that hard to achieve 1000fps in the 10mm with a 200gr. bullet with careful loading. I have some of the original Norma 10mm loadings. The 200gr has a velocity of 1200fps and the 170gr HP has 1300fps. I have shot these (though limited times) in my Colt Delta Gold Cup. I believe these original loadings by Norma were for the Bren Ten.

Speer says these are supposed to go 1,150fps. My antique Chrony says they around 1,120fps.  Recoil and muzzle blash are mild for 10mm.

I'm looking forward to someone with better equipment chronographing these and shooting some gelatin with them.

Except I was specifically thinking ~1350 FPS from a 6" barrel.

Average gain from 5" to 6" at the ballistics by the inch website is 33 fps.  The gain for the one 200 grain load was 41 fps from 5" to 6", but the average gain per inch for that load from 4" to 7" was 35 fps.  If we accept 1200 fps as a SAAMI max, 1235-1241 fps is the extrapolated SAAMI max from a 6" barrel.  1350 is likely possible with a cast bullet though.

Yes and no.  A specific powder I'm sure does hit 1200 fps at 37,500ish PSI with some 200gr bullet from a 5" barrel.  And with some specific load(s) of some recipe I'm sure the ballistics by the inch results ring true.  But I also believe there are at least a couple or so powders that will push a 200gr bullet closer to or just beyond 1250 fps from a 5" barrel when finally reaching 37,500ish PSI (this is pure speculation on my part).

This past weekend I worked up some 10mm loads in both my bone stock G20 (4.6" barrel) and bone stock G29 (3.78" barrel).  And just for velocity curiosity I also checked the loads in my bone stock G20 except with a 6" Storm Lake barrel installed.  For MY bone stock Glocks I'm leaning toward the 2 following recipes barring further testing with a larger round count of each load:

200gr XTP / 9.6gr IMR 800-X / Federal GM150M / Brand New Starline Brass / COL = 1.245", and
180gr XTP / 11.2gr IMR 800-X / Federal GM150M / Brand New Starline Brass / COL = 1.245"
[DO NOT ATTEMPT THESE RECIPES IN YOUR GUN(S) WITHOUT WORKING UP TO THEM STARTING FROM 1 GRAIN LESS AND WORKING UP IN 2/10TH GRAIN INCREMENTS WHILE PAYING CLOSE ATTENTION TO PRESSURE SIGNS, ESPECIALLY GLOCK SMILES IF SHOOTING A GLOCK.]

In my guns primers were mildly flattened with both loads.  All brass bulged to some extent in the bone stock glocks but not to a degree that alarmed me personally. There were no Glock Smiles until I went past both those loads. 

The main things I'm wanting to point out are the difference in velocities for the different barrel lengths and what velocity I might be able to reach with 200gr Gold Dots in my G20 with a 6" barrel.  All velocities listed are an average of 5 shots.  Energy numbers added as general information for inquiring minds.

200XTP G29 = 1230 fps / 672 ft-lbs
200XTP G20 = 1254 fps / 698 ft-lbs
200XTP 6.0" = 1329 fps / 784 ft-lbs

180XTP G29 = 1380 fps / 761 ft-lbs
180XTP G20 = 1422 fps / 808 ft-lbs
180XTP 6.0" = 1528 fps / 933 ft-lbs

The 200XTP gained 24 fps in .82" more barrel, 75 fps in 1.4" more barrel, and 99 fps in 2.2" more barrel.
The 180XTP gained 42 fps in .82" more barrel, 106 fps in 1.4" more barrel, and 148 fps in 2.2" more barrel.

Loosely I would say the results of ballistics by the inch are in the ballpark of my results above.  But I think there's a good chance I can push (probably over 37,500 PSI) 200gr Gold Dots at least very near 1350 fps in MY G20 with the 6" Storm Lake barrel installed without getting over-the-top crazy.  YMMV

Thanks Redline for your report, as 800X is a great powder with one exception...you must hand weight each and every charge.  Never been a problem as I hand weigh everything anyway.  Awhile back 800X got a reputation as being with what was termed pressure spikes.
This also coincides with the proliferation and use of the progressive press.

Your data mirrors mine fairly close as well as what others were doing using the IMR800X.  With the 200 grain projectiles, I stopped at 9.4 grains as I felt it was gave great performance without worries with most brands of brass casings.

Here is the original 10mm data for the IMR 800X
OLDER IMR WARNING

This is some of the ORIGINAL IMR DATA that has been revised especially for IMR 800X
It is placed here for study, and comparison and preservation purposes...
Consider yourself properly WARNED!



I know some who have tried the 135 grain bullets with the load listed above that made 1800 fps and some had their guns damaged from casing blowouts.  Therefore WARNINGS should be understood!

Please understand that this was my experience after I resized, re-expanded, reloaded as put that round back together to the same spec as taken apart...

[Intercooler]

I received mine today and will be Chrony testing them Sunday. The plan is to send a couple to The Shadow for pull-downs and The Chopping Block for his gel tests.

[Overkill338]

Anyone Chronoed these from a Glock 29 yet? With Underwood 200gr the 29 loses about 100 fps vs a 5" barrel. So I'm guessing probably 1000 from a G29. That's still a respectable SD load, anemic, but respectable.

Thanks. That is good to know. I have been measuring each charge, but only because I was only loading a few test cartridges and I was too lazy to set up my progressive press.

Looking forward to the results, especially what speed you get from a Witness.  Gonna test them through your hunter model too?

Thanks. That is good to know. I have been measuring each charge, but only because I was only loading a few test cartridges and I was too lazy to set up my progressive press.

800X + Progressive Press = A fair chance of disaster especially when loading hot to begin with.  I tried once setting up my progressive powder drop for 800X; the attempt ended in gross failure and I will never waste my time trying it again. It's crazy too, you can get 800X to throw perfect charge weights for over 30 attempts in a row and then all of a sudden BAM, a charge weight can be grossly over or under your desired charge weight.

By no means am I saying I don't like 800X.  On the contrary, for top velocity in 10mm, especially with heavy bullets, it ranks #1 or tied to it.  So for a few loads weighed one at a time by hand for hunting or whatever I'm all for it.  I'll just never trust it with progressive loading equipment.

[Intercooler]

Yup! Running both barrel length Witness 10's. I didn't get to shoot all Summer. This will be a big session!

[Intercooler]

Always love how the Witness pistols shoot the 10's. Such fun and just great shooting 

EAA Limited Pro 4.75" barrel 1068, 1072, 1086. Average 1075.33 FPS/ 514 LBS
EAA Super Match 6" barrel 1128, 1100, 1096. Average 1108 FPS/ 545 LBS

Not real barn burners, but should work pretty well.

If we can only find someplace selling them for less than $1.50/round.

I'm curious how they'll do in gelatin but Speer seems to do a great job crafting bullets with little gold dots in the hollow point.

[Intercooler]

If we can talk Chopinbloc into running them
