Special Bullet load data (XPBs, etc.)
 

This is the thread to post loads with various company's powders for bullets that cannot be loaded with similar loads to other same-weight bullets, such as the Barnes XPB. Obviously, because of their construction, they have different loading requirements, so post these loads here.

7.8 gr of 800x and the 95gr .40 caliber mini-ball, with the 135gr Nosler JHP on top. CCI 300 primers.

This closely resembles the DT 230gr Equilizer (duplex) load.

I worked this load up very slowly, starting at 6.5 gr of 800x and working up .1gr at a time. My chrono won't function when two projectiles are firing through the screens. I think it'll do around 1125fps out of my Wilson CQB.

Other than Blue Dot flash, some smoke and a barrel requiring more cleaning than usual, am I pushing "Laser Cast" bullets too far with this load?

Laser Cast 180 grain TC with 11 grains of Blue Dot. Used CCI 300 LP primers, Starline Brass. Shot from a customized G20 - Lone Wolf 6" externally ported barrel, Wolff 24lb spring /SS guide rod, Wolff/Brownells competition spring set, Lightning Strike LP Trigger, and some dremel work. Here's chronograph data from three, five shot strings:

Tom,

Enjoyed your 10mm article. Good information. Never been a huge fan of the .45acp since my days in the service. Really love my 10mm's though! Mike puts together some great loads... XPB 155 is my favorite CC load.

"Doc" [-Jay]

I found 10mm data for the Barnes 140gr TAC-XP on loaddata.com. 11-13gr of #7 and standard LP primers. With 12gr at 1395 fps. I loaded several mid-range loads in 400 cor bon at 12gr that were accurate without too much kick. Not sure what velocity these 140gr bullets need to fly to be effective(compared to Barnes 155gr bullet.).Corbon DPX in 40cal(140gr) has a velocity of 1200fps. I heard that Double Tap is coming out with a 140gr loading in 10mm at 1500fps.

140 gn General copper bullets
 

8.6 gn of tite group at 1.250 = 1405 fps out of a glock 29 MAX Load

I posted this info in the reloading section in an effort to provide some specs for the bullets...
I had wrote Barnes about acquiring a few samples of the bullets listed below to study their physical characteristics, because I knew that the solid copper bullets where longer that the lead core counter parts...Below is the measured data of the samples received. I must commend Barnes Bullets and thank them for these very nice bullets...:wow:

After I do my load test I repost here...

Shadow, I just ordered some 125gr Barnes TAC-XP bullets, and it got me looking around for load data. I see in your post above that you list the bullet length for the 125gr as .720", and the 140gr bullet at .680". Is that backwards? I can't imagine the 125gr bullet being longer than the 140gr.

21Carrier the data for the 125 grain I lised was for the 357Sig bullets at .720" length "NOT the 10mm 125gr." Sorry if there was any confusion!

Barnes sent the 125gr. for testing in my 9x25Dillon project...

Ooooohhhhhh gotcha! Thanks. That was giving me fits. I was also wondering why the hell you'd be comparing it to a 9mm bullet. Thanks for the clarification.

Oops, Tammons and I have been sitting on this data for a week. I forgot to post it here. Here's Barnes's data for the 10mm 125gr and 140gr TAC-XP bullets:

http://i1104.photobucket.com/albums/...BarnesData.png

Here's some load data using the Barnes TAC-XP bullet, Power Pistol, one load of Unique, and a G29 (stock barrel, 21lb spring). Barnes' PP max is 10.4gr, Unique is 8.4gr. All of these were with Starline nickel brass, CCI 300s, and a COAL of 1.250".

CED ProChrono Digital, 91*F, 55% humidity, 495' above sea level, distance from muzzle ~10ft.

Here is some new data that I developed for the 125gr Barnes TAC-XP bullet. Out of my G29, I got 160fps MORE than ANY of Barnes data. The fastest I could get with Barnes data (Unique and Power Pistol) was 1300fps. With these 800-X loads, I hit 1460fps. Again, this is all out of my G29. I'm sure 1525-1550fps would be easy out of a G20. This load can almost certainly be increased. I do not think it is maximum. I ran out of bullets, and had to stop here (that's why there are only 3 chrono results per load, I'll test more soon), but case head expansion was minimal. I'm thinking this load could be pushed to 12.0gr or more, IF compression of the powder does not stop it. 11.4gr is VERY compressed, but I'm not getting bullet push-back, so I think I can go a bit further.


All loads used new Starline nickel brass, CCI 300 primers, Barnes 125gr TAC-XP bullets, and a COAL of 1.260". They were fired from my G29 with stock barrel, and 21lb Wolff spring. Temperature was around 90*, humidity about 70%, elevation 495ft. The chronograph is a Competition Electronics ProChrono Digital, all shots were fired from ~10ft.

Thanks for the Data 21Carrier!
 

Great data Carrier! Any powder preference - Unique, Power Pistol, 800-X so far with this loading? Cleaner burning, easier to meter etc.? Any thought to using a CCI-350 LPM primer?

-Jay (WMF)

Sorry, I just saw your post. So far, I would use 800-X, simply because it absolutely destroys all the others in velocity. However, the gap would likely be less in a longer barrel. As we all know, 800-X meters like crap, but is pretty clean. I think Longshot will be the ultimate winner, though. Mudrush has led me to believe that I can push further with it (mainly due to space concerns with the LONG Barnes bullets). The 11.4gr 800-X load shows light case expansion, so I know I can go further, but that load is HEAVILY compressed, so I'll likely run out of space before I get much more velocity. With Longshot, I should be able to get to 1500-1550fps out of my G29. As soon as I get more Barnes bullets, I'll work up some loads with Longshot.

Looking forward to the data 21Carrier. Longshot has become my favorite 10mm powder (and not just because I have 100lbs. of it. :rofl:) It seems to meter well and you can get really good velocities from it.

Well time flies...March 12th I posted the original post for this. I wanted to do a gelatin but did water jugs instead and tested two of the listed loads...Tested from the S&W 1006 5" barrel.

TAC-XP FB 140 grain pn# 40005 10mm/40S&W 0.400”

10.5 grain Blue Dot 1178 fps entered the 4th jug of water barely hanging on the entrance hole. Classic opened petals expanded to 0.7495". Primer slighly flattened.


12.6 grains of AA#9 (had to adjust powder shoving the bullet back out 1.270")(Totally compressed @ 12.6 gr.)
1181 fps, Primer was totally flattened to the edges. It penetrated 5" of sandy dirt and the bullet failed to open, partially folded in on itself.

I was not expecting the highest performance obtainable (but should be up there pretty good) but looking for the difference of what these same length, 140 grain bullets do as compared to the speeds from the 200 grain XTP's with similar full loadings. 10.5gr Blue Dot case 0.4275", 12.6gr AA#9 case 0.4280"

Here are the results of all five test shots...

10.7 grains of AA#7 @ 1112 fps three jugs inside 3rd jug of water. Petals opened as designed to 0.7495". Primer badly flattened. Case expanded to 0.4289”

8.2 grains of Long Shot @ 1247 fps entered the 4th Jug of water. Petals opened as designed. Classic opened petals expanded to 0.7915". Primer slightly flattened. Case expanded to 0.4275”

has anybody, other than Buffalo Bore, been able to safely move a 155grTAC-XP in the 1400fps range?

Unless someone has verified Buffalo Bore's claims, I only
see them as "claims" and not fact. And whoever verifies
it cannot ask BB for free ammo for testing. They have
to be anonymous buyers.

I have not personally tested the Barnes load. I have tested the 180 gr. They claim 1311 fps from a G20. I averaged 1335 fps (IIRC, it was summer temps). Others have reported chrony results that are consistent with BB claims too. I have no reason to doubt their claims.

Now I wonder if that is too fast, check out this fragmentation @1200fps:
http://www.brassfetcher.com/index_files/400CorBon.htm
(same bullet, different cartridge)
However Cor-Bon pushes the 155's to 1200, and they seem like the kinda folks that may know what they are doing :dunno:

Did you see the bullet fragments?
http://i1086.photobucket.com/albums/...assfetcher.jpg
This is what I was mentioning about over driving the HP type bullets, they open to their max expansion dia. then start to roll back on itself to a smaller dia. even shedding fragments, till it comes to rest.

So in therory, is it better to reach total expansion rather than over driving the projectile to the point it rolls back and/or sheds its petals?

This is the Barnes 140 grain at velocity as written by the picture...
