Reload Chrony Report for Barnes 155 & Nosler 200

[Caneman]

All velocities with a Glock 20C using a Storm Lake 5.3" 2 Port barrel


powder  /  charge (gr)  /  avg velocity (fps)  /  standard deviation (fps)  /  case head expansion (in)  /  notes


Parabellum Research  200gr Hornady XTP  (factory round)
powder???  /  ?  /  1261  /  11  /  0.4280  /  4 rounds tested, 5.3 bbl, Storm Lake 2 Port
powder???  /  ?  /  1190  /  17  /  0.4335  /  4.6 factory compensated bbl with 2 ports

Notes:  this gave me baseline "full loads" for velocity and casehead expansion... notice how the fully supported replacement barrel minimized case head expansion.


Nosler 200gr JHP  (reloads)
800X  /  8.2  /  1169  /  13  /  0.4268
AA #9  /  13.3  /  1184  /  6  /  0.4262
AA #9  /  13.5  /  1205  /  3  /  0.4268
Blue Dot  /  9.8  /  1197  /  nd  /  0.4263  /  chrony acted up so i was only able to clock 1 round, i believe the avg would have been higher with all 3
Blue Dot  /  9.9  /  1251  /  9  /  0.4273
Longshot  /  8.0  /  1172  /  11  /  0.4263
Longshot  /  8.3  /  1212  /  2  /  0.4267
N105  /  8.4  /  994  /  23  /  0.4255

Notes:  Both AA #9 and Longshot were the clear winners for me with this round, with the Longshot giving outstanding consistency.  The N105 was a big disappointment as I was just using book loads from VV but there is a poster on the Glocktalk 10mm board that loads up to 12 grains with N105, however I am not that brave!  I think N105 is not worth testing any further, but it is a great powder for my 0.44 Mag reloads...


Buffalo Bore Barnes 155gr TAC-XP  (factory round)
powder ?  /  11.0  /  1286  /  12  /  0.4262

Notes:  not quite the 1500 fps advertised but still pretty impressive as far as I am concerned... the shell kicked out a few feet after being ejected and the load produced a very easy and manageable recoil... wish I knew the powder they used as it is clearly outstanding, I pulled out a bulled and measured 11 grains of a powder that wasn't quite as fine as AA #9 and a dull dark grey, it was so heavily compressed that the powder came out in a plug!


Barnes 155gr TAC-XP  (reloads)
800X  /  8.1  /  1161  /  3  /  0.4262
800X  /  8.3  /  1231  /  14  /  0.4270
Longshot  /  8.2  /  1260  /  6  /  0.4273
Power Pistol  /  7.6  /  1124  /  40  /  0.4262
Unique  /  7.2  /  1193  /  3  /  0.4263
Unique  /  7.3  /  1276  /  6  /  0.4277

Notes:  Longshot was the clear winner for me here producing a mild recoil like the Buffalo Bore factory round...  I had to develop this load because where I hunt I am required by law to shoot lead free rounds only.  I will probably dial back the Longshot a few tenths and see where that takes me.  Unique did extremely well, but Barnes lists a max charge of 6.4gr so as you can see I am over book on this one and it made me a little nervous (I went this high because I was able to find a Hornady book load for their 200gr XTP using a 7.4gr max so I thought it would be OK and it was - you can develop a load for the 155gr Barnes using load data from 200gr copper jacket lead core bullet because they both have similar bearing surfaces.  The Barnes 155 grain is a very long bullet for its mass, this is why people get confused on why an all copper 155gr bullet for the 10mm tops out around 1200fps and they think it should be going more like 1400, the bearing surface is just too large).  Power Pistol was a big disappointment, as I load this with the Barnes 185gr for my 45 ACP and it does very well.


Precision Delta 180gr FMJ (inexpensive practice round, reloads)
Blue Dot  /  10.4  /  1205  /  31  /  0.4262
800X  /  9.6  /  1320  /  24  /  0.4260
Longshot  /  9.2  /  1317  /  9  /  0.4272

Notes:  Longshot the clear winner for me here, glad I bought 4 lbs of it!


All primers were Winchester LP and OAL was 1.255.  Averages and standard deviations were based on 3 rounds, unless noted.  There were no "smileys" or other deformations on any cases or blown primers, and all cases were once fired Starline with a starting casehead OD of 0.420.  22 lb after-market spring was used.  Based on the casehead expansion from the full load PR factory rounds all of these loads could probably be increased some, but overall I am very satisfied with the results.  I can see now why many call Longshot the 10mm powder.


edit:  i forgot to add that i made some snakeshot:

-4 grains of Power Pistol
-cardboard wad cut from a .40SW case (thin cardboard like from a soda 12 pack package)
-36 grains of #7-1/2 non toxic shot (again, I have to use non lead projectiles from any firearm when hunting due to the wacko libtards here in CA)
-cardboard wad
-fill the rest of the case with hot glue

This results in a hot glue slug being fired (about 3/16" thick) and a fairly decent pattern.  There are approximately 30 bbs in 36 grains for this particular brand of shot i used, and 23 hit a water filled milk jug at 10 feet  (the slug and bbs penetrated)... good enough to knock down a rattler...  at 30' i had 9 bbs hit my 6"x6" target.

Interesting information. How do you like the PBR's? I think it equates with what I see.

[Caneman]

those PBR's are a lot of fun to shoot... i only bought one box but should have got a few more while is was at it

[Intercooler]

Stay tuned. I am sure Anthony will let me know when he gets his next drum of brass. I would like to talk him into some kind of signature HP for his ammo if something shows good results.

CaneMan, Thanks for the report, good info!

Great work Caneman!  Thanks for sharing it.  Nice information for others of us to compare to.

I especially got a kick out of you saying;  "it was so heavily compressed that the powder came out in a plug!"

I also live/hunt in the no-lead buzzard zone, and have developed a lot of loads with the Barnes bullets.  I shoot the 155's at 1500 FPS from a 5.2" LWD barrel.  1200-ish isn't near satisfactory for hunting, and 1500 barely makes it.  You can't get there with Longshot (too slow), or Unique (too fast).  The bullets are long, but the bearing surface is misleading.  They are tapered quite a bit , nose (.398") and base (.392"), with only a bore-diameter surface in about the middle (.400).  The solid copper construction is also less maleable than a thin jacket around a soft lead core.  This may make a difference with the Glock barrel, but rifling on recovered bullets (fired from the LWD barrel) seem about the same as conventional bullets.

I've seen evidence collected over time that showed lead wasn't a culprit in killing off any birds of prey.  Too bad such a law exists.

[Caneman]

^^^ supposedly they would have to feed the buzzards with several servings of lead bullets per day over the course of many years for there to be any harmful damage... but the limousine liberals feel real good about themselves now that we not shooting bambi or thumper with lead bullets anymore...

what is the goldie locks powder for the 155gr Barnes in the 10mm?  what type of case head expansion do you get at 1500 fps?

I hate to think;  What next?

You get 1500fps from a 10mm load consisting of a 155 grain Barnes all copper bullet from 5.2" of barrel?!?

I'm quite sure that isn't possible, not even from a carbine length barrel with that bullet.

Or is the 155 @ 1500 a Gold Dot or other lead core which is possible?
