??? Don't know? No one in Australia will eat them? My First trip I was amazed, Cape Buffalo in Africa is one of the tastiest treats there is on the planet, figured Asiatic buffalo would be the same. Australians and even the Aborigines absolutely will not eat them. They turn it into dog food at best.

The past several years, as I understand now, they are herding them up and putting them on ships to China. As we might guess, especially considering todays circumstances, the Chinese will eat anything I suppose. Asiatic buffalo would be a hell of a treat in place of some of the things they eat I reckon.

When I was going to Australia between 2009-2012, we were doing selective culling operations, so I was able to get a good tally going and do some incredible test work with the bullets and cartridges I was working with.

What was your go to on water buffalo? I predict my lifetime will never allow for a real trip, but I can still hope the zoo will have an escapee one day and I can put my .458 Lott to real work. Ha!

Most were taken with 500 MDM and 458 B&M, I did take some with 475 B&M, 416 B&M, even tried 9.3 B&M. My boys used 50 B&M Super Short and 475 Super Short on one trip, I had friends that used 50 B&M and another with 500 NE.
After the first trip, our friend and PH got himself a 500 MDM in which he used, and still uses to back up clients with.

The only H-110 tested was for a friend of mine with 100 FB Raptors.

100 FB Raptor 19.3/H-110 53200 PSI 16" 2465 fps

We consider 55000 PSI Max Safe Pressure for sustained use in various Semi Rifles/Handguns and for 300 BLK Cartridge overall.

Michael, what COAL do you suggest for the 300BLK 100g Raptor with H110?

Sorry, I have been out of town for a couple of weeks............ Basically if it fits proper in a magazine, good to go....... About midway in the middle band............

I loaded up a handful keeping the dies where I had them for Hornady 125g rounds , the Raptor loads have a 2.19" COAL, 19.g of H-110, it shot a 1/2" group at 100yrds!
Now to fill the freezer.

Sounds Plenty good to me................... I use 20.3/WW 296 for the 100 FB Raptors........... very consistent..........................

Keep us posted...................
 
Not trying to thread jack but anyone loading subs? Looking at 220gr and aa1680 loads.

A few weeks ago a good friend of mine in Oklahoma needed my recipe for the 300 BLK and 100 FB Raptors....... I sent it to him, and a couple of days later he sent a report of 1/2 inch groups at 100 yards, same as @Get Off My Lawn .

Then over the weekend when we were returning from South Africa he sent a couple of photos of his grandson slamming a deer with it.......... and just last night another one of the kid slamming a pig too....... Reports are "Terminal Performance is Extreme", all DRT on the spot..................Can't get much better than that.............

I've loaded Hornady Match 225's over 1680 from 10.0 to 10.5 grains, all cycled in a 9" barreled AR15 w/suppressor. In my gun the 10.3 load delivered speeds around 975 FPS.

I load 220 gr nosler custom comps over 8.5 grs of H110, coal 2.255. normally get blems from shootersproshop. I tried a1680 for these but they sounded so much louder even though they were still subsonic.

Is 1680 a preferred 300BLK sub powder choice?
Click to expand...
It is pretty much the go to for cycling an AR, but not the quietest choice because of that. I use 11.8gr for a 190 Sub X which is still subsonic but just barely. I think I was using 10 for 208 AMAX.

I have done the AMAX with Unique and they are stupid quiet, Hollywood quiet, but won't cycle a bolt.

20gr of H110 is my go to with a 110 Vmax. They're hot.

How much unique were you running and was this with or without suppressor?

Based on my notes, 6.4 was where I stopped, but a word of caution, there is no published load data for Unique that I've ever found and I started with 45ACP data as a starting point.

And yes, with can. I'd love to find a Ruger American in 300, it would be a hoot in something like that.

Purely a learning question, but why is CFE223 never used in 300BLK? It's fantastic in 556 and 308, so why wouldn't it have a good place in the 300BLK world?
 
Burn rate. CFE223 burns too slow as compared to preferred powders like H110/1680. That’s not to say you couldn’t work up something that would work (especially on longer barrels /not pistols) but you may have to work the load up yourself.

Seems like CFE223 in a 16" barrel with a 110gr bullet would be more ideal than H110. I'd love to see some solid comparisons.

Not just burn rate, but case capacity too. CFE223 loads that I have seen have been fairly high as far as charge weight with 5.56 velocities. Cut that down with a shorter case, larger bullet, etc, I think you'll quickly run into issues.

CFE223 is way, WAY down the burn rate chart from H110/W296 too. Part of the magic of 300 is the fast magnum pistol powders to get velocity, and remember, it was developed around a pistol length gas system and an 8 inch barrel.

CFE BLK is out there and available from what I have seen recently too.
 
I'm going to add my load recipes from my 19" 1 in 8" twist bolt gun as this appears to be the best .300 BLK reference thread on the forum:

Supersonic .300 BLK Loads for 19" bolt action rifle. None of these loads have been tested in an AR pattern/semi-auto rifle. These are near or MAX loads!!

Case: Starline
Primer: WSR
Powder: H110
Chrono: Magneto Speed V3

100gr Cutting Edge Raptor FB = 19.85gr OAL=2.244" FPS=2500
110gr VMax or Varmageddon = 20.60gr OAL=2.0535" FPS=2550
130gr Speer Varmint = 19.18gr OAL=1.976" FPS=2315
110gr Barnes TAC-TX = 19.76gr OAL=2.2380" FPS=2475
 
Going through my bullet inventory of .30 cal projectiles I apparently at some point doubled the amount of Hornady 135gr FTX bullets I originally ordered for use in my 300 HAM'R. It's a bit of an odd duck bullet for the .300BLK in that it is the heaviest supersonic offered in a commercial load. Ideally, I believe this would benefit most from a 16" barrel (or longer) in order to achieve maximum published velocity of 2085fps. In the 300 HAM'R I'm getting 2345fps from a 16" barrel. I did work up a .308Win load for my 18" Savage Hog Hunter that is clocking in at 2830fps!! In both the HAM'R and .308 Win I've found the bullet to be highly accurate and would expect similar accuracy in the .300BLK. I'd estimate with the 19" barrel on my 300BLK I may be able to get velocity up to ~2250fps.


Does anybody have any experience loading or shooting these bullets in .300Blk or .308Win? @Michael458 by chance have you ever tested these? Mostly just curious what else I may be able to do with all these extra bullets, thanks.

No, just not something I would be inclined to do. I did however make a mistake in an order, ended up with some 125 Hornady bullets. I was able to use 17/LilGun for 2141 fps in 16 inch 300 BLK but at a cost of 58000 PSI. I also tried WW 296 but it was a little fast, reached higher pressures at less velocity.........

Sometime later I tried the 125s in 308 and had a very good load with them, and they matched POI at 50 yards with the 100 Raptor standard load, it was 46/IMR 8208 for 3082 fps in the 26 inch test gun at 48000 PSI. Same load in 18 inch guns ran 2928 fps.

And of course I also gave them a run in 7.62X40 with 25/CFE BLK for 2346 fps in 18 inch guns at a low of 43500 PSI..... as I recall I could not get more CFE BLK in the case.... I did a test load with LilGun and increased velocity to 2450 fps at average of 55000 PSI..... However the extreme spreads in pressure was way over what I would accept at 5200 PSI, without a lot more testing I would not accept those kind of numbers, and to be honest, I didn't care enough about having a load in 7.62X40 with a 125 to bother with it. Absolutely knowing that the heavier bullet could not come close to the Terminal effects of the 100 Raptor, there was just no point in wasting more time with it.........
 
Thanks for the response @Michael458 . I was hopeful that the 135gr FTX had been tested at some point since you already showed data on the Hornady 110gr Z-Max/Vmax and Soft Points in .300 BLK.

I know it won't be as devastating trauma wise as the CEB Raptor, but accuracy of this bullet in both the .300 HAM'R and .308 Win ( 1 in 15" & 1 in 10" respectively) indicates a potential worth exploring further.

I'll start with H110 and maybe try some Lil' Gun. It will likely be until late January before I have anything to report.

Just a quick look at the Hornady data and it appears it is almost exactly matching my data here, mine was 125 gr and 16 inch barrel..... 17/LilGun for 2141 fps... .But I am looking at two tests done with the 17/LilGun same day, I imagine I did not like the first test, and did a re-test, and here is why....... Pressures on the first test were Hi 62400 PSI--Low 51100 PSI--ES 11300 PSI....... Average 56800 PSI 2112 fps.......... That ES is way way way out of spec. The second test as follows; Hi 66000 PSI---Low 51000 PSI---ES 15000 PSI....... Average 58400 PSI for 2141 fps........ That is two tests back to back that were just not acceptable in any manner.......Now, that is not to say the 135s don't do some better and to take note of this, ES in Velocity is not always an indicator...... Velocity was taken with LabRadar at the time...... The first test the velocity only had a 4 fps ES! The Second test velocity had a 73 fps ES.

That is not to say you would have the same with the 135s...... Bullets do make a difference in the way pressures work. Consistency, thickness of jacket and all sorts of things we cannot even imagine or see....... I might have had a bad batch of 125s.... ??? They were Hornady however..... LOL......

What is ES?
Click to expand...
Extreme spread between Hi and Lo............ With pressure readings it is common to have 2000 PSI difference......... I really start liking a load that is down below 1000 PSI....... but have no real issues with 2000 PSI or so.......this is with rifle cartridges....... Handgun cartridges can be all over the place and I will accept a little higher ES with those, but not a lot more........
