I kinda stumbled onto this load while doing some Lehigh bullet testing and based on how this bullet kills when shot from a 300 HAM'R I'm confident it will be VERY effective on deer and hogs.

125gr Lehigh Defense Controlled Chaos, 2.030" OAL, Lee factory crimp
17.6gr H110 (your powder lot may vary so start lower)
CCI450
New Starline case
2140fps 16.2" barrel
1.2"-1.5" accuracy from my two 16" barrels

The expanded bullets were shot into water from 50yds and the bases penetrated 20"

Blackout or HAM’R

pretty impressive for a blackout.

I’ve found that the Barnes Tac Tx 110 grain is very lethal out of the 300 BO.

Any chance you’ve tried the Sig HT 120gr, extremely similar ballistics but way cheaper.

No, but if they’re cheaper I’ll give them a try.

After reading the OP, and subsequently stumbling upon this while searching for Lehigh ammo:

"The development of this technology was the result of an animal control agency's request for a lead free bullet that would provide an extensive wound trauma with minimal pass through energy. Basically, the idea was to burst the bullet into numerous particles at a predetermined depth creating many wounds and a large temporary cavity at or near the central nervous system with proper shot placement. The agency had tried copper matrix frangible projectiles and found the penetration depth and particle size were less than what was required for proper terminal performance.The bullet is designed to penetrate to a specific depth and to fracture as the internal hydraulic pressure exceeds the hoop strength of the nose design. At the time of fracture, a massive energy spike is released as the particles break away and radiate outward from the initial trajectory path. This energy spike, and resulting temporary cavity, sends a shock wave through the animal's circulatory and nervous systems, immediately shutting down the functioning parts of these systems.

The Controlled Chaos technology differs from the Controlled Fracturing technology in that the fracturing particles are smaller, the penetration depth of the smaller particles is less, and the initial energy transfer is greater. These features make this an excellent choice for:

Nickel-plated brass casings, our nickel plating process provides several key benefits, not limited to but including; improved feeding in all actions of firearms enhanced corrosion resistance over traditional brass, improved cosmetics, and ease of cleanup during reloading. Nickel-plated casings will not tarnish like brass during storage or when in contact with foreign materials such as leather, moisture, and other metals.

As with all of xxxxxxxxx™ rounds, we utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.

While taking advantage of our state of the art testing equipment, this high-performance ammunition is field tested using popular, real firearms that our customers are most likely to own out in the real world with all the elements you would experience."

I may have to make my 11 year old .300 BO my full time Ranger ride carry rifle. Impressive and ideal for my application.

Edit, the copied quote was not Wilson Combat or Lehigh info, but that of a seller of ammo utilizing Lehigh bullets.

Blackout, it's no HAM'R in performance, but the best I've come up with for the Blackout. You can only do so much with the Blackouts limited case capacity.

The Sig 120 is similar to a Barnes TSX and is designed for 100% weight retention. The Controlled Chaos is designed to reliably shed 3 fairly large pedals and the base to penetrate deeply. What you get is a massive wound channel and a blunt wadcutter penetrating deeply.

John Nosler back when he did the first partitions said the ideal hunting bullet would expand secondary projectiles separating from the bullet spreading out causing a larger wound channel yet hold together for deep penetration. Same principal still works today.

I think of most LF expanding bullets like Barnes are similar in on game performance to handgun bullets with a large meplat. They expand but become a wide flatter surface with deep penetration causing a wider but not as spread out wound channel as secondary projectiles from bullets that shed weight in that form.

Just my observation from using lots of different bullets, and thinking with my engineering brain.

Lehigh makes some great stuff, and that performance shown in the original post is ideal. When we designed and built our bullet for the Blackout, the 161gr Haymaker, we wanted to maximize everything we could about the Blackout's capability as it relates to hunting situations from short to mid range. Here are some bullet points (pun intended) on its key criteria:
1. Maximize "out of case" bullet length for better powder availability in the small Blackout case
2. Incorporate Apex Outdoors' patent pending geometry for reduced bore fouling and friction with increased accuracy
3. Incorporate a petal shedding design with petals roughly the size of Lehigh's heavyweight bullets with a wadcutter or semi-wadcutter base of sufficient size and stability for ample penetration on game up to the size of moose (absolutely perfect for all deer and pig hunting out to 300 yards)
4. Have a terminal performance velocity band that dips into the subsonic range, but is capable up to 2400 fps, beyond maximum Blackout muzzle velocities (roughly low 1900 fps with a 16" barrel)
5. Hit harder than anything else in the Blackout out to any and all practical ranges

Loaded in the Blackout, a great powder we've found is Ramshot Enforcer. A good starting load is around 15.0gr. Work up in small increments. In a 16" barrel, a fair bit of compression will be met with a top end somewhere at or just above 1900 fps. This will be case fill based more so than pressure, which is a great thing if we're discussing ARs.

The pictures below were shot into 10% gel, backed by a second block of 20% gel, with an impact velocity of 1050 fps. The base penetrated into the 20% block for a total of 17". The results at an impact of 2150 fps, over double the lower impact velocity, were identical, but more severe. We didn't recover any of the petals because they all burst out the sides of the gel. They are available now, and in fact we have someone hunting moose with them in a Contender pistol as we speak.

A 125 at 2140? That’s cute.

That picture of petals with the base intact ain't cute. By that logic, the 45ACP is cute.

Yep.

I'm using a 145gr cast FP GC'd @ 2k fps from 18" BO carbine or 10" pistol, slower. Also got some 150 BO GDs loaded but alas, no pigs yet. Hunting different area, E Texas. Seeing lots of deer on the cams. For long shots I'll use the 308W and jacketed. Did get a tx heart shot on one with 40SW, ran about 100 yds. Broken front leg and not much jaw left. Kid doesn't want hogs there but then I got no targets!! Did toss some oats on the ground around the feeder, she said gone next day. Waiting to see the cam pics.

The bullets did exactly what they were designed to do and all of the Controlled Chaos bullets kill hogs DRT with any reasonably well placed shot. They were not designed to be "cute"

How about some pics of the CC's after being fired into animals or test medium?

Ordered a Box of the Haymaker 161's.



Got 'em next day! Wow!

Gonna' load some up in the 300 B/O and shoot over a chrony' to see if i can find a sub-sonic load that the rifle likes.

Any suggestions as to powder & density would definitely be appreciated.

Best,

GWB

We used 12.2gr of CFE BLK out of a 16.25” bolt action to get 1100 fps. That was mostly developed to test terminal performance at the lower levels. No real optimization done with that for accuracy, but wanted to give you a point of reference. CFE BLK is a bit slow to maximize velocities on the high end, so it works out quite well with case fill on the lower end.

My experience is CFE BLK is much too slow for top super sonic performance out of the 300 Blackout. H-110 lives closer to that achievement. BLK is about perfect for the 300 Ham'r and probably about perfect (I don't load subs) for subsonic heavies in the 300 Blackout.

I've not done a lot of load testing with the BlackOut.

In fact I got lazy and did not chrono this load.







I'm not near as anal about sub inch groups as I wuz a while back.

These days, Minute of Hoglet is good enough!

ya!

That’s absolutely correct on the high velocity. I believe he was looking for a subsonic load. However, if going for a high velocity load, we had good luck with the same gun and Ramshot Enforcer. Start at about 15.2gr and work up slowly. We topped out at 16.2gr mostly due to case fill. Velocity was low 1900s with good accuracy.

Heard the comment about removing the tip off SSTs. Due to mag length or other need?

These are not boat tailed, correct? Any tips for getting these 110 gr non-boat tailed bullets to fit easily into the 300 BO brass?

The Barnes 110gn Tac-TX in 300 Blackout is an awesome load. This boar took one in the side neck that exited in the bottom neck.
