Lehigh Defense Maximum Expansion 194gr, COAL 2.180 or 2.220?

Post by JakFrost273 »

What COAL?

2.180" - As manufacturer recommend in the Load Data PDF for 01308194LP and used by LD for their Ammo load lengths?
2.220" - As seen on this forum after carpsinperg2 called the manufacturer?

I also asked the guy about h110 and starting them around 10.3-10.5 grains and he thought that would be about right so I will try there info and see what she tapes out at. I will post result when done but it will be a few weeks before I can test ammo as I am in the middle of hay.
To answer my own question, I'm planning to make some bullets and measure the length at which the bullet ogive hits 0.250" inches to clear the magazine rib. Just curious to see if anyone did this already and knows the distances?

PS: Hello to everyone on this forum. I've been using it as research and I'll be posting back some load data after I find some free time after this weekend's hog hunt. I'll be using 300 BLK with LD ME 194gr .308 at 2.217" COAL with A1680 11.4gr @ 1,049FPS with LFCD Medium and CCI #41 in an LMT 10.5" Pistol Gas barrel with Surefire SOCOM762-RC-FDE suppressor verified with MagnetoSpeed V2 chrono and QuickLoad with 0.6545ba powder burn rate factor at 27,037psi and case H2O capacity 24.30gr.

I used 2.220 and 10.8gr of 1680 and had no problems feeding or firing.

High there and welcome!

If this is your first attempt at subsonic hunting be sure you read the following thread and EVERY link referenced in it (be sure to check out mine) to get you fully prepared for the subsonic hunt viewtopic.php?f=145&t=87186

Subsonic hunting is better thought of as pistol hunting or long range bow hunting. To think of it as traditional rifle hunting will get you in trouble and disappoint you. There is way more complexity to overcome when sub hunting which makes it more fun and challenging once you understand that fact. Get good with point of impact with your subs at various distances (a marked reticle helps with this), know that a range finder is basically a must, and get as much trigger time practicing shots at various distances (50yds, 65yds, 80yds, 90yds, 100yds). There is no substitute for this kind of practice!

Also with the 194 ME avoid the shoulder blade of the hog. The bullet will start expanding as advertised but will not be able to penetrate the shoulder blade if it has started expanding. I know this from personal experience this past hunting season. If you earhole a hog or avoid shoulder blade/mid-shoulder shots you will have no problem with the bullet.

Finally you will probably need to shoot and shoot and shoot to get the speeds you want. I would recommend that you try loading with a cheaper 200-208gr bullet until you find the speeds you are looking for. THEN load the 194 ME make a small loading ladder using the same amount of bullet in case as your test bullet and use a ladder of powder charges right around the charge you used for your test bullet. This approach will help you get the speeds you are looking for with the ME while helping avoid shooting a ton of super expensive bullets. It has worked wonders for me.

Get prepped and enjoy the hunt, it will be a new thrilling challenge! :)

Got it. Already read your thread twice before, know to avoid shoulder shots. Already have a verified chrono loads for this bullet in my barrel and I have QuickTarget bullet drop graphs for this specific load already made also for my gun with 72mm Center-Of-Sight-Over-Bore height shown below as a table. Graph is prettier.

Now you just need to drop a hog and post about it in the hunting section. I wish you luck and am looking forward to the pictures including bullet inflicted trauma and the recovered bullet itself :)

I am a backup shooter on this hunt and volunteered to opt-out of shooting if the two primaries who are using supersonic 7.62x54R with 150gr hot-hunting loads bag hogs. Fridge space and money are a limit for this "staged" hunt/weekend in the woods.

Confirmed, those 2.220" rounds worked just fine and I bagged a 110lb hog within the first 10-minutes after the start of the "staged hunt".

A not-so-bright or too-much-of-a-brave hog walked up and down the fence line right up to 17-yards away from me a few minutes later in broad daylight as I was sitting bored watching some goats that came to eat all the corn on the ground. Too quick and a little too-good too be true so early, I let the guy walk all the way up and down the fence line before I decided to take him since he fit the criteria of what we wanted to bag for that day for tasty meat and be done with this whole "staged hunt".

I shot him in the lower rear lung area right in front of the liver about 2-inches above and 4-to the rear of his elbow. The bullet entered the rib cage, broke a rib and turned inside and proceeded through the lungs and up and out into his throat and neck area breaking his spine and causing paralysis and massive bleed-out, a 2-foot puddle of thick dark blood and brightly colored bubbling blood from the lungs. He twitched a few times and tried to move his head but his body was paralyzed and he died within 5-seconds. I saw him struggling after the first shot that put him down so I tried to euthanize him with a head-shot but missed due to being too quick to do it but he expired almost immediately anyway so it was unnecessary since there was no struggle.

No pictures of this since I did like my friends who had no cell signal and we all left our phones in the hunting lodge and relied on radios for communications instead. After we got the hogs back my friend got his phone and used it to take a video of the skinning process but his phone ran out of memory and recorded some footage but lost most of it. Anyway, nothing out-of-the-ordinary looking from the hog hit, ordinarily bloody internal organ damage, and pool of blood. Google some Images and they'll all look the same.

However, my bullets went supersonic on me with that tell-tale 2-by-4 slap even though they were only loaded with what should be 11.4gr of Accurate 1680 that was chronoed the day before at the range at 1,006 FPS average with 22 SD and 75 ES with min 970 FPS and max 1045 FPS at my range that was at ~60F at ASL 125ft and we were hunting at ~50F at 320ft ASL so no drastic elevation or temperature differences and similar weather. The only difference was that it was raining when I chronoed my loads on Saturday and next next day on Sunday it rained a few hours earlier but then stopped.

The only things I could think of that could have caused this is the low-pressure difference between the day it was raining and the next day while hunting, or there's a chance that I might have loaded some of these with 11.7gr since I was loading some SMK 220gr the same day. I'll pull the remaining 10-rounds to weight the powder in a little while.
