King Ranch, 24 3/4" Waterbuck, 80yd shot, 300 HAM'R 150gr SST, ran 20yds with a shoulder shot.

No he wasn't in a pen enclosure, the fence in the background is just a cattle cross fence!!!

You can find the 130 gr. Hot Core at Caliber Armory. $1.50 a round.

if I'm using an 11.3 barrel, and will experience decreased velocities due to that, would I do better hunting with with something a little more fragile like a varmint bullet than a tough bullet? That principle seemed to apply to the blackout, and I figure a 16" blackout and an 11 inch ham'r are fairly similar.

I ask because I'm struggling to find the 130grn hot core in stock, and I have found some 125 tnt's at a good price. I mostly hunt smallish pigs (rarely see anything over 200lbs) and the occasional coyote/deer/dog/turtle.

I've shot several dozen pigs w HAM'R loaded with 125gr TNT including one above 300#. It works fine for standing shots with some complete messy pass throughs on pigs under 200#. When they're running & the hits aren't always perfect I feel the bullet shows some weakness on the bigger pigs. I put 6 in my big boy before he laid there and let me deal the coup de gras.
IMO, the TNT are fine. My 135gr FTX effect wasn't notably better on pigs as they were still sucking up multiple shots that were less than perfect placement. Same w my 135gr bonded and 130gr HHC other than these punched through and exited almost every time.

I've also had some luck with 110gr VMAX in HAM'R producing results I'd never have expected on pigs. If you are considering TNT you may want to look at these as well. They're punching through pigs but they are not fur friendly on coyotes. :-O
I loaded some in .308 just to see if they'd disintegrate on the impact w hogs. I took a 200# at 200yds with the Amax doing 3K+ fps at the muzzle from a 16" bolt gun. He went down like a sack of bricks after an intentional shoulder test hit. He did manage to gain his feet within the first 30 seconds but only made it 7yds before tipping over for good.

I didn't have time to attempt recovering the bullet but it did it's job well enough to tell me 2600-3000fps it's still holding together & penetrating well enough to kill hogs reliably.

All of my experience with these bullets have been in 300BO so perhaps the additional 300fps makes a critical difference. From 300BO I found the 125gr TNT to be a great plinking round and small game. However, it doesn't get the expansion that other bullets are designed to do. It will do in a pinch, and a head shot is a head shot, but I would select a different bullet for hunting. Also, I am on the fence on using 110gr VMax. Again in 300BO, a friend shot a 150# pig in the shoulder....nice impact crater that didn't do much internal organ damage....pig would have wondered off and eventually died from infection/shoulder damage. A single shard of metal the size of steel pin punctured the heart. We found the pig 50 yards away.

I want expansion and energy dump. I enjoyed the effectiveness of the 110gr Barnes TAC-TX in 300BO ... I am hoping the 110gr Barnes TSX has same level of performance in 300HAMR.

Single best bullet for hunting whitetail deer with the 300 ham’r. And go!!!!

I don't think there is a "single best", all of the following work well. Right now I'd pick the one you can get that shoots good in your barrel.

Lehigh Defense 95gr CC
Lehigh Defense 110gr CC
Speer 130gr HAM'R HOT-CORE
Hornady 135gr FTX
Speer 135gr HAM'R BONDED
Sierra 135gr HP
Hornady 150gr SST

DJones and myself have killed hundreds thousands of hogs with the 125 TNT.

fixed it for ya
