Badlands Precision Bullets thread - From BC to terminal ballistics

Well, I got updates, but not of my own ha ha. Ended up having some other obligations that had to be taken care of.

However, my cousin and his wife were able to take all four of their doe pronghorn, all with the 140 Badlands SBDII. My cousin's two were taken with the bullet going 3240 from a 25" .270 Sherman (.270 based), and my cousin's wife used her 19" .270 Sherman, with the same bullet running 3060.

Goats 1 and 2 were simultaneously hit, they both took their shot on the count of 3, and dropped both Goats in their tracks, at 440 yards. Both were broadside, one hit was center body center lung, one hit was center body but back of lungs, both goats bang-flopped, and died quickly. Terminal performance was identical on both, bullet sized entry, golf ball sized exit, as is seemingly typical, with a couple surrounding secondary exits out of the rib cage, we're estimating from petals. Impact velocities were 2730, and 2560 fps.

Goat 3 was 250 yards, high shoulder/bottom of spine hit. 45° quartering to, entry was top of scapula, exit was center ribs, about baseball size, a few other small surrounding exit channels, with the slower of the two Sherman's. Bang-flop. Impact velocity was 2773 fps.

Goat 4 was 660 yards, slight quarter to. Bullet entered front of shoulder, just barely in front of the scapula/humorous bones, exited center shoulder on the off side, hitting bone. This goat rared up on it's back legs as it took off for a 9 second death sprint, and covered roughly 100 yards in a semi-circle, before it piled up and kicked for a few more seconds. Exit was golf ball size, again, with a few other surrounding rib cage exits. Impact velocity was 2490 fps.

Unfortunately, I have received no pics on these ones, only seen the videos and heard the reports from my cousin. If I get photos, I will add them. But figured it was still worth an update. I didn't ask him about meat damage yet, I believe they were finish processing them today, so I will find out. I know he recovered an aluminum tip from the impact side shoulder of one of the goats, I suppose I can add that pic so this post isn't completely dry ha ha.....

Overall, these 140 SBDII's seem to really be kicking butt. We now have 6 pronghorn, 1 mule deer and 1 elk taken with these bullets from I think 250 out to 660 yards, and they are working fantastic thus far, no recovered bullets, and great terminal performance.

I do think 2490 is about the lowest impact velocity we have so far though, I would like to see how these perform in the 1800-1900 fps range, however that would be 1150+ yards for the slow one, and 1300+ yards for the fast one, heck these are still traveling over 2000 fps at 1000 yards from the 19" barreled gun, so I can honestly say I'm pretty dang confident that these bullets will perform at any range we are likely to use them at......

Throw these in something like a 27 nosler, and the performance would be unreal. Not only would it kill like a champ and likely always give you exits, even at velocity extremes, it would also be a rail gun. On top of that, the bullet has the bc that it will perform in wind better than any other .277 bullet out there, including the 170 Berger. This may be the bullet I build my son's rifle around!

That's freaking awesome, Congrats to all, Bullet performance sounds absolutely awesome as well

I'm looking at building a rifle around that 160gr 7mm depending on how the hunt goes this fall with another bullet of theirs. The BC on that 7mm is really high and makes it almost impossible not to have 2000+fps hits way way out there. It is so incredibly long, and I want a short action, I'm not coming up with much that doesn't eat the powder of about any case.

If you run a 700 SA you can get 3.235" with the Wyatt's box or just go with a mid length action.

Ya, I'm aware. I'd like to avoid both of those due to weight.
 
After switching from a 10-shot ladder approach to an OCW testing approach, I was able to find a load in my 25-06 that is now shooting consistently under MOA. All groups below are at 408 yards. From top to bottom, cold bore group was 0.31MOA, second group was 0.75MOA, and bottom group is my 300 PRC that shot 0.42MOA.

I am pushing this 22" 25-06 pretty hard and getting 3570fps in the summer heat here in Missouri with 56.5gr of IMR-4831 and the .257 BD2 95gr.

I'm heading out to Wyoming on an antelope hunt in late September and hope to bring home a decent buck.

Excellent summary!
 
Well, guiding season is done for me, so it's back to getting this 300 PRC dialed in before my trip next month.

Here is some recent load data for the 300 PRC with the 195 grain BD2. I haven't hit any pressure signs and I'm getting pretty close to the speeds I'd like to see (2960-3000). Hopefully I have it shooting sub MOA at 100 by this next iteration of development so I can get a load ready to take out to the big range and see how it performs. If I don't like what I see I will just take my 338 Norma with me on the trip.
