Badlands Precision Bullets thread - From BC to terminal ballistics

[BuckeyeRifleman]

Killed my bull with a 7 SAUM pushing a 150 gr BDII going 2950 at the muzzle at 250 yards this week. Twist is 1/8. Bullet performance seemed admirable, but unfortunately only got one lung. I'm still not sure how, either there was a slight quarter towards us that neither my partner or I picked up on, or the bullet veered off course on impact. There was complete penetration with a few petals left at the exit wound.

As you can see the entrance was true, nearly perfect, but the exit was too far to the rear and appeared to exit the stomach.



The shot was at last light and he slipped back into the timber. I did fire a second shot as he turned that hit him above the hindquarter. We went to look about 30 minutes later and he was about 75 yards up the hill but had his head up looking at us. (What a horrible feeling) We had no shot and it was after legal light at that point.

We gave him the night and he was dead and in full rigor in the morning, he must've expired right after that.

I don't blame the bullet, I very well could've just not picked up on the slight quarter towards at last light, and between that and not compensating for the wind at that distance was just aft enough to not get both lungs. But bullets do curve and do weird things when they impact flesh occasionally. I wish I would've gotten my phone skope up for the shot, but it was a bit of a rodeo when he appeared (I was about 30 yards from my pack/rifle when he walked out like a complete f&cking rookie.) Like I said buddy felt he was full broadside as well, but sometimes a slight quarter isn't obvious.

Overall pleased with them, I will continue to use them as they shoot really well in my rifle.

Been working through this thread for the past few days with lots of interest after discovering the 100gr 6mm SBD2 with a wild .307 BC!
I saw they require a 7" twist on the website and checked Berger's stability which showed "marginal." I also saw where y'all discussed the monos get rated a little differently than lead bullets for this. I'm still a little concerned about the stability, but would really love to use this bullet in my new rifle if possible.
7" twist is the fastest X-caliber offers on 6mm from what I can tell. This rifle will be chambered in a wildcat that should mirror the performance of a 6mm PRC or 6-284.
I live at 2,000' and like to shoot at my house, but hunt higher up in the 5,000+ range.
Anybody shooting these little 100 grainers?
How do they do in a 7" twist?
What elevation?
Velocity?
Sorry for the novel.

You will have no issues. With just the vel or the elevation your stability will be well above 1.5SG. Combined no issues.

Playing with JBM Modified Point Mass Trajectory I tweaked an example bbullet to get a 1.5 sg @ 2700 fps 29.92 Hg ASL. I then changed to 24.63Hg for 5k Alt and 3200 fps = SG 1.94

I know the 6-284 can send the 105 hybrid @ 3200+ 26" with retumbo. IIRC years ago someone had a retumbo load from a 30" that went 3350? That was before rl26 n570

Nice thing is you have a high bc bullet that you do not have to worry about spinning it out of its jacket, and having it disintegrate down range, as its a mono.

That is going to be a lazer and a sick combo 100gr 3300fps g7 307 it's still moving along at 1850@1k that's ASL @ 5000ft it would be 2075 fps@1k

I shoot a 101 mono made by a competitor out of a 7twist and it performs flawless. Also recommended twist rate of 7. You will have NO issues here. I live and shoot at 2200 elevation and hunt up to 6000 with this rifle and it performs flawlessly with that mono.

Thanks
This will be from a shorter 23" barrel to keep it a little handier for the mountain/timber hunting I like to do.
From what I can tell, if BC is accurate and the bullet will stabilize, I'd be supersonic WAY past any distance I've ever even considered shooting!
Hoping to get 3300+ fps

That 101gr is the whole reason I even started considering a fast 6mm! Then I discovered the Badlands bullets with an outrageous BC for basically the same weight projectile. How could I not build one now!?
The designer of the wildcat I'm building is running things through quick load to get a conservative estimate on where velocity could be with my shorter barrel.

My 22" 6 Creedmoor runs around 3050FPS. I'm going to do some testing with the 100 BL also in the near future. Pretty sure I can get more out of it with some other powder.

I have a 6 SST being turned up as we speak with the 100gr SBD II in mind, I have 200 bullets in hand. I'm having a Bartlien 28" Heavy Palma, 1:7 5R being chambered as well as a 28" Proof CF Sendero in 1:7.5 Im going to give a try just because that was the fastest CF twist I could get my hands on, I figure if they don't work in the 1:7.5 I can still use it out of Ca. with any of the Bergers, 105 Hybrid, 109 Hybrid, the 108 Hunting Hybrid and so on. I know I can push 115"s over 3450fps no problem so the 100gr SBD II's would be lasers out of the 6 SST. I may not get them to work out of the 1:7.5 but I think Im going to Place an order for a couple Bartlien CF 1;7 barrels just in case, I think a 6 Dasher set up for the 100gr SBD II would be a great Antelope and deer cartridge.
I was thinking of having a 1:6 or 1:6.5 Twist made for the 100gr SBD II but if the bullets didn't shoot out of it then what do you do, it would pretty much be a one trick pony. I do shoot the 79gr BD out of my 6x204 and they are great and Kill! I think they list them as the 80gr BD now, I bought them before they were on the web sight and they called them the 79gr BD.

That is exactly how I felt about the 250 SBDII .338. With a .410g7 it turned the 338 mega or even your basic 338wsm into an effective 1k elk gun even from a 21-22" barrel.

The 100gr does the same thing for the 6mm. You run out of energy before you run out of vel.

The issue is if you choose a truly designed ground up hunting bullet in lead core it does not have the bc. If you choose a high bc that is trying to be a hunting bullet berger, elds. It's a compromise. There are failures and range vel window matters. But with these turned monos now you get excellent hunting peformance and great bc. Using the higher density copper alloy gets you the density close to lead core for a better bc for a given length bullet.

Anybody tried those little 100gr 6mm dozers out on game yet?

I saw somewhere, someone had loaded them in a 6sst specialty pistol, but that is about all I have seen. Those in a heavy 6-284 would make a sweet pronghorn setup out here......

I have a friend in town whose company makes custom hunting rifles using carbon fiber stocks and carbon wrapped barrels using ultra high density carbon wrapping and stock material made by Paradigm. He is a big user of our bullets including the 100 gr .243 BD2. A customer of his, for which he developed a load in a 6mm wildcat based on the 243 Win case killed 3 pigs at 150 yds at a feeder with one shot, attesting to the extreme penetrating ability of these bullets. I have had no problem hitting targets at 1200+ yds with these bullets. They are perfectly suited as long range hunting bullets out to at least 1000 yds and at that distance the combination of high BC and reliable expansion down to 1700 fps make them a true long range hunting bullet. I personally would not hesitate to shoot Deer or Elk with these bullets at extended ranges (beyond 600 yds). They do require a 1:7 twist barrel to function properly. As always shot placement in the vitals is key to a quick kill.

Just to make things clear for the readers, which cartridge requires a 1-7", .243?
