Badlands Precision Bullets thread - From BC to terminal ballistics

That is a massive internal wound. Deer surprise me sometimes how far they go with wounds like that. Remind me of Black Wildebeest. If they know you are there they seem to not drop as quickly perhaps because they are pumping more adrenaline prior to bullet impact that delays the drop in blood pressure and maintains brain perfusion a few more seconds.

Yep, white tail are genuinely incredible creatures. Their will to survive is second to none. As I think back, the blood trail was likely light because the shot was high on the lungs and the heart was damaged. So, lots of blood but no pressure in the system. At this point the deer is basically just leaking inside and you don't get blood flowing out until you fill the chest cavity to the level of the wound on the body. No different than over filling a glass of water in the sink. Her chest cavity was filled to the brim with blood upon dressing her, though.

Finally got around to getting the last of my gen 1 125g BD's used up and got a load figured out with the 2nd generation 125g BD's to use this year!

So far they've been great, pretty small sample size for kills but data is data.

Custom 6.5prc, 26" LT Palma 4 groove 1-7 twist Krieger barrel with a Origin SA
56g RL 23 going average at 3217fps
2.284 BTO (don't remember the exact thousands off, will update)

The white tailed deer were around 235-245 yards, impact should've been around 2781fps.
First one took two shots, she was the bigger of the two. First round entered the neck and came out in the opposite shoulder destroying the bone in that shoulder, never seen so much bone fragmentation! The deer then tried to get up after a bit and I launched one into her head, right in front of her eye and it came out her neck(lights out). I did find a fragment of copper in the destroyed shoulder, not as destroyed as if I would've used a non-bonded cup and core I believe.

Second white tail was farther, it was a bang flop neck shot.

What's your twist rate and which bd2

What's your twist rate and which bd2

Forgot that, sorry brother!
Updated post with the details of that.

Just got in some 125's and about to start some load work up for my 6.5 Creed. Hope the standard Forster seating stem works fine. Any suggestions for a good load without reading all 99 pages?

I'm going to the range tomorrow with my 6.5 creed with the 125s to do a ladder test with H4831 I did one with h4350 and got heavy bolt lift at 42.0 gr velocity was 2815 and it's a tikka so they tend to run a little slower. But my forester seating die left rings on the bullet so I had to use my Redding seating die

On a solid copper bullet, does it really matter if there are marks/rings? I wouldn't think so but who knows, I may learn something!

Probably doesn't but my OCD is a completely different issue

I hear ya! Certain thins I'm like that with and some I'm not. My seating stem has more like a rub/scuff marks.

 

[IHFarmer07]

Max bto is 2.314" and I'm at 2.284" so .030 off.

00 steel wool makes those marks go right away on mono bullets.

I need less steps in my reloading process not more! thanks for the pointer tho that's good to know I'll give it a try

I was able to fill my cow tag on Monday and got to see how the 0.257" SBD2 110gr performed on elk for the first time.
Rifle was PBB 26" 1:7" twist 25-06AI
MV was 3500fps suppressed
Impact velocity @ 200 yards was 3252fps with 2583ft# of energy. Elevation was 8200'

First shot was broadside and impact was low on the scapula near the first joint which totally shattered the bone as seen in the photo below. This bullet appear to also hit in the far forward lung area and I believe stopped in the opposite quarter as there was no evidence of an exit. I will investigate further when I debone the quarters.

After the first hit, the cow took a couple steps and wobbled around a bit, but still stayed in my small shooting lane. After she turned 180 degrees, I took a second shot with the cow very slightly quartered towards me that hit high shoulder. This shot got both lungs and exited about 5" in front of the last rib on the opposite side. You can see the exit in the grip and grin photo. The larger hole in the photo below shows the entrance cavity of the second shot and there is a smaller wound to the upper left of that hole which is the exit path of the first shot.

Upon inspection of the lungs there was copper fragmentation found between the lobes. There is a small fragment shown in the photo below.

Overall I was very pleased with the performance of this bullet on elk. The animal expired quickly, only a couple yards from where she was shot, and there was very little meat damage.
My bull tag starts tomorrow and I am very comfortable launching the 110gr SBD2 at a bull inside 400 yards after seeing how it performed on this large cow. I have only seen a spike so far so wish me luck

Looks like about 2.925"

I'd just do the 125's I ran the 135's @ 2.980 and it was the absolute shortest I could go.
