150gr Badlands Bulldozer 2 experimental broaching test. Will they expand faster/sooner on impact?
HTML-код
- Опубликовано: 5 авг 2024
- Ballistic gel testing experimental heavy broaching on the 30 caliber 150 grain Badlands Bulldozer 2 to see if they would expand faster/quicker on low velocity impacts.
I used an 8 inch 300 AAC/Blackout pistol 1:7 twist for this test. As can be seen in the video there is no noticeable difference at lower velocities.
Have you considered doing any gel testing of the Apex Outdoors mono bullets? I think your approach to this testing is far more valuable and realistic than most of the impact testing I have seen. Keep up the good work! :)
Glad you decided to do these, I've been shooting the first gens for 3 years now and it's a great small company with high-quality bullets! I will try my Badlands Bulldozer 2's some time in my 6.5prc.
another solid video Josh keep up the good work!
Thanks for the test. Monolithic bullets will be the future regardless of what we want. They keep getting better and expand more reliably. I'd like to see you summarize your vast experience with monolithic bullets including their accuracy
I have use/used the 120 gr GMX and CX in my 6.5 Creedmoor, 225 gr TTSX in a 338 Win Mag, and I just finished up load development for the 140 gr Bulldozer 2 in my 6.8 Western but still need to use it in the field. They all where/are very accurate.
your videos are getting better and better my friend!
Thank you. I try to heed people's advice and I learn as I go.
Great job as usual my friend.
Thanks, glad you enjoy
Interesting. Thanks
Please more Videos!
I know, I am way backed up and the RUclips channel has not been getting priority. I really need my time off to coordinate with good weather.
I actually did a gel test with the 55gr BD2 at multiple distance (50yd, 100yd, 200yd) and all impacts open within 0.75" of the others, at around 6" into the block. The 55gr and 62gr have very "abbreviated" noses compared to the entirety of their lineup. I got the bullet to expand within 0.5" by cutting the stem of the aluminum tip in half. I pulled it out, cut the part that inserts into the hollow point, then put it back in.
It's the hold onto the tip that delays the expansion. Longer tips and longer noses help loose the tip better than short ones, and shorter and looser stems will come out WAY faster.
That is interesting how you cut the stem back and that it made it expand that much faster. Most likely it ejects the aluminum tip much quicker resulting in the more rapid expansion.
Have you talked to George or Jason at Badlands about your results? Maybe there is a reason they have the stem as long as it is and if not and they can simply cut it back to get the bullets to open faster that might be something they would offer in a product line.
@@simplemindedfella I have. When I got my custom bullet made, the original stem length was about 0.195-0.200", and I was able to get a stem length cut down to 0.170". He says he can only cut it so short due to the machine that holds them. He says it wince-inducing seeing how close those extensions get spinning at those RPMs.
He also alerted me that while gel tests tend to show an expansion depth of 3" or more, they always get reports of finding the tips between the entry side ribs and hide. While I think the 55gr/62gr versions will be more delayed, I think my longer nosed 59gr bullet (higher BC than both, with a speed that is very close to the 55gr) will open in the typical fashion/depth...maybe even faster, as he apparently used a "new" drill on it, the broaching goes closer to the nose walls, and the opening is razor thin behind the aluminum tip.
@@calangel I shot 2 animals with the 225gr 338 BD2 this year. We found both aluminum tips in the meat of a shoulder when butchering, though I cannot say if it was the close or far side.
@@z987k it's definitely the near side, as the bullet can't expand till it looses that tip. You'd have an icepick wound the entire way through the animal if it was the far side shoulder.
Do you remember how far into the shoulder you found it? What velocity and firing range?
@calangel I said I cannot say, just because I cannot say for sure, since I don't know which shoulder was which by the time we were butchering them. It should certainly be the near side though.
Nether were shot in the shoulder though, both just behind it doing very little to no damage to the shoulders.
First animal was at about 70 yards, second was about 220. MV of 2850fps.
Both seemed to open faster and penetrate straighter than other tests before.
I get what you're saying. I miss spoke in one of my videos (PT2 of the 175 gr 30 cal test) not liking what I saw and not going over it in the detail I should have. I apologize for rushing that test.
I'm actually getting a really consistent rate of ones that come out of the side of the blocks versus perfect straight line penetration but none of them veer enough to have any kind of concern do to it.
I have noticed that the down to about 1600 FPS to about 1750 or so they get a 1/2 inch or so less penetration before the bullet opens then when you get much over that 1750 to 1800 plus mart they penetrate a little further and I'm thinking that's because of how it sheds the aluminum tip in relation to the speed their traveling through the gel and that the hollow/broaching section has three stages of thickness and that aluminum tip allowing it to penetrate a little further from the speed yet you get high enough velocity and it counteracts that and opens it up quicker everything within those velocity ranges is still very consistent with each other and in most cases is not noticeable with the naked eye. They all seems to start their business within 2.5 inches to just pass that 3 inch mark. (As long as it starts mushrooming within 6 inches and causing good permanent wound cavities it will work well in game)
Depending on caliber ojave actual front bearing surface you will see slight variations from bullet to bullet not so much in grain weight changes but more so in caliber. Anything that changes the bearing surface can change that result slightly.
After this latest test, how do you feel about the minimum impact velocity for this specific bullet? I know for the 175gr videos you said about 2000 feels right. These 150’s seem to be opening more quickly at low velocities than the 175. Would you guesstimate around 1900 or stick to 2000? That 100 fps adds a lot of range. Granted, it’s extra range most people will never use, but for a 308 it might mean the difference between go/no go at 500 yards, which is still within reasonable ranges for something like pronghorn.
They haven't failed at 1600 fps and above for me. I always like to stay 100 fps or more above minimum just to play it safe. These in a 308 should (depending on one's muzzle velocities) be good well past 500 yards.
@@simplemindedfella good to know. Appreciate all the feedback. I ordered some earlier today and can’t wait to try them out. I have Varget, CFE223, and TAC for powders. I think I’ll start with Varget for the stability. The bc and low velocity performance are so good that I don’t think the extra 50-100 fps I might be able to squeeze out of CFE is worth the decreased temp stability. Plus it’s just been the easiest of the three to get accuracy out of without too much load development.
💯 Promo sm.
