Question on Badlands bullets

[codyadams]

From my experience, they seem to attain velocities between what you would expect from a Barnes, and a standard cup and core, at least some of them. For some reason the 140 .277 bullet runs as fast or faster than c&c bullets do, but the 205 .30 cal runs about like a 215 Berger. I would look at a cartridge that would run a 168 Berger at 3000-3100 comfortably out of a 22", that way you will for certain have enough hp.

Thank you! This is exactly what I was looking for.

Since going 1-7t and custom I would go 7RM and not worry about availability or if a new cartridge will get popular or not. Should work perfect for what you are looking for

That's what I'm thinking but I'm sure I'd have to wait awhile for 7t barrel.

PacNor makes them.

I think it has a lot more to do with terminal performance than people give it credit for, especially when you get into heavy for caliber bullets, they want to tip over and the only thing keeping them going straight is the spin. A bullet would actually be more stable flying backwards. After seeing bullets make a 90 degree turn or fold like a banana once they hit an animal I think the only explanation is they were under spun and not stable enough. I run 6.5T in my 6mm barrels, 7T in .30 cal , and 8T in my .338's, hunting guns running monos not comp rifles.
And yes, it takes a long time to order a fast twist barrel, longer than getting a Manners stock.

I agree that terminal HAS shown that a increase in twist has helped , spin is only part of the equation though

Yet it is only a Band-Aid & the bigger one is to get the companies to start to look @ how a well balanced pill vrs a pill that is less balanced behaves terminally & reacts terminally once in the critter is created for us so we get better results

So get out there people & push all the companies to get better balanced pills as we all win

I'm not going to go into any specifics but it has been done with a couple of companies in various formats but always room to improve right

But a little extra twist doesn't seem to hurt either ( still working on that & more testing is underway soon ) so a good insurance buffer for what we use today regardless of brand

Nice post

Cheers

So JayR01,
Did you build a 7PRC with 7tw for the 160g Bulldozer 2? How does it shoot?

I ended up with a 7Mega with a 22" 7tw. Hopefully, I'll have the rest of my brass fire formed next weekend and can start load development with my 160g SBD2. I'll post an update when I do.

I'm looking forward to your results with that 160BD-2 in the Mega. Send some pics.

I'm interested in the OP's build too; but I'm going 7 PRC with Defiance classic action, Proof CF 22" barrel, 8 tw. I've ordered the 150 BD2 (best BC in a copper monolithic bullet that would stabilize in my barrel). I'm shooting the HH 170g in my 28 Nos at 3150fps with good accuracy. I'm hoping about the same with the 150 BD2 in the 7 PRC.
