HOLY mother of…

Do they plan on using any sort of bore rider design for the 180? Seems like you might start to get a LOT of friction and pressure issues if they don't with such a long bullet

Let me know when they come out if you remember, my next barrel will be a 7 twist so as long as that stabilizes it I plan on at least giving them a try and see if my gun likes them

Negative on the bore rider. None of their bullets have any. I do not know if you know Swamplord but he did a lot of tests with his wildcard without any issues.

I scored some Norma 257W brass from Raven Rocks Prec. on sale earlier in the year. I also picked up a couple boxes of factory ammo to try. The 92 HH factory load shoots under and inch and does 3704fps out of my M 307

I would still think you could see velocity gains by going bore rider or hammer bullets style ribs to minimize drag while it's heading down the barrel. But I still definitely would love to try some 180's when I put a new barrel on this rifle

Unlike solids/mono, except for DRT, C&C does not need it or is required, otherwise every bullet makers will be doing it.

Interesting, why is that do you think?

Bore-riders, banded design, drive bands, or whatever bullet x manufacturer calls them are primarily on monos/solids because copper is a much harder material than C&C bullets. Unlike the solid copper that most mono bullet makers use, DRT uses no bore-rider/drive bands because they use a compressed copper powder (not solid) that is more forgiving and acts like the C&C bullet.

If you search, a few threads here address it with varying degrees of technical explanations. Here's the late Jerry's layman's explanation.

Ahhhh that makes sense. Thanks for the explanation

Miss seeing Jerry's posts around here and the other forums I'm on, he was truly one of a kind.
