Maybe Steve will step in here.....a heavier .257 hammer Hunter would be awesome!

Im thinking they did. Back when I was getting parts together for the other build. I tryed to find the heaiest bullet that was made. And I couldn't find any thing on Matrix. That was a couple years ago.

The only problems with this is, Steve's bullets are mono's...These naturally already require a very tight twist, like a 1:7... If he goes any heavier, you'd need like a 1:5 twist barrel. Also, mono's are expensive as hell compared to cup & core. We need someone with a large enough lead bullet operation that would be willing to do this...Like Berger.

I was bore as hell at the house last year and turned some 115 bergers into, I'm thinking, 142 bergers...lol

How did you manage to do that? I've never messed with bullet making, but I'm curious to learn.
I wonder if it would be possible to swage-down some 6.5mm 130 AR Hybrid Bergers to .257" diameter... That's only .007" constriction... I bet the BC on that would be monstrous.
You are correct, but I think when Marshal sold it to the new owner, he (or the new owner) stopped making them.

Let me say that I would not ever try shoot them. I was just bored and had some extra cull bullets. I wouldn't suggest ever trying to alter a factory bullet. That could be very unsafe.
I was more or less curious to see what a tungsten core would change the weight of a bullet. Tungsten is not an ideal core for a bullet, for obvious reasons.

They can be swaged down with a proper die.

Now I'm curious to see if this idea would work, and how well they would work... Also, wonder what twist would be needed for something like this. Curious to see BC's as well.
Anyone have any proper bullet-swaging dies they can test this theory? If so, then we might have just figured out a cheap way to make heavy .257's...

Call Corbin. The correct terminology is you SIZE down and SWAGE up. You risk loosening the core though, and accuracy could suffer. Also, depending on the amount of hollow cavity, you could push lead out of the nose.

Gotcha! Thanks, didn't know the actual terms...
I wonder how hard and/or expensive it would be for someone who might already have the tools to get a set of custom dies made shaped like the Elite Hunter profile but in the 135 grain range for .257"... It seems nobody on the market is willing to go for it, but if we could prove it's worth, then maybe Berger would get on board and start making their own for us, at their normal affordable cost ($50-$55 a box/100).

It would be easy to do, just costs $$. I have everything for 30 Cal. It would probably about a grand to do .257 depending on what Corbin has in a std set or more likely, would want a custom.

Imagine the possibilities of pre-chambered and short-chambered barrels for .257 Sherman and .257 SS with a 1:7.5 twist... And selling the new 135 Hybrid bullets to match. I sense a cornering of a niche part of the market that is in desperate need of a reboot...

Ya, except I'm supposed to be retired!
