Most of us post up to seek or share info/comraderie. Some post only really looking for a good ol' pissin' match.

I've 'gone there' a time or two, but it's not really my thing. Entertaining to read sometimes.

Not that I feel compelled to answer Phuckeye's post, but here is a picture of some 25 caliber bullets.



The picture shows bullets that I have loaded for in .25-06. The two bullets to the far right were made by Wildcat Bullets. The second from right is 125g ULD and far right, 130g bonded bullet. As you can see with the bonded bullets, they are quite long.

In my 1:10 twisted barrel, they didnt shoot well. Not sure if a coincidence or a twist issue. No keyholing though.

So to answer your question, Wildcat Bullets did make a 130g bullet. With new ownership, not sure if they still are.

Despite your illustrious artillery experience, I see no formula, nor a reference to a ballistics engineering degree (perhaps you have one) So, I guess I will call Sierra someday....


Unfortunately I don't share Shane's coolness, so you can shove a 130 bullet right up your ass Phuckeye.


grin

and as we like to say in WI....WTF's a Buckeye.

The one thing that hasn't been mentioned so far regarding twist, and why slower twists work better in larger calibers is because twist affects the surface speed. If you spin a .35 caliber bullet in a 1:10 at the same velocity as a .25 caliber through a 1:10, the outside diameter of the .35 will be spinning much faster than the .25 The center of the bullet will be spinning at the same rpm, but not the outside of the bullet.
So that's why it takes such a fast twist in .22 calibers to stabilize bullets with a lower sectional density, length, or BC than a .25 cal of the same weight.
Make sense?
And, no I'm not a ballistic engineer. If I was, then the term for "outside diameter speed" would have come to me, but it didn't.

If you need a 130 gr for a 25-06 just buy a 270

You are mixing angular and linear quantities here.

I know, help me out with the terminology. But the idea is correct right? Larger diameter bullets need less twist than little bullets, which is why a .22 needs a 1:7 for long match bullets and .26 needs a 1:8 for even longer match bullets, and a .338 does fine with a 1:10 with 300 grain match bullets.
Right?

Sums it up quite well. Guy deserves a in person, back of the neck held, face in the dirt.....held long.

angular velocity

Outside of a larger diameter bullet has farther to travel to get all the way around. Since the rotational velocity is the same given the same twist and the same linear velocity, the larger diameter bullet has a higher angular velocity.

What I don't know is what that has to do with stability.
