Bullet stabilization

Thanks John Boy.

A couple of links that were sent to me:

The science of ballistics can be complicated, as a note a while back I was reading somewhere about early ballistics concerning firearms.  It was said when rifling was in it's infancy some folks believed that projectiles shot out of rifled guns shot more accurately because Satan was able to ride one that was not spinning and steer the projectile off it's path.  Perhaps they were right.

What if you are using "The Holy Black"?

Here's another wheel I didn't invent;    (I cudda bean a Kantenda?)

They just called it gunpowder back then.

I never call it "holy black" I learned when young to use the proper tool for the job, the original gunpowder ain't always the proper tool for the job, can't make a jacketed bullet go over 3000 fps, sometimes that is the proper tool for the job. 

(Can just see the nasy-grams headed my way now.)

Not a nasty gram, but it is starting to be apparent that for hunting guns where the meat is going to be
eaten, that faster is not always better. Recent studies have shown that fast smokeless rounds that have
LEAD cores tend to spray miniscule lead slivers throughout the meat, even away from the impact channel

Now I do have a .375 H&H and I definitely would want it filled with smokeless if I was gunnin' for a Cape
Buffalo. My dreams were to go to Africa, but bad hands, and mostly new hobbies , ie: BPCR rifles have
changed those plans.

My new goal, maybe next fall now, is to go out west and hunt a buffalo. Not one of the ones that are
in a pasture and are essentially cows, but one where I have to work a bit for it.

Been using the Barnes X bullet for deer since 1993, 90 gr in the 243, for me, no matter the distance so far from 50 yards to 250 you can eat right up to the bullet hole.   Only ones we've ever got back are the 2 my brother has done frontanl chest shots on at about 50 yards.  Both were against the skin on the backside.

I think Roy and Elmer would have both loved them.   I'm sure on that they would have agreed.

Fiddler green witnessed a phenomenom that is common in large transonic projectiles, we explained the phenonemon, and now it somehow does not exist?  It is not "Bad stabilization" or "bad rotation" or "Bad flight".  It is a stable rotating mass being acted upon by an external force.   Precession is a law of physics, and I posted the link to explain it.  That you do not understand it is no call to insult those of us who do.

Thanks, to you Sgt. Drydock and tyo all the others that have witnessed this phenomenom. It seems I'm not alone as some have said.
