Re: Bullet Stabilization Questions

Well guys,

I'm a little surprised that with the amount of shooting you do you haven't heard of anyone trying that. One person even made a completely round based bullet and shot it backward to see what happened.

Again, I have no first hand experience but since I've heard this so much from so many people, I assumed that if you made your own bullets, you had to try this for some reason or another. I just figured everyone did it!

BH, if I told you who one of the people was, you'd probably fall over.

Re: Bullet Stabilization Questions

Phil,
Do you suggest I download when I try a few?
Or does 3200 fps and the 210 JLK sound okay? Tomarrow would be a good day to experiment. [img]images/icons/smile.gif[/img]

Re: Bullet Stabilization Questions

Brent,

in the case of the person I talked to the most about it, He shot alternating shots and was shooting for group like that so I guess it wouldn't make much difference what you did.

Now that you mention it, I think I'll give it a try today myself.

Re: Bullet Stabilization Questions

OK Brent,

at least in my case, they seem to be stable. I chose to shoot a 14 twist 22 with 55gr Ballistic tips.

I loaded 10, 5 backward and shot them alternatingly.

The right ones impacted where they should and grouped normally. The backward ones grouped somewhat bigger, about 70% it appears and impacted low of the normal ones but dead verticle. This at a range of 110 yards. The pressure seems the same forward or backward (just looking at the primers), but the gun reacted different. It was as if the acceleration was quicker with the backward ones and the recoil greater. The difference was slight.

At first I thought they were complete misses. My forward shots were where they should be and there was no hole visible. Then after 3 of em, I saw the holes were punched clean and could see the light through the homosote backer where it had been punched clean out. Pretty neat.

As for what I learned... My ammo looks nicer with the ballistic tips out the front!

Re: Bullet Stabilization Questions

I kind a spaced it out this morning and didn't get any loaded up backwards and I'm ready to walk out the door now. Next time I guess.

Your test is interesting. Did any go through sideways?

Re: Bullet Stabilization Questions

No Brent. And for what its worth, the conditions were about as nice as I've seen this winter. I even put out a wind flag though I don't know why. The sky was calm today. Only problem I had is it's cold here. Not like where you live in the tropics! It was about 5 here this morning and I couldn't set up in the living room so I HAD to go outside to do this! Brrr.

Re: Bullet Stabilization Questions

when bullets exit a gun they are corkscrewing through the air in a circular patern.a yaw force is put on it from the spinning (torque) and it takes a while to "go to sleep".that is the center line of the bullet will be identical to the centerline of travel.did you ever take a gyro and yank the string out of it making it spin real fast.when you set it on the floor,it rotates in a circular pattern.the circles get smaller until it stayes in one spot,or nearly in one spot for a while,then it starts circling in a bigger and bigger pattern until it falls over.this is exactly what bullets do. put your gun on your best rests and shoot a group at 30 yds.i'll bet the group's at least an inch,and the "group" will be a circle,not a cluster.the longer the bullet is per caliber,the farther it will take to go to sleep.
as far as shooting worse,obviously the farther you shoot,the harder it is to hold whatever level of accuracy you and the gun can hold.when a gun shoots well,and then goes to h___ at a certain range,it's usually a stabilization problem.most paper punchers only spin the bullet fast enough to stabilize it for the distance they shoot.as it slows down its rpm's are slowing also and it becomes unstable.(wakes up)if you're hunting,you need around 50% higher rpm's for terminal performance.this is what keeps a bullet driving through an animal in a straight line.
