600 Bergers Sorted by Bearing Surface!

Results from sorting 600 bullets 0.308 caliber 210 gr. Berger.



My understanding is that to shoot at 1K you want to sort them with-in 0.002". From goodgrouper's experience seems like 0.002" at 2K will give a large vertical spread. I have also read that you want to sort them with-in 0.003" from Bearing Surface manufacturers, I could be wrong, but they don't say what distance they're good for. I'm limiting my shooting on paper to 1200 yards . 539 pieces which is 89.83% fall within 0.002" and 412 pieces, 68.67% fall within 0.001". All comments are welcome. Would it be good enough to sort within 0.001 for 1200 yards?

Eaglet,

Good work!

I would think that data shows that the Bergers are darn decent.

You now have the bullets from both sides of the bell curve to do a little testing.

I like your attention to detail.

Good post.

Thanks, Roy & E.Shell.
I took quite a while, but the work it's just begining. Like
Roy says, now I can do some testing.

It would be interesting to know if you loaded the odd balls and the ones long and short ones if you could tell the difference!! say at 1K.

See if they change the conograph speeds.

Now you better weigh them all!! [img]/ubbthreads/images/graemlins/smile.gif[/img] [img]/ubbthreads/images/graemlins/smile.gif[/img]

maybe check the over all lenght!! [img]/ubbthreads/images/graemlins/smile.gif[/img]

Thanks for posting the info

PS what part of Nevada are you from?
have you shot at the Reno gun range?

No, he should cull all the one's that are out of spec and give them to his buddy to shoot. I can't get any Bergers within a 100 miles because Eaglet bought them all.

Eaglet, you've got too much time on your hands. Why don't you try to get a job or something. Give me a call. I'll take you to lunch.

Re: 600 Bergers Sorted by Bearing Surface!

Eaglet,

A suggestion if I may, ok?

My natural tendency would be opposite to this, which I'm pretty sure makes this a good idea, I think. [img]/ubbthreads/images/graemlins/confused.gif[/img]

Burn up those ones on the ends of the bell curve last. Use the ones near the peak to do the tuning etc. Get those SDs and ESs and groups where you want them.

Then shoot your developed load with the ones on the fringes and compare the performance.

The only reason I suggest this is that I'm just too lazy, selfish and a scab to do it myself. [img]/ubbthreads/images/graemlins/crazy.gif[/img]

Whatever you do, let us know how thing turn out.


Cheapskate mooch Roy, signing off [img]/ubbthreads/images/graemlins/blush.gif[/img]
