Bullet Sorting Methods

[Alex Wheeler]

Most of the accuracy gain will come from base to ogive sorting. In my experience bto will correlate to bearing surface as well as other measurements. BTO is also an easy one to do, bearing surface is a more finicky thing to measure and I dont think you can do it as accurately over 1000s of bullets. Reports I am hearing on the latest batch of vapor trails is you cant really sort them they are so good, but like Matt says you still need to do it to find that possible odd ball. The Bob Green tool measures 2 points on the ogive and will help find bullets with a different nose shape which will effect bc. I think its a good tool. I did the BC math one time on bullet weights. The difference in weight is canceled out by the bc change it causes. I dont weigh bullets. The other thing to do is sort by oal base to tip. If your not trimming and pointing.

Buy EPS bullets you don't need to sort them I don't any more it nice not to have to do all that sorting any more.

I used to shout accolades to my bullet maker du jour too.......until I upgraded to better sorting tools from Sinclairs P.O.S.

Please explain how this hits two points of the ogive? Is it custom for each type of bullet?

It is possible everyone has one of these but I never read about anyone using one.

I have several!

Larry W. was bragging about inventing the 3 point contact and I wondered why all of the reloaders got all giggly. And then I figured it out; none of them ever milked a cow on a four legged stool, I prefer the full circle contact.

I guess that means you have three or more; if you had two you would have a couple. In my opinion I do not believe there is a more solid tool made for measuring + or - after adjustment.

Yes, I believe I currently have five. They are a great tool. But for accurate measurement it helps to have a certified gauge pin to set it.

It is like a seating stem with a smaller one in side, the one inside slides. Does that make any sense? Best way I could think to describe it.

so you do not care if you have a bullet that is 0.5 light ?
i just finished sorting 200 bullets.
ONE was 0.5 light. at 1000 that makes no diff of the bearing length is the same ?
(most were plus or minus 0.1 with a few at +/-0.2)
( i do both for long range bullets)

Plug it into the bc equation. Then mess with a ballistic calculator and quick load for velocity and drops. When I did it, it canceled out. I never have sorted for weight and have never had flier problems. Thats just my experience.

Just finished going through my first two 500ct boxes of Berger 105g Hybrids, only to find my just purchased two 500ct boxes, lot C155 are .034" shorter OAL and .037" shorter BTO. Appears that most of this is a change in the boat tail area. Now it's back to load development all over again......sigh.

My dog asleep at the base to ogive sorting job! Tried teaching the old lady, that didn't go so good.

Base to ogive is of the more important things IMO. At two different diameters even better yet.

Nice piece of equipment. Looks like a great guard dog. But the pic begs a host of questions ....yet too much info sometimes is not a good thing.

That the Accuracy One sorter Tom? Haven't seen it mentioned here but looks like a very well thought out piece of equipment.

I have read until I have information overload on this subject. At this point I'm a raw rookie loading 200.20x's without sorting them at all. I have 900 split between 2 lot numbers. I'm almost afraid to start sorting them. Perhaps less information is a good thing sometimes.

With all those beer cups, I think the poor dog got overserved while sorting!

Focused oscillating magnetic field sensor using eddy current measurements

An X-RAY of the bullet in short, and yes ,i own one

It's not a Juenke

This may be necessary, lol, but seems almost OCD

Shoot More, sort less

This doesn't work well if you shoot long range BR. You will actually shoot less because you won't make the shootoff. Matt

 

[suasponte]

You'll gain more learning shooting in the wind then sorting (QUALITY bullets) any day.

Maybe in F-Class but not BR. BR is all about groups. Wind isn't near the factor. You sometimes lose by less then .010. Matt
