Superb Bullet Tolerances from Berger!

[Ahhnother8]

Because whoever is setting up and running the bullet machines deserves a big, wet, sloppy kiss. The minimal range of the tolerances is simply outstanding. Sorting is almost getting to the point of being a waste of time.

I wish they would work overtime and have more calibers running. Im wanting some 20 cals.

What bullet and what are the numbers?

Then stop and practice more!! LOL!!! Please see the link to see what tolerances we check IN A LOT OF BULLETS ! Not ACROSS LOTS of bullets.

Why Berger's Are Better

We use only the highest quality copper and lead available to eliminate impurities or other material issues. All bullets are made with one die.

Depends on the bullet. I've found that Berger OALs can be inconsistent enough to be worth sorting for long range high precision shooting. That said, Berger does a pretty good job.

Oal ... That better be the same... Same jacket.

Bto is the important measurement. Imo
I stopped using burger because of the bto.
And their cost compared to customs.

I had a spectacular lot of Berger Bullets that I bought in the summer of 2023. Not sure if they were from a new set of dies or what. Really impressed and hope it continues. Well done to the production staff.

Brian Litz said on a podcast with Erik Cortina that in an OTM style bullet, the OAL is the most important sorting method to use. He feels that the BTO is hardly relevant anymore compared to the OAL and how it affects its use for long range...

I've sorted a couple of different calibers and weights of Bergers ( the pointed ones ) and they vary at least .010 in OAL
And if you buy a different lot, forget it.
Maybe some of their bullets sort better than others.

Yeh,
If he spent more time practicing and less time sorting he probably wouldn’t have dropped those 4 points while running away with the Cal State Midrange F-Open Championship last weekend.

After seeing this ; I decided to check some of my Berger 185 Jugg Targets . Spent about fifteen minutes checking BTO and OAL . Found a few that had greater deviations than .003 , so I'm not going to worry about it till these three thousand from this lot are gone . I guess if you are after "perfect" and a "guarantee", A new refrigerator , or one of "Brandon's new pool pumps might be on the list .

Were they talking about loading these bullets to magazine length? OR? Our OTM bullets are TANGENT OGIVE bullets that are normally used for magazine length loading situations.

No idea. Ask Eric if it was due to vertical or horizontal movement of the bullet to prove your point.

 

[dcali]

In my experience, if the OAL is consistent, the BTO is consistent, and OAL is more important because BTO varies very little in good bullets and OAL has a measurable impact on BC. Perhaps this is not always true, but it has been in my experience with high BC match grade bullets.

There's only so much you can do about the OAL variation - jackets themselves vary a little, and that just gets worse when you stretch them out. The longer the bullet, the harder it is to keep them consistent. Berger (in my experience with their long range bullets) does about a good a job at that as you can with mass produced bullets (any bullets really), but they're not perfect and still benefit from sorting by OAL (for F class levels of accuracy).

Geez, I was trying to make a joke.
Lane has a theory shared by a lot of BR shooters, EVERYTHING matters.
Whether you can prove it or not is another question altogether.
He also happens to be one of the best wind readers in the country, that helps
Sorry if I ruffled your feathers.

It doesn't matter what application you use it in, he explains why the projectile OAL is more critical than projectiles BTO. He wasn't meaning COAL, but was answering a question regarding bullet sorting....

No feathers ruffled, and I agree whole heartedly with you on " that everything matters" Just asking a question. thats all.

Its funny they pick the OAL of the bullet. That is usually the biggest variance i there is in a box of bullets. They must be looking at the affect on BC. ( Which as stated by Emil Praslick IS 1% OR LESS IN A BOX OF BERGER bullets). So now we are into meplat uniforming / bullet tipping to make the BCs more consistent ( meplat uniforming) or bullet tipping ( increasing the BC) If you are a master class shooter such things can make a difference in the VERTICAL dispersion of the bullet strikes. But not so much with a shooter who hasn't reached that plateau yet. They need to PRACTICE to get there where they can see some benefit from all this.

 

[dcali]

OAL variation absolutely has a significant impact on BC *if you are shooting in high precision disciplines like benchrest and f class*. All bullets by every manufacturer vary. Some more than others. The Bergers I use most - the .22 90 VLDs typically have a range of 0.020" in a box. That matters for F class. They're still exceptional bullets, but it is what it is.

I have yet to see a good bullet with a BTO variation that matters.

Crass self-indulgent plug: There are some tricks that can be done to minimize length variation - I sample 25 of my 6mm bullets out of each batch. After some processing and equipment tweaks they typically have an OAL extreme spread of about .005" and a SD of roughly .001". This is because of the way the tips are formed and some changes to press geometry. I'm pretty proud of this.

I also like Berger bullets.
