When using Berger Bullets, the serious rifle shooter can be confident of the fact that the “SHOOT BETTER, SHOOT BERGER” slogan we use is based on fact rather than marketing hype. Sure we are proud of our bullets and the efforts it takes to make them. However, there are very real science based reasons why Bergers are actually better. The points below are both factual tolerances and dimensions, or policies and procedures that we use to ensure our highest quality reputation.
We use only the highest quality copper and lead available to eliminate impurities or other material issues. Our material vendors have been in their industry for decades. We have regular meetings at their facility and ours to refresh our mutual understanding of our highest material quality requirements.
Our bullet weight tolerances are listed below. The actual results are usually tighter than these tolerances allow:
- 17 Cal to 30 Cal: +/- 0.2 gr
- 338 Cal: +/- 0.3 gr
Our bullet base to ogive tolerances are listed below. It is important to note that measuring this dimension is difficult as the point of contact is a thin and rounded surface. If you find measurements greater than the tolerances listed below please measure the same 10 bullets several times to confirm that your measuring device is reliable and repeatable (many on the market are not). We use a specially developed process which includes custom made gauges to ensure reliable and repeatable measurements. Most reports of bullets outside this tolerance are found to be the result of how they are measured:
- 20 gr to 115 gr: 0.003 ES
- 120 gr to 210 gr: 0.005 ES
All jackets, cores and bullets within a given lot are made with one die to guarantee consistency.
Each bullet is made on a die that is designated for that bullet. This die is set aside and used again for all lots until this one die wears out.
All tooling is precision made using dimensional tolerances in the .00005. Using precision-made tooling is an absolute requirement. The companies who make our tooling are specifically in the precision tooling business. We meet with them regularly to communicate our tooling needs and special projects. Those who understand precision tool making know that these things are possible but not without deliberate effort and experience.
J4 Precision Jackets are the only bullet jackets in the world known for less than .0003 total wall thickness variation on every size and lot. This has been true for decades and is provable by checking any lot. There are those who claim that they can meet this tolerance and we know that they can every once in a while, but to do this with every single lot is something that only J4 has perfected. Anyone who wants to can order jackets and check them yourself. This is an absolutely critical aspect of precision bullet performance and we are the only bullet company with this capability.
Berger will spare no effort in resolving a quality issue if it is determined that the bullets are bad. As hard as we try, we are not perfect and are capable of admitting this fact. Our process is set up to minimize human failings but these things can happen. If they do, I stand behind our quality and will make sure we resolve the matter to your full satisfaction. I will go even further and will openly communicate these situations so that we can prevent others from the same negative experience. We are committed to your complete satisfaction with our products and service.
