WELCOME

Good day and welcome to our Website. I am Gina Schultz, owner of GS Custom Bullets. My father, Gerard Schultz, started the bulletsmithing business in 1993 when he was full time in custom rifle building. In January 1999 Jani, my twin sister, and I bought the business when Dad retired and, still with Dad's help, started expanding the range to cater for just about every need we could think of. Jani joined her husband in his business during 2001. We look forward to meeting you, be it by fax, phone or e-mail. Of course we welcome visitors to our facility, so if you are in the area, do come and visit - and do remind us to take your picture for our visitors page.

Our site contains a navigation bar at the top and bottom of every page. This will take you to the main sections of our site. 

The Site Map is also handy for returning to pages you have visited before.

Every navigation bar has links to the Site Map, our orders pages as well as a "contact us" button that enables you to e-mail any questions you may have.

Any suggestions for improvements are always welcome.

We have a 24/7 Technical helpline and orders can be placed directly on this site. Order enquiries can be discussed from 8am to 6pm Pretoria time, with Gina.

I am Gerard Schultz and will answer your questions on the technical helpline. You can also contact me via email. Please visit our FAQ pages for questions that crop up most frequently.

Bullet Design and Q&A

GSC bullets are designed to the following standard:

Diameter tolerance: + or - 0.005mm (0.0002").

Length tolerance: + or - 0.10mm (0.004").

Weight is within 0.25% of the stated weight.

Uniformity of ogive curve: - + or - 0.005mm (0.0002").

This is an overall standard that is maintained from batch to batch - not just within a batch.
GSC drive band bullets are protected by SA Patent number: 1997/10275

Bullets are turned on computer numerical control machines.

All GSC bullets are turned from copper rod, sourced from an ISO9002 qualified foundry, accompanied by a certificate of traceability and quality. 

The machine room and raw material is temperature controlled from 22 to 25 degrees C to minimize the effect of expansion and contraction variables.

Copious amounts of coolant is used in machining to reduce heat expansion of the copper in the turning process.

Each cnc lathe is equipped with a measuring station with a scale, digital micrometer, digital vernier and a record sheet.

Once the design of a bullet is finalized, a card is created reflecting all the dimensions of the bullet, the size standard to which it must be made and with the actual cnc program on the back.  The bulletsmith uses this card to ensure that no detail of the bullet ever changes from one batch to the other.

Before a run of bullets is started, the 'smith will zero the digital micrometer on the appropriate size standard for the bullet.  If the 'smith leaves the workstation, the micrometer is checked when he/she returns.  When a run is closed, the micrometer is checked against the standard.  This ensures that bullet diameters remain the same from batch to batch, even when batches are months or years apart.

This is what we call a triple 9.  It is a part that is made before a new bullet run is started and every time a cutting tool insert is replaced.  It has 5 specific dimensions that are checked to ensure that all the tools are in the correct relationship to each other and correctly adjusted to start the run.

Here is the production record that is kept by the 'smith when bullets are made. This is a sheet from our files.  At "A"  the details of the 'smith, the bullet being made and the batch number are noted.  At "B" the 'smith marks the diameter size of every bullet that comes off the lathe. The grey lines above and below the tick marks are the upper and lower tolerance limits and, on this sheet, the 'smith adjusted the machine twice to maintain size.  At "C" is the roundness and taper check.  "D" shows the weight variance and each line is 0.10gr. This sheet is for a 640gr bullet and the recorded highs and lows span less than one grain.  "E" shows three tick marks for every bullet and these are for visual machining faults, bullet base quality and bullet nose quality.  "F" shows the start and end time of the record.  Rejects are also recorded in this section.  

The 'smith passes the batch to the QA and finishing department.  Here the bullets are washed and every bullet is again checked for the same parameters as were done by the 'smith - diameter, roundness and taper, weight and machining flaws.  This is done to catch any mistakes the 'smith may have let slip.  From here the bullets go to finishing and coating and then to packaging.

The QA department will sometimes fail bullets that were passed by the 'smith.  Such bullets are sealed in packets with the batch number they came from and kept for three years.

Throughout the process, random checks are made with separate calibrated measuring equipment to ensure standards are held.

Three 150gr 308 caliber bullets taken from three different production runs, spanning more than three months.

The bottom line: every bullet is checked against several parameters that are important, not once, but twice.  We believe we have a system that makes it as failsafe as is possible, to ensure that every bullet received by a customer is a precision tool. Our facility is open to visitors at any (reasonable) time. 

Primers, powder and cases may vary from batch to batch, but you can rely on GS Custom bullets to be
uniform from batch to batch, week to week and year to year.

More Accurate, More Consistent, Most Reliable.

These bullets are used by hunters on several continents, hunting from the smallest of antelope to the largest of dangerous game, using the smooth HP bullet, as well as the more popular HV, FN and SP bullets with the patented drive band concept. GSC bullets are configured for the highest possible ballistic coefficients. SP bullets are mainly used for sport shooting. All GS Custom Bullets are coated.
