NOTICE- 17-556 Was created by KAK Industry and is our proprietary chamber design. This chambering is NOT cross compatible with similar cartridges, do not attempt using other rounds in the 17-556 chamber.

 

We wanted to use brass that was plentiful and inexpensive, like lake city 5.56 military brass. We developed sub .5" loads or better with powder ranging from 4198- Ramshot Tac in correlation to the burn range data. Base loads can be worked up from 17-223 and 17 Remington load data for a base load. While using 20 gr bullets, and even faster with 15.5 gr. Velocities from 4200-4600 (18" version, TBD 21" version) fps depending on charge and bullet weight is what we found to be optimal with this barrel.

We are producing KAK Industry 17-556 Custom chambered barrels for this cartridge currently.

Our Custom Chamber Reamers offer improvements such as reliable extraction, no neck turning needed, and the correct amount free bore in correlation to these light varmint bullets liking a jump to be accurate.

The barrels have optimized tweaks to aid in reliable extraction.

We worked with Redding to produce dies that match our chambers perfectly.
