The Forster Bushing Full Length Sizer Die Kit in 6mm BR (Forster part no. FBK4279) gives handloaders precise control over neck sizing tension while it sizes the case body and bumps the shoulder in the same stroke. The body and shoulder are sized down just enough to chamber in a minimum-spec SAAMI rifle chamber, while an interchangeable bushing limits how much the neck itself gets worked, so your brass lasts for more reloading cycles before it needs to be retired.

Key Specifications

• Chambered for 6mm BR, sized to that cartridge’s case dimensions.
• Kit includes three interchangeable bushings (sizes 264, 266, and 268), so you can dial in the exact amount of neck tension your loads need.
• Sizes the case body and shoulder to a minimum-spec SAAMI rifle chamber in the same stroke as neck sizing.
• The bushing limits how much the neck is worked, reducing brass fatigue compared to a fixed, non-bushing neck sizer.
• Extends usable brass life, giving you more reloading cycles before cases need to be retired.

Frequently Asked Questions

Why does a bushing die extend brass life? Because the bushing only works the neck as much as needed for the tension you choose, instead of over-working it the way a fixed neck sizer can.

How many bushings come with this kit? Three: sizes 264, 266, and 268, giving you a range of neck tension options for the same case.

Does this die also size the case body? Yes, it sizes the body and bumps the shoulder to fit a minimum-spec SAAMI chamber in the same operation as neck sizing.
