Description
Build a practical 100-grain soft-point load you can understand and prove
You want a useful .243 / 6mm load built around a substantial 100-grain bullet. You want a traditional soft-point mechanism, a flat base and a component whose construction is stated plainly. This Viper gives you that starting point.
The soft point is the intended expansion mechanism. The low-drag nose gives the bullet its aerodynamic design direction, and the flat base defines this version’s physical architecture. It is the direct Viper choice for a handloader whose assignment does not require the ultra-low-drag rebated-boat-tail configuration.
This listing contains 50 component bullets. Cases, primers, powder and loaded ammunition are not included. Gold Country hand swages these bullets in small batches. They are made to order and normally ship within seven business days.
What this bullet helps you accomplish
This Viper lets you develop a 100-grain load around familiar design principles without treating every soft point as interchangeable. You can tune seating depth, cartridge overall length and the rest of the loading system around a known nose and base form, then evaluate the finished cartridge in your own rifle.
Choose it when the low-drag soft point and flat base fit the assignment. Choose the Viper ULD rebated-boat-tail version when you want its more geometry-focused aerodynamic design.
Why buy the Gold Country Viper
The value is a hard-to-find combination made available in a useful development quantity. Gold Country identifies the complete construction, makes the bullet in a small batch and gives the serious handloader a component around which a purposeful load can be built.

Make the evidence in your rifle
Soft-point construction and low-drag geometry state the design intent. The complete load determines the result. Use current published jacketed-bullet data for the exact cartridge and weight, verify seating depth and cartridge overall length, confirm chamber fit and function, and test the finished load in the rifle and conditions for which it is intended.
