Triple Seven 209 Primers
Winchester™ 777 Seven 209 Primers are specifically designed for Muzzleloading and burn milder than typical 209 Shotshell Primers. The 777 Seven 209 Primers do not force the powder charge forward in the barrel, helping to maintain consistent velocities and minimize formation of corrosion rings. Winchester™ 777 Primers are more sensitive, easier to seat, and more compatible with progressive and automatic loading equipment than ever before.
Winchester™ guarantees better sensitivity and positive firing in all guns, consistency in size and quality and stability in extremes of temperatures and humidity. These Winchester™ 209 Primers are constantly being tested and meticulously improved for field and target loads in all gauges. Primers come load-ready in 100 to 5000 count storage packets. These primers are not designed to be used in shotshells, they are for muzzleloading rifles only.
**Do not exceed the loads displayed in the loading guide. Never mix any two powders regardless of type, brand, or source. Never substitute any smokeless powder for Black Powder or any Black Powder substitute.
