Subject: Winchester Ammunition Develops .45-70 Gov’t Load Ammo In Ballistic Silvertip
Morgan, UT –-( The Winchester Ammunition heavy-hitting .45-70 Gov’t classic is getting an upgrade in bullet performance for 2010 in the Supreme® Ballistic Silvertip® line.The new bullet design was co-developed with Nosler® and incorporates a plastic tip to help prevent damage from recoil and improve downrange performance.



The 300-grain bullet also features a black oxide coating to help reduce barrel fouling.

The .45-70 Gov’t bullet has been around for more than 100 years and was originally adopted by the United States Military in 1873 to be used with the single shot Trapdoor Springfield rifle. It later became a popular cartridge for sporting use and is ideal for hunting big game animals, such as whitetail deer, elk and bear.

The polycarbonate tip, like that featured on other Winchester centerfire bullets including: XP³®, Accubond-CT® and e-Tip®, prevents deformation in the magazine, boosts aerodynamic efficiency and initiates a large expansion at a variety of impact ranges.

What does .45-70 mean?

  • .45=caliber in decimal inches (ex. .454 inches)
  • 70=the weight of the original black powder charge calculated in grains (*Note: smokeless powder is used in the new Winchester Supreme 45-70 Gov’t load.)

“The classic 45-70 caliber now loaded in one of our most popular rounds, the Winchester Ballistic Silvertip, is really a unique combination,” said Brett Flaugher, vice president of domestic and international marketing and sales for Winchester Ammunition.

The Supreme® Ballistic Silvertip® .45-70 Gov’t will feature:

  • Bullet Wt = 300 gr
  • 20 rds/box – 200 rds/case
  • Availability: May 2010
