Designed for velocities below 3600 FPS, thin-jacketed and highly explosive, this can be one of the bullets for all 22 caliber centerfire handguns chambering medium-to-large-capacity cartridges for varmint hunting applications. Offering good expansion characteristics at all normal ranges with traditional Sierra match grade accuracy, this bullet may be an excellent choice for all but the smallest of the 22 centerfire cartridges. The Sierra Spitzer shape results in a high ballistic coefficient for flat trajectory, high energy retention downrange, and low sensitivity to crosswinds and vertical winds. The enhanced expansion characteristics on small animals make the Blitz the choice of knowledgeable handgunners the world over.

The #1345 was introduced in 1982.
