HSM Varmint ammunition in .243 Winchester (brand part no. 24315N) is built for shooters reaching out on prairie dogs, ground squirrels, and coyotes. HSM backs this load with the quality control shooters expect from a name they already trust. At the heart of this load is the 70 gr bullet with a sierra blitzking design, matched to the .243 Winchester platform shooters already run. In our rifle ammunition lineup, this is the HSM load built for that job.

Key Specifications

• The bullet weighs 70 gr, sized for the terminal performance this load is built around.
• The projectile is a Sierra BlitzKing design, designed to fragment violently for explosive terminal effect on small targets.
• Each box holds 20 rounds, enough to work with before needing to reorder.
• Cases ship 25 boxes to a case, a useful case size for stocking a range or defensive supply.
• This is a centerfire cartridge, ignited by a replaceable primer rather than a rimfire priming ring.
• The Sierra BlitzKing’s polymer tip drives into the jacket on impact, fragmenting explosively for instant knockdown on varmint-sized targets.
