Description
The Dirtnap .22 Creedmoor rounds from Fierce Firearms represent what you get when a rifle manufacturer decides to load their own ammunition to match their barrels. Unlike generic mass-produced factory loads, these are optimized for flat trajectory and long-range performance right out of the box. Each 77-grain Nosler projectile leaves the barrel at 3250 fps, delivering the velocity and ballistic stability that serious long-range applications demand.
.22 Creedmoor has earned its reputation in a crowded field by doing one thing exceptionally well: staying fast and stable at distance. The 77-grain match-grade bullet loaded here gives you a high ballistic coefficient without the excessive recoil that heavier magnum rounds impose. This load works equally well whether you're chasing steel targets at 1000 yards or running precision drills at 600 yards. The relatively light recoil makes staying on target between shots straightforward, and follow-up accuracy improves compared to more punishing cartridges.
Dirtnap Ammunition Line Performance
Fierce Firearms built the Dirtnap line specifically for the fast-twist barrels they chamber in their .22 Creedmoor rifles, but these rounds perform reliably in any rifle properly set up for the cartridge. The 77-grain option bridges match shooting and practical application, offering a middle ground between lighter varmint loads and the heavier 80-90 grain rounds. This weight stabilizes cleanly in 1:7 and 1:8 twist barrels while maintaining the flat shooting characteristics that define the cartridge.
What to Expect in the Field
With the .22 Creedmoor's combination of speed and high-BC bullets, you're working with a platform that handles wind better than older .22-caliber options and shoots meaningfully flatter than .223 or 5.56 at extended distance. The 77-grain configuration won't replace a dedicated predator bullet for terminal performance, but it excels for target shooting and competition work. Each box contains 20 rounds, and ordering multiple boxes scales economically with the 10-box per-case packaging option.

Frequently Asked Questions
What twist rate do I need for the Dirtnap 77-grain .22 Creedmoor?
The 77-grain Dirtnap load stabilizes well in both 1:7 and 1:8 twist barrels, which are the standard twist rates for .22 Creedmoor. If your rifle has a 1:8 twist, expect excellent accuracy. If you're running a 1:7, the extra rotational stability actually helps tighten groups further at distance.
How does the 77-grain load compare to heavier Creedmoor options?
The 77-grain sits lighter than typical 80-90 grain .22 Creedmoor loads, which means slightly less energy and wind resistance but noticeably less recoil impulse. It's a solid middle ground if you're splitting time between target shooting and predator hunting without needing maximum downrange power.
Can I reload the brass from Dirtnap ammunition?
Yes, .22 Creedmoor brass can be reloaded multiple times, though you'll want to check case condition between loadings. Fierce uses quality brass in their factory loads, so salvaging it for reloading makes economic sense if you plan to shoot volume.
Is the 77-grain Dirtnap suitable for hunting?
The 77-grain Nosler bullet is primarily designed as a match projectile rather than a hunting bullet. For predator hunting or field work, consider stepping up to a Dirtnap load with an expanding bullet designed for terminal performance. Match-grade bullets prioritize consistency and precision, not expansion.
