The Nosler M21 in .33 NOSLER is a bolt-action rifle built around Nosler's own cartridge, which was designed from the start to push .338-caliber bullets hard from a standard-length action. At 7.10 lbs and 44.5" overall, it balances well without being unwieldy in the field.

Detailed Features 

Barrel 

The 24" barrel has a recessed crown to protect the muzzle from damage and a threaded muzzle for suppressor or muzzle device attachment (1/2-28 or 5/8-24 tpi). A knurled thread protector is included. 
 

Trigger 

The TriggerTech Field trigger uses frictionless release technology to minimize pull-weight variation. Shooters who have used it consistently report a clean, predictable break that holds up across temperature extremes. 
 

Stock and Action 

The all-weather epoxy stock handles moisture and rough field conditions without warping. The stainless steel self-indexing recoil lug keeps the action bedded consistently, which matters for repeatable accuracy over time. 
 

Usage 

 
The .33 NOSLER cartridge is suited to large North American game where you need a flat-shooting, hard-hitting round without going to a magnum-length action. The 3+1 capacity is typical for rifles in this class. This is a hunting rifle first — the TriggerTech trigger and quality barrel construction make it accurate, but the 7.10 lb weight and all-weather stock put it firmly in the field category.

Users who shoot the Nosler M21 in .33 NOSLER tend to focus on a few consistent themes.

Accuracy and performance get the most praise. The .33 NOSLER cartridge shoots flat and hits hard at distance, and the TriggerTech trigger earns specific compliments for its smooth, adjustable pull. Build quality is well-regarded overall — the materials feel solid and the fit is tight out of the box.

The ergonomics are comfortable for most shooters, with the stock geometry working well in a variety of positions. The all-weather construction means the rifle doesn't need to be babied in the field.

The price is the main point of friction. The M21 sits at the upper end of factory bolt-gun pricing, and some buyers question whether the premium is justified compared to other options at similar price points. Nosler's customer service draws mixed reviews — some report straightforward, helpful interactions; others describe slow response times or difficulty getting warranty issues resolved.

The overall picture is a well-made, accurate hunting rifle that performs as advertised. Buyers who go in knowing the price and the caliber's purpose tend to be satisfied.
