History
Introduced in 2020 as the sixth member of Nosler's rebated-rim magnum family (.26, .27, .28, .30, .33 Nosler). The .27 Nosler targets hunters who want .277-caliber bullet performance at maximum velocity — filling the gap between .270 Winchester and the larger .28 Nosler. The 6.8 Western's 2021 introduction created direct competition; both cartridges use .277 bullets with higher BCs than traditional .270 Winchester loads. Nosler chambers their Model 21 and Model 48 rifles in .27 Nosler and produces proprietary ammunition. As with all Nosler magnums, the cartridge requires Nosler-branded or custom rifles.
