Minimal perceived recoil and modest muzzle rise prevents flinching and enables rapid follow-up shots, respectively.

Primer: WSR
Case: Hornady
Case Trim-To Length: 1.355"

Notes: test rifle: T/C Encore with an 16" SSK Industries barrel outfitted with a like-brand sound suppressor and a Bushnell Elite 5-15X 40 mm riflescope; *average of five consecutive, five-shot groups at 100 yds.
