Recoil - - Gemtech Aurora Ii -

All loads were tested for ve­loc­ity us­ing both 16- and 9-inch bar­reled weapons. A Rem­ing­ton 700, equipped with a Night­force ATACR 4-16x42 and Si­lencerCo Omega was em­ployed as our longer ri­fle, and it was this combo that we also used for ac­cu­racy and gel test­ing. Five-shot groups were shot at 50, rather than 100, yards as we felt this was a re­al­is­tic dis­tance for subsonic use. The shorty gun was our bud­get hog ham­mer — a franken AR built on a Gibbz side charg­ing up­per and equipped with a Maxim De­fense PDW pis­tol brace. Note that all loads ex­cept the Fort Scott and Go­rilla of­fer­ings were su­per­sonic from the 16-inch bar­rel.

Ve­loc­ity read­ings were taken us­ing a Cald­well G2 chrono­graph, which has the use­ful abil­ity to store data on your phone via Blue­tooth. Chrono was set up 10 feet from the muz­zle, am­bi­ent temp was 69 de­grees at 2,100 feet el­e­va­tion, and gel test­ing was per­formed us­ing two, 16-inch Clear Bal­lis­tics gel blocks, placed end to end.
