Yep
Chopper .... the accuracy change on your shorty 14 might be due mainly to the weight of the muzzle accessory, aka optimising barrelHarmonics, rather than the Brake VS flash hider part of the equation.
PS: did you test the barrel for accuracy with nothing screwed on??
enquiring minds want to know!
LAZ 1
I did - no nada on barrel , bored out ar bird cage , and pws - PWS won. I thought the no nada would win because of concentric blast gas - but less gas blast won which was surprising because of the consistency of the bullets-- (not like cast lead .22 rim fire pills.)
A stiffy barrel [cause its shorter] is less susceptible to spahgetti whip anyways -
The boss concept works well with thin barrels and an adjustable (ala boss) PWS brake may extract even more accuracy to tune whip and bullet exit optimally, however I have also noticed accuracy improvement with a brake and standard length norc barrels as well as 10 inch AR barrels. (I have a 10 inch AR that shoots half inch at 200 yds with a PWS (ZERO WIND! - [a little gust gives fliers up to 2 inches away from group] )
By the way - u r right -- testing only works with the right ammo the gun has an appetite for - Hirtenberger is not bad but not as good as -
My fave ! The old mexican match or south american match - the bad stuff with the bullets replaced with match bullets that was all the rage with ORA and DCRA a few years ago.
I've built over a dozen rifles that all loved that stuff --
Down to my last few hundred rounds of it tho -
6 bucks a box of 20 - If only -----
OH ! ALSO ! --No copper in the bore ! I found that a copper free tuned norc shoots under an inch and copper coated bores shoot 2 inches- JB and KG12 are my best friends --
