While Voodoo is a great action its a great repeater ,main feature being its replicating the centerfire feel as a trainer with same footprint and same format magazines ,by default not competitive with a single shot bolt guns.
Voodoo would be eaten alive by courrent firearms used in OL games , both in Biathlon and in 3P . I think people are overestimating the Voodoo accuracy , folks that never shot the guns they think it could run against.
Voodoo is courently a top dog in PRS type shooting where rifle accuracy is not the most important thing. In 3p single shoot guns are some of the most accurate Rimfires ever developed and without exception all feature extreme short lock times not seen on any US made action ither rimfre or centerfire , all feature vertical sear two stage triggers that make best Rem700 compatible triggers seem crude (both features very important to sling shooters.In Biathlon the straight pull Fortner action is without peer in terms of speed , feature similar short locktimes and 2 stage vertical sear triggers and its accuracy is optimised for -20°C
In US BR scene ,single shot rifles using actions like Turbo,2500x are next level accurate over Voodoo , as far as i can tell Voodoo run Bartlein Barrels . But due to slow lock time and trigger none are that competitive in slingshooting where Euro actions dominate.
Rimfire BR or 3P everyone runs tapper lapped button rifled barrels from Muller, Shillen ,Broughton not many top shooters willing to run a Cut Rifled barrel for big comps. Rimfire at present is just not a cut rifled barrel game also no one would eave try runing a barrel shorter than 23' as there is a general consesus that longer barrels work better most are 25-27' long , in sling shootin short barrel fad run its course 2 decades ago but people found out that the gain in 'barrel time'(obviously important to slingshooters) is more than offset by short barrels being very fussy in regards to ammo.
