Just getting into CAS and was thinking B-western as well.
How bout the Henry Big Boy? They have a model that is SASS approved...
as a shooter the Big Boy is just fine , with very good/excellent manufacture support...
as a CAS gun though, to much mechanical to over come to cycle quickly, They see use, but not by serious SASS shooters.
Think Toyota Venza (crossover) as a Prerunner
nice ride, just not the best platform...
Go with the Marlin 94, drop in the Palo Verde Marlin Spring Kit $22.00 , and a 1 piece Firing pin about $30 and you will transform the gun.
