Prosport & TX baffles

Over the years I have experimented with various harmonic barrel tuners with little to no sucess on a springer. My guess would be to much mechanical movement to actually help. In years gone by, Vortek made a slip on tuner that had very limited sucess on springers...on pcp..that is another story !! I wouldnt expect seeing any noticible change, unless your rifle is really bad to start, even then there are many other things to try first !! Just my two cents anyway....
