Stock material vibrations

[tim in tx]

here is a real life test on stock tracking

these tests represent real to life actual tracking of a benchrest rifle resting on bags under totally free recoil.i would like to see varmant al model this in as well if possible.and it represents the torque effect durring recoil,as well as any bounce.i have done many more test since this one on all kinds of stocks with different metal in them as well. and poi was noted as well. the brands of stock will not be told as i do not want to cause any problems for the manufacturers. tim in tx
