I've read a lot about the fed HW turkey loads in #7's having good penetration at 40 yards... so I just ordered a box of 5... I plan to shoot them at 40 and 50 yards and compare penetration with the lead #5's at the same distance... Ill be sure to post results as soon as the weather breaks hopefully by middle of next month... if they pattern good and penetration is good I may think about them in my 12ga guns also... But that remains to be seen
