Do the Federals key hole in the 147g?
Hoserack - I am sorry, I did not put you on 'ignore'. I just saw this while going back and looking at the pictures of primers from Chihuahua Tn's post.
To answer your question, I really do not remember 100 % if I put any Hryda Shoks on paper or not. I shoot steel about 100%.
If there is reason to believe so, then I will check it out.
Thanks
