Looking through my most recent AyA catalogue (2010) I note that at that time they had a USD41 surcharge for steel proofing.

Steel proofing may be standard now but I imagine that the proof is for steel shot loaded to CIP standards, not SAAMI

Be very careful with this. Here is the proof mark for guns that have been proofed for steel shot:



If you dont see that mark on the barrel flats, then the gun is not proofed for steel shot.
