Stock bending experiences ?

[C grade]

I have has 4-5 Parker's bent up and over, mostly D grade guns. I agree it is very wood specific. I had a D grade hammer split at the wrist in attempting to move the heal 1/2 inch. I have had three well respected men do the work and found the wood moved back about 25% in most cases.
I have found the American walnut the most difficult to move .

I sent Mike Orlen a 20-ga. Sterlingworth with a 14" LOP and 2 3/4" D@H with instructions to bend it up as much as he felt comfortable doing. It was returned having a 2 3/8" D@H. It did not revert back.

I also have a 12-ga. Trojan with a 14" LOP and 2 3/4" D@H. I had that one bent up to about 2 1/4", but it didn't hold, within a couple of days it reverted back to its original 2 3/4" drop.
