I'm not sure that anyone has the answer to your question. If your limbs have already experienced a dry-fire and survived, they may not survive the next shot, or the next dry-fire, or then again, they may out-live you. Who knows? I would say that your long 32" draw will probably not do much to extend their life.
I've dry fired a 1966 Bear Tamerlane twice and it's still going strong. I draw 32.5" and the #[email protected] is #[email protected] for me. Broken nocks both times in sub zero temps were the reason. How many times a limb can survive it varies by how well they are glued up I suppose.
