360 is pretty hot. The claws will dent at 360 but, for me, I really don't care and the fish don't either. The claw is pretty thin before it tapers back out and it could be hardening in the thin part, I guess. I've never had much trouble with this mold but you are shooting it differently with the tin can lam. Thinking about this a little more, that part of the claw is thin enough, you may need to just laminate the body and let the claw fill with the second color. What some folks do also is just do a claw color. You know, shoot the bait with the color you want the claw to be and then cut the claws off, put them back in the mold, then shoot the main color. It makes a nice bait too. Here's a pic of one I've done. Bob makes a claw mold for it too.
