Yes they doI believe Wac'em makes an 85 gr. ???
You said it. And lifetime no questions asked warranty (shoot it into a rock and send it in for a new one if you want), as well as being very easy to re-tune. I've been hammering on a couple practice heads for awhile now and have not had to re-tune them for a looong time, until recently. Quick and easy and fly like new.Have tried many different heads, from fixed, replaceable, to mechanicals and always come back to my Magnus Stingers. They have never let me down if I do my job. Best part I can re-sharpen them easily.
