Yeah and when I called a few places last spring, was told they can not get them anymore, Summit, Manici. I was on the phone for 15 mins while summit was checking for ANY .040. Only cast and hyper's they could get
Trw joined the bankrupt, out of buiness party
Good luck, maybe U have better luck than me. Manici was sure they don't make them anymore, maybe Ebay come through for U.
Those old trw are heavy thou, @ 6,000 it be like the hypers turning 6,500. It live either way. I wanted trw at first also.
