After several months of searching to no avail, I just found Retumbo in stock at 3rd Generation Shooting Supply. I have never ordered from them before, but do remember reading a recent thread where most folks indicated they were on the up and up. A few minutes ago they were showing 68 of the 1 pounders in stock, but sadly only one of the 8 pounders (now zero because I just ordered it). Anyway, I hope someone can use the info.
