    dud, I happen to have 2 of them. Both are blown out to a 40degree shoulder with .294 necks. The only data that I know for a fact is available is all either h870, h570 or x283 data. However none of those powders exsits anymore. You could replace h870 with wc872. In mine the data is the same between the 2. I have tried retumbo but the results were not that great i used 73-76gr with 140's and 142's. Hope this helps.

    Check that H-570 carefully as I remember certain lots going bad fifteen years ago.
