Looks like this one: 292 cast Lyman 457191 IMR IMR-4198 29.0 1366, is about as close to the Tex-X factory I can get and it doesn't look like he has to use TP for wading. The 10X rounds don't have any in them either as you can hear the powder when one shakes the brass. My rifle is a Uberti which is identical to the Cimarron and when I bought it, the manufaturer recommends the 10X loads which are of course a lot hotter than the original loadings. Of interes, Buffalo Arms loads closer to original specs with trimmed 45/70 brass right at 1280 fps. Thank you very much for the info. jorge
