Yes, as Al said, n130 has been around and used for a long while now but h4198 was available and it's just what almost everyone used. For good reason mostly, as it's hard to beat but I think there are other powders that can and do give equal and sometimes better(or worse) results. Like so many things in this game, if it ain't broke, do what everyone is is doing. Lol! With h4198 being unobtainable, for the most part, we have greater numbers of shooters trying alternatives and having success doing so. Not that h4198 was ever broken but that there are untested powders and combinations that are giving equal results when we are forced to really wring everything out of other combinations, in numbers.LT 30 seems to be available quite often. I read a while back that it should work. I would like to see this tried in the 30br with the 118 class bullet.
TY Al.
