[QUOTE="J E Custom, post: 1257158, member: 2736"] Retumbo is one of those powders that can go critical with just .02 tenths of a grain increase. There are a few more powders that have that characteristic and even though you have a good load any change can put you over the top. Some powders are very linear and each increase will produce a linear increase in velocity. Retumbo is a great powder and seems to produce the best velocity, but that comes with a price and you have to watch the pressures closely. I am surprised that the pressure went up in very cold weather, but stranger things have happened with this small group of powders. If you want to use Retumbo, you may have to back off a little more or back off the lands a little more. (If you are shooting against the lands pressure will be erratic with some powders).
