[QUOTE="davewilson, post: 215025, member: 4491"] William, first off welcome aboard, it's a great place to come visit but i gotta warn ya. it gets addicting! you've got everything you need to know.the only true and consistant way to tell pressure is a sticky bolt. when the brass starts flowing into the extractor hole, the pressure is probably in the 70K range. some brass takes a little more pressure than others, but a sticky bolt means you're about 2 or 3 gr of powder too much. simple as that. the biggest variable is usually the temperature. this is the hot time of year. most shoot their gun enough to know what is hot for what time of year.i realize this is a first time load for your gun.i usually compare a new powder with a powder a know in a couple of manuals and then start out conservatively. also i assume you don't have the bullets very close to the lands. that's not a good thing for a new load. personally i wouldn't use rl powder, it seems to be very inconsistant these days. the bench crowd has all but thrown it to the dogs. hopefully someone with 300wsm experience will jump in help out. bottom line, 63 to 66 would be the range of powder for a ladder with your gun.
