Used it recently in both .243 and .270 Win. Worked fine in both, 2 different bullet weights in both. I picked some up when it's best ability was availability, and will continue to use it when it's a fit. It's a bit expensive, but that wasn't so much of an issue when other powders were not available. I've got a few lbs on the shelf, but I'm not rushing out to buy an 8 lb jug.
