Just from what I've read elsewhere & a little guesswork, I'd say that that you could probably expect close to 2000fps with that load. However, you'll probably also find that it is not very accurate. Typically, the 150gr of powder does not burn completely in the barrel and ends up throwing the bullet off some as it leaves the barrel. 100gr of powder is more that enough for that light of a bullet - and it will be more accurate to boot!


"Every moving thing that liveth, I give unto you as meat" (Gen 9:3)

Trust God..........but keep your powder dry!
