I soaked these 540's up long ago, simply .. they were cheap. Noticeable, but I've never heard the Jeffery crack the sound barrier like these?Had both 500 Jeffery and 505 Gibbs. 500 J for me thanks. Shorter/Smaller action, and I've had no trouble getting 2250 fps out of a 22" barrel. All that said, they are both fine killers.
