I just checked underwood's site, no +p 40SW listed. Unfortunately buffalo bore is listing 40 +P and 44 mag +p+. In their information they state they are using - blah-blah-blah powder which give them "Higher velocity" with "lower pressure"???? Though this will anger some, I think they should learn the meaning of terms before using them. Too bad that a respected company will use total BS. Higher velocity with standard pressure- great sign me up, but when you list something as +P+,+P then state that it is "lower" pressure you are showing your ignorance. I guess they can also put 15 lbs of lead into a 10 lb box. Be Safe
