Paul-

Speer never offered a pistol bullet, so I am guessing you meant the 130 grain Sierra SSPB. Anyway, the 120 grain BT works wonderfully in this cartridge, no matter if you are using a 10 or 14" pistol barrel or a rifle-length as I do. . I use it in the 7mm Bullberry and 7-30 Waters (both around 2650 fps) with results that have to be seen to be appreciated. Here are just a few of the results.

BTW, I've had best luck with Re-15, LVR and W748, but the Waters capacity/bore size works well with a number of propellants in the medium burn range.
