These are some pretty large pills and glad to see he is offering some!

 The 305's exceeded the 1325 FPS rating!

Ruger Redhawk 7.5" 1342, 1376, 1353. Average = 1357 FPS/ 1247 LBS

I also ran the 245's for a second time out of my latest shipment. These are falling short of the 1450 FPS box rating but still a great target round.

Ruger Redhawk 7.5" 1398, 1400, 1385, 1409. Average = 1398 FPS/ 1063 LBS

Those 305's were some heavy hammers!

I hope Kevin adds a 330 or 340 at some point. His 305's sold out!
