The Speer 130 gn is a very solid performer (the Aussies use heaps of them for "station ammo" that has to deal with roos to bush bulls - so I was reliably informed by a Queensland mate last night). I shot a lot of game (not many deer it has to be said) with them in the early 80's when all I had was a 308. Just so happens that I have a box of them again now. 52 or 53 gns of W748 would get you over 2800 fps from your 14"
With your Speer 150's you'd get 2600 fps - still a very effective load to 300M !!
