I've got a MK. V. in 270 mag, and I'll dig up my loads for you (where ever I have them stashed). I'm just starting to do some work with RL 25, and taking a serious look at MAGPRO, but data is extremely sketchey. I did find some nice data over on the Accurate website. Forget the Hogdon's manual; it's a joke!
