I agree with the above saying that the SVT will chew your brass up, my friend shoots an SVT but only feeds it surplus. He loads for his mosins as do I for my 91/30.
I got a Sierra manual that has lots of good info, for myself, IMR 3031 works great with 150 gr PRVI FMJ's. I also had luck with IMR 3031 and 150 Hot cor SP's.
