Most of my loading is trying to match the 150grain surplus ammo. I use .312 Hornady 150gr SP with about 53 grains of IMR 4350 for about 2600 fps. I'm still adjusting the load, and although it works really well I'm trying to find the best average for all my guns that shoot this cartridge.
Just some added info on Russian 7.62 rifles, including the SVT40: I have some rifles with larger bores, but they are not shot out, simply machined bigger but still have strong rifling. If someone is concerned they have a rifle that is shot out, just slug the first 6 or 8 inches from the chamber and push it back out the way it came in. THis slug measurement will differ from the slug pushed through the entire barrel.
Having said all this, some of the heavier rounds that are sold by places like Westrifle such as the 203gr soft point from LVE shoots extremely well, however a different gas adjustment if using svt40. I've tried the 203gr soft points in MFS with pretty good results but a bit behind the LVE from my shooting/groupings. I've used both for hunting and can bang flop a deer on just about every second shot.
