Welcome to CGN! I don't want to make any assumptions about your shooting experiences thus far, but based on your questions...I'd urge you "walk before you run", and consider starting with a bolt action .22 of some description. Look up a Norinco JW-25, it's a .22 replica of a WWII German rifle~might scratch the itch for you! Going from nothing, to an SVT-40 is a huge jump, and the noise/recoil/cleaning of a gun like that might be a little overwhelming for a new shooter. If you hope to hit your target with something like an SVT-40, you need the trigger time on sometime allot more tame if you ask me. The SVT-40s also have muzzle brakes that GREATLY increase the noise level for you, and surrounding shooters. Some serious hearing protection req.
Just a thought... Take a poke around the rimfire section on here, lots of enthusiasts, discussions on various guns, pros/cons, etc.
