So here's how it went:
I found a lot of different apps and PC programs to run my phone from my PC. They all required actions from the phone. If not downloading an app, then at least some settings that needed changing in order for me to get access via the USB cable. This wouldn't do.
I solved it by having to phones of the same size next to each other, both with strelok installed, and "flying blind" to make Strelok export rifles.srl from the old phone. I then used the USB cables normal function to get the file and put it in the correct folder on the new phone.
I don't have a Labradar, and there's a competition this weekend...
Other possible ways to do it:
1) keep backups outside of your phone
2) Enable USB debugging mode now, it is required for remote controlling your phone via USB.
3) There are ways of giving input to the phone without the screen. In some situations it might be easier to do it with a keyboard.
4) Keep your dope on laminated paper cards.
