welcome padwan,
RFs can be picky. So what will run out of mine fine, may make yours puke.
You are better off buying and trying what you can get your hand on and do some testing. If something is too expensive for you, then dont.
FWIW, many people had some issues with TB, where it leaded up their barrel. So, the first thing you may want to do is to check your barrel.
Also this is how i do things, but i just dont have autoloaders in RF, i have singles shots, BAs and LA and so forth, so if 1 type/brand of ammo wont work in one, then it will work in something else.
