The rule is retarded in most area's because I've never seen at least one guy NOT abuse it and just fire off rounds at 470fps as fast as they can squeeze the trigger lol
So in Mb and some other places, we have full and semi at 420fps, and bolt action only is limited to 470fps
There was some speculation of bringing the semi-auto limit back to 470 and I straight up told everyone if we're doing 470fps with 50ft MED, I'm modding my PTW to semi only, jacking it up to 470fps and using .36s. And that pretty well ended the movement lol
Problem is most people think the extra fps magically gives you more range, but you NEED to use heavier ammo to get the range. Amos and I built the exact same VSR-10, he had a longer barrel at 470fps and I had a shorter barrel at 430fps and both using .30s I actually had better accuracy at less fps.
