A properly tuned sniper rifle, with a 450fps spring, is not difficult to pull. Even the 500fps spring is easy. The spring that shot 530+ on 36's was tough!
what FPS are you guys shooting at? Since you're running gas, it won't be recognized as being able to shoot as a BA at level 2 if you are qualified which neither of you are currently so the max possibly allowable would be 450fps and some fields at 400fps.
If the field allows you to run hot then I know a lot of people would veto it before the start of a game.
