This issue has not come up in our game, but the issue that I'm having is about the new Sniper rules from the APG and the 30ft limit in the helms description.
Does the new Sniper rules allow you to increase that 30ft range for on the helmet or no? Since this was specifically created to allow rogues to use their sneak attack at range?
Deadly Range (Ex): At 3rd level, a sniper increases the range at which she can apply her sneak attack damage by 10 feet. This range increases by 10 feet for every 3 levels after 3rd. This ability replaces trap sense.
Helm's ability : In addition, once per day the helm may be called upon to enhance any ranged attack made by the wearer to make an insightful shot. Activating this ability is a free action, and once activated, your next ranged attack against a target within 30 feet is made as if that target were flat-footed against you—this allows a rogue to gain the benefit of sneak attack with this shot.
