.025? That's smaller than 1/32" (it's actually 1/40", or 0.635mm, if that's even a real measurement)... did you mean .25 (1/4") or .125 (1/8")? Those would be significantly larger differences.
If it's truly a .025" difference, I doubt nearly a half millimeter will affect much, even with 45° sights, under 100 yards.
