Got my new Optima V2. Was curious about the 300 gr Aerolites. None of the stores around here carry them, just the 250s. Looking at the ballistics brochure on Powerbelts, it lists that the 300 gr aeros have almost 400+ lbs energy at 100 yards vs the 250s and the copper 295gr. Curious of opinions or experience with the 300gr aeros.
