Just wondering if any of you have shot The Guigley Ford Q520? They are a round specific first focal plane school with at retical according to your bullet weight speed and BC Bullet coefficiency. I’ve bought two one for my 300 RUM and one for my RPR 6.5 Creedmoor. Both scope are still in shipping. The RUM I won’t be able to shoot until after my Rotator Cuff surgery.
