I shoot a Remington model 700, 7 mm rem mag, bedded and floated. Hand loaded with 69.5 gr Retumbo toped with a 160 gr Nosler Accubond. My optics are Leupold VX-ll 4-12, 50 mm with the m1 elevation turret from their custom shop. I'm a fairly low tech western high desert hunter so I just proof out my handloads in the field and print up a drop chart in 50 yard increments, laminate it and tape it to the left side of my butt stock with camo cloth tape.
