I've been hunting for 50 years and recently have been shooting long for me anyway. I have recently shot from 100,200,300,400,500,600,720 and last from 880 yards with a 52 year old Remington 700 in 7mm magnum.We load and shoot 22-250,270,308,30-06 and now 7mm Mag. basically using hunting rifles. I have a Sako S20 in 7 mm magnum on the way and now I am finding it hard to find a 20 MOA mount for it. I look forward to learning all I can from the forum.
