Newbie questions....
I am setting up my 6.5CM with a 2.5-15x44 scope. The scope has a ballistic turret and am planning to set it up to shoot up to 500 yards once I finish develop a load for the rifle. A few questions I have so far are:
1. Is a scope level a necessity when I am NOT planning to shoot beyond 500~600 yards?
2. I am intrigued by Accuracy 1st scope level. Are any of you familiar with it? If so would you share some pros and cons?
When I plug in the BC for the BT set up, the bullet (Hornady ELD-X 143 gn) has G1 and G7 BC under MACH 2.25, 2.0, 1.75. Since I am calculating out to 500 yards, I am planning to use BCs under MACH 2.0 column.
3. Do I use G1 or G7 BC to calculate the trajectory? They are quite different....0.604 G1 vs. 0.303 G7 for the bullet.
Regards,
