Re: 6.5 x 284 slow bullet ?
Can you shoot for drop? If you do and don't hav the program to run the numbers several of us do. We just need elevation, baro, and temp. If you zero at 200 and shoot 500 without making adjustments your bullet will drop x inches. This is the number we need to figure out speed. With 57.5 retumbo you should see 34-36 inches of drop, FOR EXAMPLE. Without the known conditions this is just a range. I am right around 33.8 to 34.3 for the area I am hunting right now.
