Here is a rough formula for figuring the sewing time required for a Coyote shot with different types of rifles: Multiply the bullet diameter by the bullet weight in Grains times the muzzel velocity in thousands of feet per second and divide it by the range in yards. So a 30-06 with a 150gr bullet doing 3000fps at 100 yards will require about 1.35 hours of sewing time. A 17 remington doing 4000fps with a 22gr bullet will require about .15 hours of sewing, and a 40gr .223 will take about .3 hours to fix up. Bullet diameter (.30) times weight (150) time velocity in thousands (3) divided by distance in yards (100) equals 1.35 (hours of sewing time) Estimate only, your results may vary. Larry
