AR15RDY Report post Posted February 28, 2016 I'm going to try a 55 and 60 grain bullet. I usually use 55. I have a box of 40 grain I've never tried yet. I'm glad I posted this question because everyone has been very helpful. Share this post Link to post Share on other sites

I'm glad I posted this question because everyone has been very helpful. i sighted my gun at 100 for some bullets i dont have any more and killed 2 coyotes with completely different grains, one from far. so its flat enough i just keep rocking it lol Share this post Link to post Share on other sites
lancetkenyon Report post Posted February 28, 2016 1 in 9" twist is good to the 69-70 grain projectile weight range. My AR is a 1 in 9", and shoots the 69 SMK into 1/4" groups. Share this post Link to post Share on other sites

lancetkenyon Report post Posted February 29, 2016 I have my .223 dead nuts at 200. With a Zero of 200 I can just put the crosshairs on a coyote from 0-300 and hit it. What bullet and velocity are you shooting? I might need to do some more load work. Both my 50 V-max at 3400 and my 69 SMK @ 3033 both have 7"+ of drop at 300 with a dead zero at 200. If I were to hold center mass of coyote at 300, I would be missing. Share this post Link to post Share on other sites

lancetkenyon Report post Posted February 29, 2016 I did that with my .300RUM. Worked OK on some coyotes last elk season.... 1 Share this post Link to post Share on other sites

Slightly off topic, but what ballistic app do you use? i use the "shooter" app. im not no long range guy but its worked pretty good for me. 2 Share this post Link to post Share on other sites
jgraffaz Report post Posted March 4, 2016 I use 55gr bullets and zero at 75 yards. Looking at a drop chart is only 2 inches height or low all the way from 0 to 250yards 1 Share this post Link to post Share on other sites
lionhunter Report post Posted March 27, 2016 I have all my .223 's on at 100. 90% of the game I have called in over the years is shot inside 100 yards. If one hangs up further than 250 you will need to range to figure out the shot anyway. With that being said, the post in both my Ar's his perfect at 300. Good luck Ps. Pick a single bullet that shots well and performs on the hit and quit changing ammo Whitey Share this post Link to post Share on other sites
