I am debating on which of the two calibers to use as my main rifle. I do not reload right now and i do not care about fur. I just purchased a foxpro fusion and I am going to start calling some coyotes pretty soon. I will be hunting wide open farm ground with thick tree lines and anywhere from 10 acre to 150 acre patches of woods surrounded by flat farm ground in NE Arkansas. I will do some hunting in the hills occasionally as well but mainly flat open country. I have an Athlon Ares BTR 2.5-15 on my tikka T3X Lite 6.5 creedmoor right now, the Tikka is a sweet gun but shooting 143 ELD-X I find it pretty hard to try and stay on target during the shot. I have a Howa mini action 223 that is super smooth and is a great shooter, I can watch my shots hit the target all day with this little gun. But with all of my research I am thinking I will want the knockdown power of the 6.5. So here we are. I am considering getting rid of the creedmoor as I am not a competition shooter and wont be anytime soon. I have no where to practice out to 1000 like the caliber is capable of. So I am considering the 6.5 grendel in the howa mini action from brownells and putting it in a boyds thumbhole varmint stock. I love how short and compact the mini action is with the heavy barrel. So lets hear the opinions from more experienced coyote hunters. It gets windy at times in this flat open country and I want to be able to knock one down at 500 yards if I need to because I can practice to that far and get comfortable with that range.
