Looking for the best round for 2 different ARs. One with a 1:9 twist. The other with a 1:7 twist.

What grain should I get that will fire great in both rifles? And what round in particular?

Most .223 varmint rounds whether ballistic tip or soft point are 55gr. Hornady makes a good consistant round. I still have some Coyotee 55gr. sp , These were loaded into LC surplus Brass. They did a great job.

I'm using Hornady 53 grain Superformance V-max. Great groups and devastating terminal ballistics.

Do you want less pelt damage or are you simply trying to put them down as humanly as possible?
If you want less pelt damage there is two schools of thought.
1. Use FMJ through the lungs and they will not go far. Small hole in and out.
2. Use a light fragile bullet which will cause an internal wound cavity and not exit.
If you don't care about the pelt I would use what ever 50 to 55 gr SP that shoots accurately in the rifle of your choice.

I guess I'm more worried about bullet stability in the 1:7 twist (my rifle). I've heard that 55gr is as low as I should shoot.

The 1:7 is a fast twist (one turn in every 7 inches vs the slower one turn in 9 inches). It should be able to stabilize a heavier bullet, but it's kind of academic, since a 55 grain soft point should be fine for coyote.

You have to shoot to see what your gun likes, 60 Vmax might work for both rifles.
Are you hand loading? I have had good accuracy from 52 gr Amax as well.

All bullets have been hard to find, I did see some 40 & 50 gr Nosler bt the other day at Cabela's.
