I have a Predator Pursuit in 20", a coyote 16" as well as a new 6.8 upper A4.
The PP will do 1/2" with either good H/L or she really likes the Black Hills 52 gr OTM in a factory "refurb" round. The coyote is new but it will print at 3/4" consistantly with either black hills or h/l in 55 grain. the 'yote seems to like el cheapo 55 gr Remington FMJ pretty well and will shoot in the 1" block with that stuff.
RRA outperforms thier advertisments.
Have also been shooting a friends 6.8 coyote that I have been trying to get on the shoot til I own it program for the last year. I haven't got a lot of real world work on it yet. With Hornady 115 gr OTM, it shot right at 1" to 1 1/4" (two stage trigger seems a little heavier than the other two but it just maybe a lack of familiarity). He had worked up a couple of 115 gr sierre HPBT loads that 3 shot at 1". All of the work on it was with a fixed 4X scope.
The A4 is going to become a deer killer in the scrub. I want something that handles fast, hits hard, and points like your finger. I have the reloading dies ready and can't wait to work up a good deer load based on 6.8 coyote I have been shooting.
IF i recall correctly, they were using the Black Hills remans and maybe Lake City to do their 3 shot testing.
You can't go wrong with RRA. This is a small family owned company where the owners are right there at the shop. As mentioned above, own one, and you'll own more. I will have a LAR8 in 7mm-08 as well as the 6.5 Grendel when they finally confirm it exists!
Best of luck,
Ted
