Here's a post i made elsewhere:
Seems that a lot of people think of the HMR as being the only .17 Caliber out there and it seems to get a lot of confusion going. .17 HMR's are not a good coyote round. Many have even claimed that they're not adequate for fox either. I DO NOT suggest using a .17 HMR for prdeator hunting no matter what you've heard.
Just to clarify a few things. First, the .17 HMR is not the only .17 cal out there. There's actually quite a few. Most .17 caliber predator hunters nowdays use the .17 Rem. Although the .17 Predator and .17 Javelina have quite a following too. If you haven't seen "Winter Magic" yet, buy it. Most of the dogs on that video are shot with a .17 Javelina and a few with a .19 Here's a few links:

Look at the .17 Predator video here....30 dogs with a .17:

So...there's proof that some .17's are good coyote killing guns. If you can shoot a .17 caliber with a 25-30 gr. bullet pushing 3,500-4,000 fps....you can kill a lot of dogs. The good thing is, it puts a pin hole in them with no exit wound...97+% of the time. Too many people way overgun themselves then there's a few that under gun themselves for coyotes. Good thing is, you get the same results with the same rifles with cats and fox too. Hit a fox with a .22-250 and you'll walk up to a two pieces of a fox more times than not. Hit a fox with a .17 Rem and 97% of the time you'll walk up to a fox and have to search for any holes.
The .17 Rem seems to be the most popular .17 caliber for K9's. It's been around since 1971 and has had a great following. Factory loads can still be had, but most hand load them with 24.5 gr. of IMR 4320 and a 25 gr. Berger Match Target bullet. This seems to be the best combination. It enters the dog and turns the organs in the chest cavity to jello...with no exit hole. The .17 and .17 Predator are quite similar in velocity and downrange performance. They shoot the same bullets too, obviously. On top of reloading the Beger's, the Wood Chuck Den now offers .17 bullets called Golds. They are also offering a new boat tail bullet that'll likely buck the wind a ton better for really long range shooting a prarie dogs and chucks.
Here's some good reading on the .17 Rem:

Remember, we are hunting in MI and almost never shoot at a dog over 300 yards....harly ever shoot at a dog over 200 yards for that matter and if you can't get them within 150 yards, you should probably take up another hobby. We're not in the praries of the Dakotas, so we don't need to be shooting at a dog in the next section. That being said, you don't need a hide busting .22-250, .243, 6mm, etc. Those guns are meant for prarie dogs, deer and antelope...not 30 lb coyotes....way overkill.
Go do some research for yourself and you'll see that most .17 Caliber Centerfires kill dogs DRT with minimal hide damage. You're gonna need a few fur strtchers too, so go to the F&T link at the top of the page and get yourself a few wooden stretchers, push pins, combs and brushes....and start making a few bucks off the dogs you shoot. Don't bother picking up any thread and needles, you won't need it with a .17 centerfire.
Good Luck!
P.S. Just to let you know, a .17 HMR is about the size of a .22 mag, give or take...other than the bullet. The .17 Rem is similar in size to the .223. It was actually based off of the .222 which was a necked down .223 case. Therefore, it's safe to say that the .17 Rem is based off the .223 case, just necked down and shoulder reduced to a .17 caliber. This should give people a better perspective of the case differences. The .17 Rem has very little recoil, but packs a powerful punch.
Also, keep an eye on the .17 Remington Fireball (FB) in the future too and do some research on it. It was introduced by Remington in 2007. It may be a pretty good round, but not much has been said about it. I'm wondering if it'll even stick around that long. I have a good feeling that Remington will drop it and start making .17 Rem's again....which they stopped in 2007. CZ and a few other small manufactuers still make the .17 Rem. A lot of guys are rebarreling their guns to a .17 Rem now which costs about $175-$350...so there are options out there. Many guys have had the same gun for over 30 years, they just rebarrel them after about 4,000 rounds. SuperSeal on here could give more info about that and hopefully he'll post some pics. Oh, and some are even building a .17 Rem on a AR-15 platform too. A lot of guys out west are going this route.
