I have had a .17HMR since they came back out a few years ago. Just a bit of useless info, they tried to introduce the round in 1979 and it did not take. Anyways, I have a Savage 93R and love it. No reason to get a heavy barrel in this caliber, the sporter barrels are plenty stiff. You just have to understand the capabilities of this little pea, if you do and abide by them you will have great fun. The round is in my opinion the perfect combination of rate of twist, velocity, caliber, and bullet weight. Superbly accurate! I have shot pigeons at 150 yards seemingly w/o effort. This was off a steady rest of course. Ground squirrels at over 100 yards, and most were head shots. I have a 3-8 power scope on it. I would recommed getting at least a 3-9 power if you want to reach out and touch stuff. I can say this, the .22mag does kill coon better than the .17HMR, but the .17HMR did suffice. This caliber is also not all that friendly to squirrels. I once shot one head on, the round blew one front leg clean off and absolutely mangled the other. I shoot 17gr. V-Max. Perhaps the 20gr bullets might be a bit more meat friendly, but then you are giving up some flat trajectory. I would not shoot a coyote with this round.
