Re: 17hrm verses 22 mag@300yds.
I just bought a 17HMR last week. The rifle is a Savage bolt action with a heavy bull barrel. I paid $209.00 at the new Gander Mt in Middletown, N.Y. The little round/rifle is capable of sub m.o.a at 100yds. I had the oppertunity to try the CCI TNT hollow points and the Hornady V-max, both are just 17 grains. The V-max holding a slight edge over the TNT's in accuracy and terminal performance. The advertised veloctiy on the box of Hornady was 2550 fps. With a zero of 100 yards, I was hitting unbroken clay birds from the trap range set upright at 150 yards with little to no effort. The 17HMR is a great round and is alot of fun to shoot. It is in my opinion capable of shooting out to 300yds at balloons. The only problem with this round is the wind. It does not take much wind to drift the little 17 grain bullet off target. I hope this helps you. Good luck with the shoot. Please let me know how you make out.
