coyote; I hate to say you are wrong, but you are. the fastest 22 mag bullet travels at about 2100 fps, that I know of, the fastest clocked 17hmr, is almost 2700 fps now, through some top notch bbls. the b.c. of a 22 mag is about .107-.110
whereas, the 17 hmr is about .125. Because of this , a 17 hmr at 100 yds, is still going over 2000fps at 100 yds, whereas a 22mag has lost nearly HALF OF IT'S SPEED AT 100 YDS!!!! Your chart is also from 2005 , and is not that accurate.
A dude I kinda know, a friend of a friend, is a sherrif out in columbia or w. columbus , texas. Part of his job is to cull varmint animals. he does this with a 17 hmr primarily. He told me about 6 months ago, he had allready killed over 30 coyotes, all were one shot kills, and his longest shot was 160 yds.
chekc this chart, for trajectory, even though it is not energy, look at the trajectory diff, between the two at say , 200 yds. there is about an 11 inch diff in drop, this should give you a pretty good idea of the energy diff. it goes from 1.5 in at 125, to 3 in at 150 to 6 in at 175, to 11 in at 200yds, so trajectory is dropping off fast.

here is another experpted article; remember , the speed of the 17hmr is still a little slow;
"This chart includes the 22 Mag 33 gr V-Max with a 2000 fps muzzle velocity.
Velocity is an important factor in calculating kinetic energy, but so is bullet weight. We have already seen that the .17 HMR is by far the faster cartridge, but the .22 WMR shoots a far heavier bullet. Energy is important because it powers bullet expansion and penetration, and is a major factor in killing power.
Here is the energy of our comparison loads, in foot-pounds at the muzzle, 50 yards, 100 yards, 150 yards (when available), and 200 yards (when available):
* .17 HMR, 17 grain V-Max = ME 245 ft. lbs., 185 ft. lbs. at 50 yards, 136 ft. lbs. at 100 yards, 99 ft. lbs. at 150 yards, 72 ft. lbs. at 200 yards.
* .17 HMR, 20 grain XTP = ME 250 ft. lbs., 187 ft. lbs. at 50 yards, 137 ft. lbs. at 100 yards, 99 ft. lbs. at 150 yards, 72 ft. lbs. at 200 yards.
* .22 WMR, 30 grain TNT = ME 325 ft. lbs., 200 ft. lbs. at 50 yards, 120 ft. lbs. at 100 yards, 80 ft. lbs. at 150 yards.
* .22 WMR, 40 grain JHP = ME 324 ft. lbs., 230 ft. lbs. at 50 yards, 162 ft. lbs. at 100 yards.
Here we see a different story. The .22 WMR starts with about a 75 ft. lb. advantage in kinetic energy at the muzzle. At 50 yards the 40 grain .22 bullet is carrying about 45 more ft. lbs., and at 100 yards the 40 grain .22 bullet still has a 25 ft. lb. advantage over the .17 bullets. At 150 yards the .17 HMR has an energy advantage of about 20 ft. lbs. over the 30 grain .22 bullet, and we have no figures for the 40 grain bullet beyond 100 yards."
