Nice article. Shame he did not have all the data on the heavier, 40 grain .22WMR a 150 yards.

The 40-grainer had the edge from somewhere below 100 yards compared to the 30-grainer ... despite starting out slower.

Velocity
.22 WMR, 30 grain TNT = MV 2200 fps, 1720 fps at 50 yards, 1340 fps at 100 yards, 1080 fps at 150 yards.
.22 WMR, 40 grain JHP = MV 1910 fps, 1610 fps at 50 yards, 1350 fps at 100 yards. [missing data]

Energy
.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. [data missing]

Trajectory
.22 WMR, 30 grain TNT = +0.8" at 50 yards, 0 at 100 yards, -5.8" at 150 yards.
.22 WMR, 40 grain JHP = +0.9" at 50 yards, 0 at 100 yards, -5.7" at 150 yards.

Good thread , living in Central I thought I should give the Wallaby shooting a go. I have shot 1000's of rabbits with the .22 and 17 HMR and really couldn't wish for a better Bunny combo for the style of shooting I do.
However I was or am worried I would be under gunned for Wallaby.
I have shot a few out the back of Rotorua with .22 and it was fine but it was close bush work with nothing over 40 mtrs , down here I am guessing it will be more open shooting.
I hate reloading so centrefire is out, is a 22 mag going to do the job out to the ranges down here ?

@viper in a word, no. Sure you'll kill some, but you'll wish u had more range. If u can use centrefire you'll have more fun. A 223 is ideal and cheap as to run on budget ammo.

Agreed - the wallabies around rotorua are Dama species - little fellows - some not much bigger than a large hare. In Waimate area the Bennett wallabies are alot bigger at up to 800mm tall and 15-25kg, and while a 22 mag may get you some if you shoot them in the engine room or head, a 223 or 243 will be much more assured for kills. 223 excellent unless you also want to pop some bigger animals at range eg pigs/deer - then the power and versatility of 243 would make it a good choice.
