Some shooting with the 22 WRM

Last week we went to Cabelas in East Hartford and I picked up a chronograph for my birthday. Today I had some time to take it out and do some testing. The gun of choice was my ubiquitous TC Contender with a Super 14 22 WRM barrel attached to it. I have several types of ammunition for that caliber and I wanted to see what each type would actually do out of the Super 14" barrel.

The shooting session took place between 430 PM and 600PM. The temperature was 70 F with humidity at 54%. No wind was present and the elevation of the range was 400 feet above sea level. All of the ammunition tested was shot out of a 14 inch TC Contender barrel. Each session consisted of ten shots with averages calculated on those ten shots.

1. CCI Maxi Mag ammunition. 40 grain hollow point load.

High Velocity=1867
Low Velocity=1821
Average= 1841

2. Remington V-Max 33 grain ( This ammunition is about ten years old and bought out in North Dakota on a trip)

High Velocity=2027
Low Velocity=1962
Average= 1994.4

3. Hornady Critical Defense 45 grain FTX

High Velocity=1805
Low Velocity=1742
Average= 1783

4. Speer Gold Dot Short barrel 40 grain GDHP

High Velocity=1916
Low Velocity=1848
Average= 1880

5. Speer 30 grain TNT hollow point by Federal. This was bought out West and is 10 years old.

High Velocity=2300
Low Velocity=2118
Average= 2179

6. Winchester Super X 40 grain JHP : This is advertized as doing 1910 fps on the box.

High Velocity=1841
Low Velocity=1731
Average= 1809.

7. Winchester 45 grain Dynapoint

High Velocity=1598
Low Velocity=1478
Average= 1528.2

8. Winchester Supreme 33 grain JHP.

High Velocity=2045
Low Velocity=2005
Average= 2027.5

I did notice some things while shooting. The position of the gun would have an effect on the recorded velocity. Some of the differences in velocity were very large and I attribute this to that factor. I would like to do this again and construct some points on the rest so that the gun is in the same position at all times. This will ensure a greater amount of accuracy. As it stands for hunting varmints it appears that the Federal load with the 30 grain Speer TNT hollow point is the way to go. That first shot at 2300 fps really opened my eyes but I realize that it may be an anomaly. I do recall that it worked superbly on prairie dogs as well as rockchucks.

Hopefully I will have some time to do another session.
