In the second round of ammunition testing I wanted to do a better accuracy test, a slow fire squeeze 'em off just to see if there was any big differences. I also wanted to document as much data as I could on each type. Just because it's a lowly .22 does not mean one can't learn from it. I'm a fan of documenting my shooting, it's another facet of it that is not only rewarding in the simple methodology but can also teach me things. To that end I have a data book for each of my rifles. Storm Tactical in this case, though I also use other versions. A book allows you to learn the ins and outs of a rifle, makes range time more productive and over time you accumulate information that will make you a better shooter. Storm Tactical also offers down loads of multiple different types of targets, many of which are for use with their data books. Great combination.
I'm a bag man, I admit it. Over the years I've accumulated closets full of bags, in this range excursion I used my TIB from One Source Tactical to carry ammo, mags, data book and assorted other sundries. OST is a great group of people to deal with, over the years I've never had a so much as a hick up with their service or products.
Couple of images from the range, above the scope and through it. Shooting was done from 75 yards, prone using a bi-pod. Scope is a Leupold Vari-X II 3x9x49. The camera was a little far back from the scope and doesn't show an accurate portrayal of the image normally seen by the eye. It was cloudy and damp, wind was nominal out of the west at about 3 to 5 miles per hour, 48 degrees.
I started with CCI Stinger 40grs and an advertised muzzle velocity of 1640fps. There was one flyer in the group, the rest were pretty much dead on, tearing a single ragged hole. All groups were seven rounds each.
Next up was Winchesters Hyper Speed Hollow Points, 40grs at a stated muzzle velocity of 1435fps. This was a seven round group as well.
Winchester Varmint HE, 37gr segmented round with a stated velocity of 1435fps. The segmented bullets from both Winchester and CCI are basically 3 segments designed to separate on entry, creating 3 exit wounds. In the limited testing I've done so far this is bearing out, the rounds are absolutely devastating and create large exits. Not the round to use if you're looking to maximize meat take and or preserve the pelt. It's going to leave major damage on both counts. More on this in phase III of the testing. Four of the rounds were nearly same hole, 3 flyers, could have been me though.
CCI Segmented 32grs, muzzle velocity 1640fps. Not the tightest group but not bad either. This is basically the same thing as the Winchester Varmint HE, CCI claims theirs is roughly 200fps faster. I have my doubts though without a chronograph I can't confirm. I know I held in the same spot, I would have expected another 200fps to have resulted in impacts higher than the Winchester round, this did not happen, even though the Winchester rounds are heavier by 5grs.
CCI Segmented 40gr Subsonic. I really like subsonic ammunition, much quieter, so much so I can hear the bullet impact the target. It's much slower than all the other ammunition tests with a stated muzzle velocity at 1050fps. Knowing this in advance I held on the top black triangle of the main diamond. This resulted in impacts to the target between 3.5 and 3.75 inches below the point of aim. The group wasn't bad over all, three flyers.
