There was a recent article in Guns and Ammo on match grade .22LR. They used an Anschutz rifle and several different brands of ammo. As I read the article, I was thinking this is good information, but completely useless to what I suppose is the majority of shooters who will never own a match grade .22 rifle, and will never pay the $10 to $20 for a box of ammo.
I took my 10/22 with a old (found in a box in a house I bought) Bushnell 3-9 Sportview scope to the local indoor range for some testing of my own. With the scope set to 4 power and using off the shelf from the local wally world bulk pack ammo. The two contenders I had with me were Federal "Target Grade Performance" 325 round bulk pack, and Remington "Golden Bullet" 225 round bulk pack. I can't remember exactly what I paid for the ammo but I don't think the per round price is much different. The Federal is a solid lead 40 grain bullet @1200 FPS advertised and the Remington used a 36 grain hollow point @ 1280 FPS advertised. I don't have a chronograph to see how close they were. The indoor range has a 75' maximum distance to shoot at, so I ran the target out to 75'.
The Remington ammo grouped at 2" for 10 shots, while the Federal ammo grouped at .75" for the same 10 shot group. The Federal group was mostly one ragged hole with a couple shots that opened it up to the 3/4 inch. I don't claim to be any kind of marksman, so the group discrepancy could be totally my fault, but I don't think that is the case. At 75' on a solid bench rest and a 4 power scope it is fairly easy even for a old eyed guy to see the target.
I also found that what I thought was a dirty magazine problem in my Ruger 22/45 pistol was ammo related. I could not get more than a shot or two of the Remington to go through it without a jam, but the Federal fed just fine without a problem. I have been buying any 22 ammo as I found it, but will be a bit more selective in the future. This is not a bash of the Remington ammo, just an observation that my guns don't like it as well as other brands. The 22/45 has fed other brands, including hollow points without a hitch. The 10/22 don't seem to care what type of ammo it eats, and other 22 bolt and single shot guns I have will digest anything I stuff in them, but this is the first time I had ever shot anything side by side to see if one was better than the other as far as accuracy (and function) went.
Next up for testing will be my grandsons Rossi single shot rifle and an old Glenfield model 20.
