I have 22LR ammo that is now over 20 years old from my late fathers stock supply. Some of it shoots well but I found in very cold weather some of the rounds were not very consistent.  This spring I have begun to shoot it off at the range and plink some metal plates at a distance. I will buy newer stock of brands that my rifle prefers. I have an old Marlin Glenfield Model 60 semi-auto that still shoots well for all its years. Fact is, it didn’t get shot much for target, only hunting and that was very irregular on squirrels. I have a new Savage rifle coming and want to test it with new ammo as well. The Marlin likes high velocity ammo and really likes CCI Velocitor for accuracy. I have just ordered more. It is a very accurate round for squirrels, snowshoe hares and varmints. At 50 yards my older Winchester High Velocity Ammo was shooting 2 inch groups at 50 yards below.

Good for Squirrels at say 25 yards to get better groups for a head shot so I have kept some.

But I remember that the CCI Velocitor shot even more accurately. So I shot a few also at 50 yards to confirm. Yup. Below all in less than 1 inch with a flyer. I just need to move the crosshairs a bit to the right. It not only delivers at extremely high energy but very accurate too.

I did take time to clean the barrel and clean and lube the action.

I will do a 100 yard test at some point.

Here are stats from CCI below.
