I've been wanting to try the CCI Copper-22 (21gr) simply to experience the velocity and accuracy at targets less than 50 meters. But either the price or shipping was a bit much. Today I found some at Buds for 7.58 per 50 count box. I was initially doing two boxes. Shipping was 10.00 insured or 9.00 uninsured. For the heck of it I changed the quantity to 4 boxes and shipping remained the same. I took the 4. A couple of places were 20-30 cents cheaper per box but shipping was more. Posting this for anyone who is interested. Having done a bit of researching I found 2-3 folks who chronographed the rounds closed to 2000 than the advertised 1850 fps. Probably bit slower from a barrel under 18-20 inches. but it should be proportional. CCI COPPER-22 22LR 21GR 50/5000 $7.58
