CCI SV versus Hornardy Varmint Express 40gn /1070 LR
The gunshops have been stocking Hornardy 22 LR ammo for a while now and given the "on the box" spec was the same as the old standby of CCI "Standard Velocity" I was curious to see how it performed.
Testing at 100M will really show what 22 ammo will do, as long as conditions are reasonable, and here today we had nice bright light, about 5 or 6 degrees and a puffy wee wind of 3-8 km/h at about 90/100 degrees.
Using a superbly accurate CZ 457 20" lightweight barrel (man I lucked in on this rifle, got the last one off the shelf, and it will hang with the big $ boys) I shot 10 "fouling" shots at the gongs, then 3 groups each of 10 shots. After much head scratching I'm using the 3x10 protocol as it gives a very sound statistical result.
The puffy little wind kept giving me wind effected shots, so I measured the groups "vertical" only - you can see this in the test group fired with known ammo, in this case Eley Team, this rifle will regularly do 0.6 to 0.8 groups with the batch I have - wind has strung it out to over an inch of horizontal!

So in conclusion both ammos shoot to the same point of impact (I dialed 3 clicks left before shooting the Hornady) and really the groups are very similar, and I don't think there's much doubt that it's the "same" although you'd never know if the accuracy specification was identical.
