It would be a LOT easier to shoot centerfire silhouette than highpower any day.
Shot with a few highpower guys. Their take was the opposite.
You shoot standing at 200. Everything else is prone with a jacket,glove and a sling.
Lets see some of your 500 meter STANDING TARGETS. UNSUPPORTED.
Highpower has 10 minutes to shoot the long line. Silhouette has 2 1/2 minutes. BIG DIFFERENCE
