510fps?!?!That's some serious air arrow power. My Air Saber doesn't come close to that. Neither does my crossbow (400 fps or so).Is it accurate in the 500s?
How does the fletching hold up driving that deep into the block?
Great idea Darrell, I have been using a cardboard tube stuffed with plastic grocery bags to catch slugs I test and want to keep pristine with riffling marks intact. The bags stop them in short distance, I will have to make something up with a bigger container like a feed bag etc. Thanks!
