Regarding Merkels:
They come with an unlimited one year warranty.
Dude I know droped his 470, cracked the stock and they replaced for free.
Merkels will shoot Barnes X and TSX. I have shot nearly 500 in mine.
Merkels will regulate below spec velocities if you know why that is important.
Merkels come with a splintered forearm (thank God!)
Merkel sells the cheapest new 500NE
