Custom made 50cal rifle

[JBird]

Looks sweet. Is that a custom action from scratch or pre-built?

Wasn't this rifle intended to set/break a .50cal record for group size?

Custom action, built by Klaus Horstkamp at State Arms.

Yes, the record was the idea behind it. Klause built 25 rnds. specilaly for this gun and wrote down how much powder to use with them. I'm new to the long range stuff so I'v been learning as I go. Its 17 year old technology so what was the best back then is prob. no big deal now days.

The stock is powder coated

Nice, I originally thought aluminum, but realized that couldn't be right with the 150lb number, lol.
