221 Remington Fireball

The following data was developed in a custom rifle, built on the Sako S491 action. We installed a stainless steel barrel from Dan Lilja, finishing it off at 26". A B&L 6-24X scope was installed in Leupold mounts, and a McMillan synthetic stock put the final touch on it.

We used Remington brass, and the Federal 205M primers throughout all our tests. All bullets were molly coated, and all groups were 5 shots at 100 yards.
