We developed the following loads in a Blaser R-93 rifle. It had a 24-inch barrel, and a Zeiss 3-12 scope in Blaser mounts. We used RWS brass and the Federal 210M primers throughout our tests. All groups are 3 shots at 100 yards.

The following data was developed in a custom rifle built on the Sako 75 action. It has a 25-inch stainless steel barrel, and we installed a Leupold 2.5-8 scope on it using Sako mounts.

All groups are 3 shots at 100 yards. We used RWS brass and the Federal 215 primers in all our loads. Loads with Hodgdon H 414 had very erratic velocity excursions. We could not get any more than 72 grains of H 4350 into the case, as this load was highly compressed.
