Yesterday was the first day taking out the newly converted Savage 110 Rifle First 10 shots went down pipe with Handloads using ADG brass, H4350 powder and very very old 175gr sierra spitzer boat tails (Today's Sierra Game King). Velocities out the gate where just under 2900 FPS. Powder charge seemed mild, Hornady 10th edition list max charge with H4350 at 53.4gr. Rifle: Savage 110 Tactical Converted from 6.5 Creedmoor to 7mm SAUM Preferred Barrel Blanks 27" Medium Palma 1-8 Twist 5R Chromoly Preferred Barrel Blanks Big Bore brake Bedded and modified Factory Savage Stock SWFA 16x SS Scope Best group was the last 3 shots @ 54.2gr. Like most stick extruded powder, performance seems to come together when the powder capacity is near compressed. Overall I'm very impressed with the outright performance of this barrel from Preferred Barrel Blanks. I think this rifle is going to be a shooter!
