Sako 85. 20". Lapua brass, federal 215 and 140 Amax.
12-15mm. Has fired 5shots into 11mm before. . . . All precautions taken. Obviously.
As a side note and of some interest was the successful use of Superformance Powder in the .260Rem. Others were hitting pressure early with 2209 while velocity were too low.
