Tuesday morning was a rather nice, warm, dead calm day. I decided to test out my 150g CT BT's at 800 yards for the first time since working up the load a little over a month ago. After only testing 3 loads I found what I thought would be good enough for antelope and deer hunting out to about 800 yards. The load is as follows, 150g CT BT, 105g of H-1000, Rem Case, Fed 215, OAL=3.660", 3650fps. First 3 shot group with this load was .295", Second group was .360". The rifle is a .300 RUM LSS with a trigger job down to 2 3/4 lbs. Other than that, rifle is completely out of the box. Scope is the newer Leupold VX2, 6-18, matte, fine duplex, target. After shooting the first shot to warm the barrel, I shot 3 more very carefully off a bench rest at 800 yards. After the long couple minute drive to the target, I was astonished at what I saw. I saw my 3 shots in a little triangle about 3.5", all 3 shots even hit my 12" red painted bullseye on plywood, and only about 3 inches from the dead center aiming point, they did not hit 8-12 inches low like the 200g SMK and AB were, so I know my clicks are dead on to at least 800 yards, all 3 shots woulda hit even a coyote. My 200g SMK 3 shot group was 4" at 800 yards. I have not yet grouped the 200g Accubonds at 800 yards, but I did at 525 and they shot 1.5". Like I have said before, this rifle really continues to amaze me with its superb accuracy out of the box. I simply cannot believe it. Just thought I would keep everyone posted on how my .300 RUM is treating me.
