HogWild,
It's interesting seeing that you use Benchmark for one of your loads. My 260 really likes Benchmark. I've used it with 100 gr NBTs in the past and just tried it with 120 gr NBTs; they are by far the most accurate loads I've found. Here's the information:
Rifle
Model 70 action
24" Shilen barrel 1:8" twist
100 gr NBT 2.80 COL
41.0 gr Benchmark
120 gr NBT 2.78 COL
40.0 gr Benchmark
