Well I started this thread and the 155's have been the most accurate bullet tested in a 1-12 Savage F class factory gun...(until I put five 130 TTSXs with Benchmark into a 40 caliber hole in a 15-18 kts gust storm...but that is the ONLY smaller group of 20 test loads).155 Sc and Varget and 210m primers... even the case does not seem to matter, just realize some brass has very different capacity!
