Hi All- I am looking for powders which are very accurate, and also interchange between these loads. Initial research shows that for cost/plinking TAC is great for 55g and 75g. For more precision and less temperature sensitivity, Varget is better. It is over 110 here for 2 months per year. You wouldn't believe the wierd s**t I see in my groups at that temp., even with a really good chamber fan. I want to initially go with 2 powders. All reviews said they both metrer well. Let me know what you think about my choices please.
