A Western Powder, has had good reviews.
check, as I had to search for ramshot.com for data.
My bud has some TAC, that is from the same company. I hear the xterminator is a cleaner burning powder.
Wil, you da man. I asked you for some data on TAC, but I found the Ramshot site. I shoot 52-69 grainers, so will Exterminator give me better results through that range, or would TAC be a better powder across the .223 range up to 80 grs?
TAC gives me high SD's and not very good accuracy with 55's but it does very well with 69's, sd's in the single digits and very good accuracy.
Xterminator works great with 55's and lower. 3200 with Montana gold FMJ's sd of 12 and around 1" at a hundred. It will shoot tighter with 55 grain Nosler Ballistic tips.
