With the 4198s: 17 FB, 17 Mach 4, 17 Rem, 218 Bee, 221 FB, 223, 30-30, 308, 30-06, 35 Whelen, 444, 45-70, and likely a few others that slip my mind at the moment. For the two small 17s and the 444, H4198 produces the best velocity and accuracy combo. In most of the others, it is just efficient and accurate.There are some cast bullet only applications in 243, 6.5 CM, 270, and 280 where I use IMR 4198. That will likely change, as I now have more H4198 than IMR.
