I have so much IMR 4198 that I will never need to buy more, or try H4198. IMR 4198 is my favorite powder in the 222. I like IMR 4895, but switched to Varget in the mid-1990s. With the 4350s, I use whatever I have on hand in the 30-06 and 270. If I'm going hunting, I prefer H4350. I have always found IMR4831 to be a winner in 270 loads, but like the H version just fine.
