V. SmithLow Temperature Powder for 223
Good Morning Guys . I follow this forum a lot but don't post much . I am about to develope a 223 load for late season use and was curious what powder you guys recommend.The Max. low temp. would be -5F and the powder would have to meter well . Mag primers would be used .

stillbeemanI use H335 but it doesn't say its temp insensitive. I don't know if -5 would affect it or not. The mag primers would make a difference. It meters very well.

seafire2Varget, Benchmark and I believe H 322 say that they are not temp sensitive and all three make a good accurate 223 powder...
