hi any of you guys using vihtavuori N140 in your 243 i have got a tub and may give it a go im using 85 grain bullets and im a bit unsure about the reloading data as it just gives a range of bullet wts from 80 to 85 grains. i have never used this powder before so any advice will help or do you think this powder is the wrong choice and i should stick with aa4350 which fills the case up into shoulders any advice. ?
