Is it safe to load a 40 grain load with 150 gr bullets in 308? I have two manuals that list varget. They suggest a starting load of 143 gr. I am looking for a mild load that is not too much above 30-30 in my 308. I am loading 45 gr w/ 150 gr sierra's. It is very accurate, but I want a more mild load for varmints/ pests. I load IMR 4350 for my 243. It is very comfortable to shoot. I am looking for something in that ballpark with 150 gr 308's. I have other powders but would like to use varget if possible. Any suggestions.
