thanks marrakai for the reply,lve talked to people who are using it ,they have said there was no problem with it either but better safe than sorry so l emailed hodgons about it and havent heard back yet,but l have been using sc 4831 with some amazing accuracy,the reason l was asking about varget since l live in central british columbia,and varget seems to be so insensitive to temperatures,and l have lots on hand for other calibers l shoot.
