I have shot my rifles in some fairly windy conditions over the years. To be honest it really depends on how the wind is blowing. A head or tail wind really has no effect what so ever on your bullets.
Plus I never worry much on shooting out to 50 or 100 yards.
So unless I am officially sighting in my rifle for a hunt then I like to shoot in different and varying winds. IMO I consider it good practice for field conditions.
Cross winds can be very tough on round balls. And they are also noticable on large conicals when shooting to 100 yards or beyond. But for 100 yards shooting and less the wind is not a big issue. Unless it is a full 90* wind. And how often does that actually happen?? Tom.
