I started ringing round today to find out what gunshops in the northeast stocked in the way of powders and bullets . I started talking to one shop and when I told them I'm new to reloading they began to tell me how they did it .... this guy said he loads .243 100gr at 4 different powder weights. He does this so he doesn't need to alter his scope , one green is for 100m, another blue for 200m, green is 300m and the red (the hot one ) for 400m ! I tried to hold my laugh in as I thought about a fox at sitting at 150m ... "which round ,green or blue!"
Staying clear of that place now.
