I have a lefty model 70 in a 338 win mag. I used the go to powder with 225 AB and Hornady 225’s. Talk about frustration mess with seating depths etc still frustrating. So I pick up some 250 AB and holy Shinto talk about a different rifle. This thing loves the 250 AB so I bought more from SPS. I need to find some 250 Hornady’s SP.
