No spring season here, but it looks like a lot of fun. I love those nice big coastal blue's, my favourite grouse by far. In September when they have been gorging on blueberries and huckleberries they are fantastic
Sounds like your son is growing up nicely and have excellent taste in cartridges I might add........
I have loaded up some 200 gr Hornady's with Trail Boss before and will have to see if I can get them down to around 1200 fps like yours. If not 250's like you suggest will work. We did some loads in my wife's 6.5x55 before when she was learning to shoot, I'll have to see if we can reduce it enough to get the same speed.
