I have a markV deluxe in 300WBY that I have had a little over 10 years. I bought it well before I started loading and got into the long range stuff. I don't even think I have 2 boxes of factory weatherby ammo out of it and it shoots right around 1". Anyways I was gonna sell it but instead I am now thinking I should start to load for it and see if I can get more out of it. I have no experience with the 300WBY or loading for any weatherby's for that matter. does anyone have a pet load for them or some suggestion on where to start???
