[QUOTE="Jud96, post: 1181979, member: 69478"] I have a great load in mine with 208gr A-MAXs but you can use the same load with your 200gr Gameking. I use 74 grains of IMR 7828ssc with the 208 and that's the book's max load for a 200, but I have no pressure signs and my primers aren't even flat. Start at 72gr and work up until you see pressure. I am getting 2950fps with that load and the accuracy is amazing! First and only group with this load printed a .176 thousandths three shot group at 100yds! Going to shoot is some more and see how it does. When I was tinkering with the 190 Matchkings I couldn't get anything better than half inch groups and most were around 3/4 inch. My rifle just doesn't like them. I did achieve good speed but even the lighter loads didn't shoot. I tried 7828 with the 190s and my max load with it went 3050fps while the max load with IMR 4831 made 3125fps. I think Retumbo will be way too slow with anything lighter than a 208gr. [/QUOTE]
