Hi everyone, Has anyone loaded the new barnes TTSX in 180 gr. with retumbo powder. I have the stock accumark 30-378. I get great accuracy with the 180 gr. sierra pro hunters, but I didn't like what they did at close range last year on a moose. I want a bullet that will stay together better. I like the sierra bullets but I think the 30-378 might be a bit fast for it. They work great in my 300 win. I am loading the sierra 180's with 107.5 grains of Retumbo with fed 215m primers. When I look at the barnes loading data I see the max load for the 180's is 105. grains. Is there a reason for that that? Do the Barnes bullets create more pressures? I bought some 180 gr TTSX and was wondering where to start. Any info or recipes on any bullets or powders would be greatly appreciated. Thanks , Malibual0.
