Hey,
I hope here´s every body, how can get me his experience with reloading 300grs. SP in the 10,75 Mauser. Especialy with Rottweil R902 gun powder. With Quick Load the maximum charge is about 68grs., but I don´t trust this programm so much.And with this charge the accuracy is terrible. I´m thankful for any informations.

IMR-3031 From 54.0 grains to 59.0 grains
Winchester WLR Primer

Thanks for posting ricciardelli, but I know this load and I mean it´s for the 347grs SP bullet. I need datas for a 300grs SP bullet.
(Degol made bullets with 300grs and strong jacket)
