I worked up a load for my .300 RUM last year and killed two animals with it. The load consisted of New Remington Brass, Fed 215 Primer, Hodgen Retumbo 101 Grains, and Nosler Accubond 180 Gr. bullet, vel f/s was 3387 (average) and my groups were around 1" to a 1 1/2" Not being one to sit back I want to work up a new load using a 200 Gr. Accubond with both Retumbo and RL 25, also I want to try RL 25 with the 180 gr. I have a Nosler #5 loading manual and it doesn't list either the RL 25 powder or the accubonds. I am looking for a safe starting load for both the 180 gr. and the 200 gr. using RL 25. Thanks
