i load my ultra mag with rl-25 and accubonds i use 96gr. of rl-25 with federal primers and remington brass to an over all lenght of 3.680" and i am getting 3500 f.p.s out of a 28 inch schnieder barrel hope this helps
Horse, I have a bone stock BDL-SS that I shoot the 180gr Gameking out of and 94.5gr of RL-25. I usually hold about 3/4 MOA with this load. If I recall, I started seeing pressure in my rifle around 95.0 or 95.5 gr.
i would not reccomend starting with 96gr. it is very hot!!! i would start around 90 and work up. no two guns shoot the same one of my friends guns shoots 92gr. and 180gr. triple shoks and shoot 3/4 inch groops out of a stock remington 700.
