Hi, ran into a new problem. I am reloading my 7mm ultra in a remington sendero. I wanted to match factory ammo (3400 fps w/ 140 gr. nosler) Here are my results with reloader 25:
90.5 gr = 3225 fps
91.0 gr = 3202 fps
91.5 gr = 3224 fps
92.0 gr = 3281 fps
92.5 gr = 3280 fps
93.0 gr = 3459 fps
Any one know why with more powder there is less fps? Or why the jump of 180 fps with only .5 gr more?
Next problem. The 93 gr load was the most accurate load. It was a one hole group with 5 shots (this was the only load that matched factory ammo for groups). However, the brass was a little shinny on the bottom (no sticky bolt or other signs of pressure). I shot the rounds at 45 degrees. Would this load be dangerous at 95 degrees on a antelope hunt.
Thanks for your thoughts.
