Steve - my Pacific manual lists 170gr. with 4064 as starting at 46.0gr. for 2,430fps and max at 51.0gr. at 2,730fps.

There is no data for 200gr., however 196 to 198gr. with 43.5gr. N203 (RE#15) starting at 2,200fps with maximum of 47.0gr. at 2,510fps.

The 225gr. data lists max of 4064 at 48.0gr. and 2,390fps, with IMR4350 start at 49.0gr. & 2,160fps with max of 4350 at 54.0gr. and 2,440fps.

An old friend of mine, retired guide, used the 4350 max load and got 2,450fps from his sporterized military M98 8x57 with the Speer 225's. They worked for him on a charging grizzly for him back in 1978. The bear charged them from uphill on the trail up the mountain - quite steep. The first 2 into the chest frontally, didn't do much, however the second turned the bear. The next one through the shoulders put the stop to him.
