DP 85 22-250, Bull barrel, very little wind, 100yds. 55gr FBHP Berger, Everything the same except powder charge. Started at 39grains dp85 and went to 42 grains dp85 in 1/2 grain increments. Velocity went from 3400 fps to someting over 3700 fps. The largest group was .8" (42gr.) and the smallest 3 shot group was under .4". I chronographed all 7 loads one after the other, hot barrel. The 7 shots of different powder charges was an easy 1/2" group. The 42 gr. loading showed little or no over pressure.
Since Wed. afternoon we ordered 48 more pounds of DP85. We ordered 32 pounds last month. This seems to be the perfect powder for the 22-250. Sadly ,as with all the surplus powder, once it is gone it is gone. Think about it, we may not have any surplus powder again until 10 years after the occupation of IRAQ and the powder that will be available could be in short supply at an elevated cost. Probably just one of my unfounded fears. roger
