Yesterday I went to the range to test the .25-35 load using CCI 200, 27 gr. BL-C(2) and the 117 gr. Hornady RN .257 bullet. I also shot some more of the load using CCI 200, 34 gr. BL-C(2) and the 75 gr. Hornady .257 VMAX as well as the factory S&B 6.5x52R for comparison of both trajectory with the sights set for the 117 gr. RN load and group sizes out to 150 yards.

Interestingly, the average velocity of the new load (.25-35/117 RN/27 BLC(2)/200) was 2282 fps for 1353 fpe. This is some 200 fps faster than the S&B 6.5x52R load and the sights had to be adjusted to bring the POI to just 2" high at 50. This put this load right on at 100. What is really interesting is that the S&B load is right on at 50 AND 100 with this sight setting! Must have something to do with the dwell time. The much faster .25-35/75 VMAX/34 BLC(2)/200 load (2832 fps for 1336 fpe) still impacts the target 6" higher at 50 yards and 4" higher at 150 (it didn't even hit the target backing at 100 so I couldn't measure how high it was there). Groups at 100 were 1½" for the 117 RN handload and 2-3" for the S&B factory load. The 117 RN handload fell into even tighter groups at 150 (maybe I was just holding better?) and the 75 gr. VMAX kept right up with it for grouping ability.

There is virtually no "kick" with these loads, generating about 4-4½ ft lbs recoil in this 6 lb rifle.
