docone31, pdawg, et al:
I was going to hold off shooting the Whelen until next week but I decided at the last minute to put together 10 rounds last night and fire them today.
It took three out of the 10 rounds to get the elevation adjustment dialed in, which is why there are only 7 rounds on the attached target (yup, all 7 rounds were shot with the same sight setting). I'm going to fire 25 rounds, a little faster this coming Monday.
Does anyone have a clue what could be causing the whacky flyers?
Here are the load spec's:
SAECO 352 cast of BHN 10 point something metal; first PT sized to .356" and patched with two wraps of .002" tracing paper up to .3625"-.3630"; then sized to .361" to fit the chamber snugly; loaded over 50 grains 2520 and run through the chronograph with the following results:
n=10;
high=2252;
low=2151;
mean=2174 if including 2252fps round; mean=2166 if not including 2252fps round;
range=101; (another grain of 2520 may lower this significantly)
std. dev.=28.8 if including 2252fps round; std. dev=13.4 if not including 2252fps round;
Thanks for any input,
MJ
