Following the advice of the kind and helpful members here, my Springfield Cadet is doing what I think it should at the 100 yard mark and now I would like to extend the range a ways. First question, was the 405gr carbine load intended for the Cadet with Buffington rear sight? Secondly, what velocity do you suppose the original loads were?
My current load, which can be adjusted up or down a little without loss of accuracy, is a 405 hollow base with a b.c. of .225 launched at 1370 fps. Using those numbers it looks like my bullet drop is a little under 43 feet at 600 yards. That is intimidating. Of course I'm intending to work out in increments of a hundred yards. I will soon discover if this is a fool's errand. So I guess my last question is, has anybody had any success shooting at mid range using the marked increments on the Buffington? And yes, I understand that I could mathematically compute my rear sight height and set it with vernier calipers, but just think how easy it would be to lob one in using the sight as it was designed. Thanks, Flintlocke
