RE: another bullistics question
ORIGINAL: Campbery
Hi guys, I was out shooting my triumph this week and our range doesn't go further than 100yds. Got 1" groups with 100gr 777 and .45 Hornady sabots (SST). I was wondering what my ft.pounds andtrajectory would be at 150 and 200yds? Thanks very much.

drop in your bullet weight, BC, Zero and MV, which is
250g
BC=.21
zer0=100 yards
MV=1835
and you get:
So if you sight in at 25 for windage and zero, at 100 your dead on at 200 your 14 low, 300 your 50 inches low. Chap

RE: another bullistics question
According to my records I have the 250g SW with a BC of .184 not .21, if you go with a 150 yard zero you get this:
So your about 3.5" high at 100 yards and your shooting thru a 6" pipe from 0 to 175. Most MLer bullets drop off the wall at 200, you can get a Barnes 300g Spire Point 45/70 to 200 with a 3.5" high zero at 100 yards. Chap

300g bullets are much better than 250g for long range shooting, better bc, less wind drift near the same drop. More energy downrange too.
Also hornadys bc's are inflated a little, if you are a couple inches high at 100, prolly bout 10" low at 200. PRACTICE, PRACTICE, PRACTICE. And dont underestimate the wind.
