Thread: What's going on here??

He is worried about the spread in speed. 16" bushpig with the chances of shooting out to 400m when he hunts south island.
Re chrono the drop for the last 3 works out to the speed on the chrono but could that cause an issue shooting out towards 350-400 if his speed is a bit crook?

bear with.... have data for 165grn ballistic tip so in ball park. his will be slipperier so slightly better,
2400fps 2.8 high hundy-31.6 at 400 -64.1 at 500
2300fps 3.1 high at hundy-35.1at 400 -70.3 at 500
bboth sighted for 200yard zero,
so 4" difference at 400 and 6" at 500 yards.....so if aiming for fat part of shoulder,it would be dead. at worst slightly low of high but still dead.

speeds given are 100fps apart same as his load data from chronicgraph...

168grn nosler solid base
2500fps at muzzle, at 400 yards-29.4
2400fps at muzzle ,at 400 yards-32.5
2300fpsat muzzle, at 400 yards-36.0
7" with a 200fps difference in speed

yes and sight the friggin thing in couple of inches high at hundy.....makes heap more sense.

Old rule of thumb for projectiles going at between 2400 and 2600 fps 3 inches high at 100 equals dead on at 200 and 3 inches low at 230 yards, so basically point and shoot to 250.
