Thread: Run some numbers...If you can please ..

In the weekend I was doing a bit of playing with gongs....with mixed results, all the charts needed a little tweaking but one was miles out... Not sure why

The SAUM was on first hit 4-6-780 but not quite center of plate but didn't take much to sort that


but the 300RUM running the 168 Amax @3380 was well out, flatter shooting.... Is it possible the extra speed has them slipping through the air better than their BC?

I have never had the numbers out so far and I can't quite see why... If I fudge the BC and speed I can get there but I have to change them more than I would have thought I should to get it to match..

What do you guys get for drop with a 100 zero, 2" scope height, 1:13 twist 26" barrel, SIII 8-32 scope that has matched charts with other loads..

From memory Altitude was 168 mtrs- 400 level, line of sight 7 deg at 600 and 12 deg at 780, temp 17deg C What other info do you want?

Dry conditions with a tail wind at 400 abut 5 knots (measure 3.5 but definitely stronger down range), 5 O clock about 10-15++ knots for 600 , and 7 O clock 10 knots 780... No flags put up of measurements taken up the gullies so winds are approx, 2-3.5 wind dialed at 600 as the wind changed to keep it on the gong and try for center... a good challenge in those changing winds ( never missed the 600 but center was not full of hits)

Have you checked your zero setting on the program and on paper D?

zero, scope click value

What are you using Mil/MOA and are your click values accurate?

1/4 MOA and it has allways matched the chart with other loads.... I tried to find my error but couldn't...

I have done a box in the past and I am sure it was on the money.. The SIII sightrons have tested OK in the reviews I Googled to see if it was a scope issue with the turrets being way out (we are talking 20%)

Might do another box test to rule it out... fudging the numbers was fine to 600 but at 780 it was off..... and with that target being in long grass it was farkin hard to spot where they went and was a waste of ammo to blindly adjust around, especially with gusting wind. Pretty sure they were going over the top as low hits on other rifles blew dust of the track...

What MOA did you have for 780 mate?
I don't want to post the ones I ran up in-case they are miles away and I get shit

With barro set at ISA I got 14.3 MOA for 780 yrds with all other data/specs you supplied.
Fixed forgot the look angle.

I chuck one up there

100M sight in at 2" high
at the temp an height you said an i said 1010hps air pressure

at 780M 12 angle at above info gives me 14.2MOA

thats me half pissed tho
