Thread: Ballistic Calc Help

The saga continues below.

Thanks for all the input.
- To adjust the MV to get to a 3MOA @ 300m would be 3300 fps. I don't think is that's in the realms of possibility, right? Could be but majorly contradicts the factory specs and the chrony readings.
- Have checked the zero a few times and am very confident it's 100m. Will check it again sometime this week out Kaitoke.
- Trentham does both yards and meters but there was a lot of chatter the other week if we were supposed to be shooting yards or meters and it was definitely 300 meters. Shooting the fallow at 315 at the same 3.0MOA adjustment validated that for me.
- Measured thse scope height and is 1.75 inches at most, def not 3inches
- Checked the scope and it is supposed to be .25 MOA adjustments. Might have a go at the test you mentioned SS that'd be interesting.

Today, Trentham were shooting 800y / 900y. That's too far for me and I wasn't even thinking of going but got a bit fed-up trying to figure out the theory so at 1130 said bugger it and decided to go and see if I could get something on the target using the adjusted solution (changed site height to 3inches; which aligns to 3MOA @ 300m).

Solution was 16.75MOA adjustment for 800y (730m) and despite it being a day of strong gusts, some distracted shooting from myself (I never seem to shoot well with others around), and having never shot out that far before, I ended up with the below.



There's not a great waterline but I think the distractions (didn't follow my process ) and the strong and gusty headwind, it's somewhat validated my solution. Granted, won't be trying to shoot a deer at this range as I've obviously got some work to do but I think the MOA adjustment of 16.75 @ 730m is accurate.

Thanks again for all the input. Hoping to have a crack at something a bit closer (~500m) this weekend and will report back.
