Thread: Mil/Mil vs MOA/MOA

MOA MOA for me, but doesn’t really matter which really as both are just angles. As other say, it’s easy to overthink this, but you can just think in clicks and have a drop chart taped to your stock. I don’t like busy reticles and measuring adjustments using mil dots isn’t my thing.

Some of those factors make very little difference but they all add up. That’s why I’m not a fan of CDS type reticles too. I don’t see the point of having a good quality dialling scope and then limiting accuracy to the set parameters dictated by the dialling system.

I did a test in the US on temp effects with my .300 Win Mag. Can’t remember exact temps now, but they were about -2C and +24C. At 500 yards there was a 19 inch difference in drop with the same loads. Admittedly that’s a big temp range but it makes the point about the limitations of fixed inputs.

This is a very good point.

The drop charts I use are created only after I have validated the drops at 300m and 500m usually, 250m and 350m for the .223. But when I do the charts will bias the outcome. I'm usually pretty good at remembering to set the climate and altitude.

Last week one cold morning I started missing at 540m after going well for the two hours prior at ~250-450m. Why? It wasn't that cold, but it could be up to 14-16°C cooler than when I did the drop chart. That's over 6" at 540m. I will recreate these charts with a median temperature for winter and summer. BTW despite their limitations, when its all on and you need to dial different ranges in quickly, a drop table is bloody helpful, better than cocking around with the phone.

The other very real possibility is the temp change has put your load out of the "node". Especially if you were on the edge of it in the first place.

That is why people have more accuracy and precision than they need.

Just make a set of cards for density altitude zones. Mine are color coded and laminated on a key ring.

Mil/Mil with cards for density altitude will do me.

I can concentrate on wind doping. The rest is trivial by comparison.
