How to correct drop?

I think you’re misinterpreting what lawnboi and castle are saying or I just disagree.

If the dudes asking these questions “true” a ballistic calc based on an AB custom curve and measured velocity at ranges like 600 yards, they are more likely to worsen their data by “truing” in the impacts from current conditions they are unaware of than actually improve that baseline ballistic profile for future use with different conditions.

You disagree with trueing rifle quick charts based on real world hits at yardage? Interesting.

Whether you true velocity or blindly trust an app based on chrono MV, etc you are missing shots on animals without confirming at long ranges. See cold bore challenge overall results for what actually happens when guys shoot “long range” without confirming hits and trusting apps.

Both methods can get you very close in lots of cases, especially inside 600 yards since you mentioned that particular range, but “close” and “confirmed” is the difference between kills and misses.

I certainly do with proven data, do you true in the field before taking a shot?

I true at home in hunting terrain shooting at that particular rifles killing range and then build quick charts based on planned hunt DAs.

You mentioned “taking it up a couple clicks” after sighter shots. That doesn’t always work when trying to kill things was what I was trying to convey, probably poorly sorry.

OP where are you at in CA? I’ll be in CA 2 out of the next 3 weeks. I can bring my MIL Dot spotter out and give you a hand working out your setup if desired.

I can also bring my garmin chrono along and we can “do it both ways” using a known MV so you can see the process using a couple different method. PM me.

So we are either blindly trusting a velocity number coming off of alien technology or environmental effects we can only confirm once we send the bullet?

I shoot a lot, plenty of confirmation gets done. Environmental effects are a guess. Enough shooting and you can start to make some educated guesses

Anyone can true data if they want. Iv been screwed by it, and I pass it along when people ask. Because I don’t think it’s as easy as shooting a few shots and fudging numbers in a solver. I see a ton of new shooters thinking they need to true at 5-600 yards.

And I kill animals too.

As I said somewhere before good zero's aren't usually a one and done proposition

Explain this please.

and neither are offsets or most anything else we do. It takes a little time and effort to repeat and test to come to a good reliable setup with full knowledge that day to day environmental's are going to mess with you.

This as well please.

Whether you true velocity or blindly trust an app based on chrono MV...

I don't recall folks saying they don't confirm app results at the range, certainly not me. I confirm at 100 yd intervals out to my self imposed max range prior to hunting. I find the app results generally very good but not good enough to rely on for hunting without confirmation. Once results are confirmed good at the 2000 ft elevation of my home range I run the app again and create a quick chart for the hunt elevation and likely environmental conditions. I know that there is "on the spot" technology but I don't see a need for that at my max range of 600 yds.
