sight adjustment for 100yds

The weapon is a Dan Wesson Model 744, HV, 8", with factory DW sights. At 50 yards the sight is bottomed out so I have plenty of adjustment for longer ranges.

For a starting point so I am not skipping bullets over the berm, how many klicks up for 100 yds?

It all depends on the load you're using, so you will need to find the trajectory and work from there, or just "fire for effect"

It always comes back to science and the math doesn't it?

Thanks for the reply. I was just sitting here wondering about this and that, thought there may be a very basic rule of thumb for moving from 50 to 100 yds.

Not ready to start firing at 100 yds anytime soon as I'm working on a commercial cast bullet and load combo that does not lead the barrel. I guess I could go with my jacketed load, but I would just as soon not reintroduce copper into it right now.

I do have a 7.5" 44 mag RH I could fire copper through but my range does not allow pistols under 8" on the 100 yd range.
 
How many clicks...?
Absolutely no way to predict.

Fire it at 100 and record the drop from point of aim.
I'm "predicting" 12 inches.) ;)

Take a set of calipers to the range.
Assuming an 11" sight radius:
raise the rear site 12*0.0027"/MOA ~ 0.032"
 
a little at a time

I don't know the click value of your sights and I'm way too lazy to do the math,,,I would start at fifty and get it sighted to hit high on my target at fifty, then move out to 75 and do the same thing then try 100

In the older Manuals I have seen tables that answer this question . You need to know bullet weight and speed and the table will estimate drop .

On my own ranger my Super Blackhawk shooting dead on at 50 yards and shoots 11 inches low at 100 yards . I am shooting 240 XTP at 2150 fps .
 
Inches of drop rather than # of clicks

I don't know the click value of your sights.................

granted, asking for clicks was in retrospect a poorly thought out (make that a stupid) question.

A "more better" question would be; "how many inches of drop can I anticipate moving from 50 yds to 100 yds with a 200 gr RNFP Hi-Tek coated cast bullet pushed by a yet to be determined weight of IMR4227?" I am hoping to get up to 1400 fps without leading.

Granted, I would rather be pushing a 240-260 gr GC bullet, but working with what I have on hand.
 
5 inches.

Again:
- Go to the range
- Fire and measure drop
- Raise rear sight 0.0027" per inch correction req'd
