204 ballistic drop

[DLT]

Just an easy question for you guys who are shooting a 204 ruger, 100yd zero what are your drops at 200 and 300 yards ? I checked my drops today and was amazed and a little bit puzzled at the same time. I’m shooting a 39gr bk at 3850. Thanks to those who chime in.

I use .5 high at 100, usually still a hair high at 200, -3 at 300.
I have several 204R's and I notice scope height makes a small but noticeable difference.

Your best bet is to run your go to round through a ballistics calculator takes the guesswork out of it.

Zeroing a 204 at 100 yards is kinda pointless.

I'm not getting that , i've zeroed at 50 yards and 100 yards and never missed my intended targets,but i'm listening.

We all don’t live in the Wild West where you can see for miles

I have a dead on zero at 100, .25 up to 200, and was only dialed .75 at 300. Last time I shot at 300 it was 2.25

Not sure what you are saying?

I’m wondering if .75 of elevation at 300 yards is normal or if I have a possible scope issue. The last time I shot this rifle at 300 yards I had to dial up 2.25 minutes to be on at 300

Ok, that makes sense. First thing I would do is double check your 100 yd zero. Make sure it is dead on. A small error at 100 will be big at 300 yds. Been there and done that! More than once. Lol

It is. Maybe 1/64 high, checked 200 it’s dead on also with only .25 dialed to get there

1/64 Really???

 

[Coyotefurharvester]

What type of sight(traditional scope, digital (thermal, NV) or irons? How high is the sight center above the bore? Is the barrel indexed to 12/6 vertical alignment with sights? Only thing I know, gravity effects all 204R bullets, so there will be a trajectory curve.

So close it’s scary. I was being a little sarcastic

It’s a sightron traditional scope. It’s mounted 1.75” above the bore best I can measure. It’s just hard for me to believe it can be that flat. We was practicing for an upcoming competition getting our 100, 200, and 300 yardages nailed down.

I strongly disagree, but I'm a dialer.
I use 100 yds for a zero baseline, dial up for longer distances. My dope/come-up charts on each rifle is based on actual field shooting of my pet load for each rat rifle and printed up using Sierra Infinity 6 ballistic program. Learned the basics in the military from a MACV SOG fella in RVN, and it's worked very, very well in the intervening years since. All my rifles have a 100 yd zero, no matter the caliber. Only the dope chart differs for each one.

If the active rats are in a congested area of them romping about, then I use the average range setting and have at 'em.

We're discussing the 204R, but for illustrative purposes, this is my dope chart for my 20VT and the 32gr BT or Vgn. Range the rat, dial, allow for wind and watch Skippy fly. All data is in MOA, so the range values coincide with the graduations on the M1 scope turrets perfectly. For over 50 years in the field, it's worked quite well. (For me, not so much for the rats.)





We all have what we feel is the best method to attain reliable hits at extended ranges. This is what has worked for me over a long period of time and sent literally thousands of rats skyward. It's also worked well on my high country and high desert rifles for Muley's here. Very well.

I'm presuming you mean .75 and 2.25 measurements are in minutes on your scope dial. At 300 yards .75 minute would be 2 1/4 inches and the 2.25 would be 6 3/4 inches. That's a big difference to me. My rifle would be right in the middle of those 2.

Are you reading off a scale in the reticle? If it's a SFP scope you have to use the same power to get the same results.

 

[Coyotefurharvester]

With no elevation data, typically +0.5-.6@100 yards, 0.0@200= -4.0@300 yards with a traditional scope center 1.75 inches above the bore.
32-40 gr tipped bullets at factory 204r velocity.
I usually zero center of group 1" high at 100 yds, my 204R,20p and 22-250.

Your right. I’m not using my reticle to measure. I have my target from last session early summer. I will look at it and double check because I do have it written down what it was for sure and compare to this weekend.

.75 sounds more normal. My 16” 223rem only has 3moa of drop at 300yds running 70gr Barnes Hp at 2860 fps.

Is this a SIII Sightron
