Sorry if this has already been asked before...

I haven't seen an actual chart of how flat the 17 shoots. If I sight in dead on at 50 yds., what will the impact be at 25, 75, 100, etc.? I intend to use mine mostly for squirrels, and I 'm sure lots of shots will be under 50 yds. Will I have to aim high or low at 25, etc?

Does anybody have an actual chart worked out? I thought there would be one on Hornady's page, but no dice. Thanks for any info.

Ballistic calculations here.

I ran the numbers for a muzzle velocity of 2550, 2600, and 2650 fps and posted the drop numbers every 25 yards out to 400 yards. If I post the numbers here, the formatting won't be correct. The info is here: http://www.varmintal.net/17hmr.htm
The zero is at 100 yards, not 50 yards.

Good Hunting... from Varmint Al

George,

This is my field test chart. The range is home made with small elevation changes between targets but basically flat. Same spot we use for 500 yard big bore range.

I am using these numbers until I collect more data in the next weeks. It does differ from the ballistics software so I will keep testing to see what I can learn.

Yards........Impact Point

0 ............-1.625
25 .......... -0.625
50 ...........-0.125
75............. 0
100 ..........-0.5
125...........-1.5
150..........-2.75
175..........-4.25
200..........-7

....Edited to add..........

Al's charts are good. Looks like close to 2600 FPS data I got but the 24" barrel should not get that).

You guys are way more qualified then I am to talk about this, but I shoot the Savage 93R17 and I found that if I zero at 50 yds it is dead on at 100 yds.

I have no idea what changes to expect with other barrel lengths/guns.

Hello,

Last fall, before I came across any ballistic charts, I too did a field test with a 1717HB. My results are somewhat similar to Gillie Dog's.

10yds = -1.125
20yds = -.875
30yds = -.625
40yds = -.375
50yds = 0.0
60yds = .1875
70yds = .375
80yds = .4375
90yds = .625
100yds= .375
110yds= 0.0
120yds= -.5
130yds= -1.0
140yds= -1.75
150yds= -2.5
160yds= -3.25
170yds= -4.0
180yds= -4.75
190yds= -5.75
200yds= -6.75

I'm fairly confident of the drops out to 110 yds, but from that point on the drops are based only on a single grouping of three at each 10yd increment.
