Guys,

I have reloaded some 230 grain WFS and am using Pointblank software to track the different loads. I cant find anything to give me ballistics data for 2.5 inches high at 100 yards.
Can anyone help?

Thanks,

I don't know the FS line that well to guess what caliber a 230 gr FS might be?

PointBlank has under misc. functions a calculator to find the BC from muzzle and 100 yd velocities. Perhaps WW's site has the ballistics on that bullet whatever it is to input into that calculator.

SkiBumplus3,

What I would do is dink with the target distance until you get the 2.5" @ 100yd.

Example:

.284 Cal, Nosler #28140 BT-H, 140 grn 3001 fps.

251 yd. target zero =

----------------------------------
Range: 100yds
Elevation: 2.51 in
Velocity: 2812 fps
Energy: 2458 fpe
ETA: 0.103s
Drop: 2.01 in
Max Y: -0.08 in
10mph Wind Deflect: 0.57 in
-----------------------------------

Would that get the data that you're looking for?

You might want to ask Dallan if he can enhance the software to add that feature.

Take Care,

-Steve

What am I missing?
I can't see where the bullet is 2.5 inches high at 100 yards.

Hello Skibump3,

Steve is right, you will have to find it by trial and error. You can put other numbers in the "Targ Dist" block, and then hit the "Re-Compute" button at the lower left. Vary the target distance up/down until you get 2.5 inches at 100 yards. Based on the chart that you posted, I'm going to guess it is around a "Targ Dist" of 225 yards.

Bill

Thanks guys. The chart looks accurate which would be 2.5 inches high at 100 yard is 6.5 inches low at 300 yards. The numbers have different results and that created my frustration.
The caliber is .338
