I am in the process of having a 35 whelen built. I have settled on a fixed 4x scope for hunting ranges. The heavist all copper bullet that I can find for California is 225 TSX. I am hoping for about 2600 fps. Where can I get a chart showing the flight of said bullet? I want to start paper shooting at 25 yards with the low power scope. I want the 0 set for 200 yards, but don't know how to figure how high the bullet would be at 25 yards. Help? Gary

Your reloading manual would be a good place to start. Or Barnes website.

My Barnes reloading manuals start giving bullet flight at 100, 200, 300... but not 25, 50...

look under medium range trajectory (barns manual)

If you know the bullet diameter, velocity, weight in grains, and ballistic coefficient you can get the path right here

You can play with ballistics calculators and load manuals all you want but you will never know where it really shoots until you try it with actual loads at actual ranges.

Sounds like your problem is that don't have a real range beyond 25 yards -- which is why you are asking such questions.

I personally would not take/trust a 25 yard "ballistic program zero" and then hunt with a rifle at 200 yards. Find a range and sight your rifle in at 100 yards and then 200 yards. I would bet a bottle of single malt scotch that if you sight in 2 inches high at 100 yards that your Whelen will be hitting pretty close to the bull at 200 yards.

Thanks for the response! I did not think about a ballistics calculator on the internet.

Gary, If you will email Greg at ggibbs08@yahoo.com he will give you the exact information you need. He shoots a .35 Whelen and has made some unbelievable shot. He shoots the 225 TSX at about the velocity you want. I shoot two, but my old eyes just don't work quite as well as his.
good luck,

Don

I second the motion!

Just be sure to click on the English language site (look for the Union Jack icon), then be sure to select the English/American (not "metric") units.

Lots of fun...

one last thing; once the calculator opens, choose "define your own bullit"

enjoy!

With a 225 grain bullet at 2600 fps, why not zero it at 250 yards? You'll be 4" high at 100 yards and only 5.4" low at 300 yards.

I shoot the 225 gr. TSX at 2710 FPS from my custom Mauser with 1 in 14" twist barrel. The load is maximum in my rifle and I suggest starting at least 4.0 gr. lower. The load is 60.4 gr. of RE15, Remington brass, Winchester WLR primer and of course, the 225 gr. Barnes TSX. My barrel IS 24". Again I have to epeat myself but don't try starting with the load. Cut back about 4.0 gr. and work up. The only animal I've shot with that load so far is a cow elk and the bullet was a complete pass through almost the full length of the elk when I hit her at 150 yards as she was running away. I did work up the load during Tucson's very hot summers. Probably was about 105 the day I did the shooting and it was slightly above freezing when I shot the elk. FWIW, I sighted in three inches high at 100 yards and it puts me in the ball park right at 250 yards.
