The difference between 50 & 100 yards

[Pic IN the Casa]

Shot my CVA Wolf today. 100grn BH209, Hornady 300gr SST. Sighted for 50yds and was dinging the bulls eye. Move back to 100 and consistently hitting 4" low.

Seem a little extreme or normal? I always shot Powerbelts and 777 pellets out of my old Wolf and can't recall that drastic of a drop. Perhaps I am not remembering correctly, though.

Yes thats about right for dead on at 50.

 

[stringtalker]

My wolf is sighted in dead on at 50 yards too, but it is also dead on at 75 yards. Don't think mine is going to drop 4 inches in 25 more yards. But I am shooting alot smaller bullet

 

[fairchaser]

If you sight in at 100 then shoot at 50 you won't be 4 inches high. It's a math equation but at the same time you can be off some at 50 and not realize it. Think about it this way. Everything is dead on 6 inches from the barrel.

 

[Matador]

That sounds about right for that bullet weight.

If your range is only 100 yards max, I'd back your load off a little and see how that goes. The bullet will rise some before flattening out.

Two inches high at 50 = dead on at 100 with just about any 50 cal sabot I ever shot

With your recipe a 50 yard zero should only be 1.5 inches low @ 100 yards and 0.5 inches low @ 25 yards and 6 inches low @ 150 yards. With a 100 yard zero, you should be hitting the target .75 inches high @ 50 yards and just a hair below bullseye @ 25 yards and 4 inches low @ 150 yards. Play around on the Nikon Spot On website. Your load should be traveling around 1900-1950 fps.

He's shooting a Wolf. I doubt he's getting 1950 FPS with a 300 GR pill out of that short of a barrel. I've chrono a lot of loads out of a wolf with that same load and they are hovering around 1800. FPS.

Even with that load travelling @ 1800 fps, a 50 yard zero would only place the bullet around 1.75" low @ 100 yards. And with a 100 yard zero it would strike the target around 1 inch high @ 50 yards.

Sounds like I need to zero at 100 and start the process over? Good thing is where I hunt I rarely can get more than a 50-60 yd shot.

That's exactly what I would do. You're already on paper at 100 yards, so all you'll need to do is adjust your scope to hit dead on that distance and then shoot at the other distances to confirm those ranges.

Don't know much about how one should drop with BH209 but with my inlines that I have/had with a 100gr charge of pyrodex (loose or pellets) and a 250gr bullet I sight in for around 1 1/2 -2" high at 50 and the worst drop was about 1 1/2" below center. So with a 300gr bullet that sounds right. Also I never take ballistic info from a chart or computer as gospel just a reference as to what it may do. Each gun/shooter is different so if with that load it hits 4" low and is consistent then I would say that somewhere near the 50 yard mark the bullet reaches the apex of its arch and starts dropping. Personally, just personally, with that info I would want it hitting around 1 1/2" high at 50 so it would only be about 2-2 1/2" low at 100. I like those impact points to allow for error just incase my hold is a little low or high when the moment of truth comes.

The information that I have posted above is fairly accurate. I have followed the Nikon Spot On info from their website with several different guns and loads and they have all been practically '"Spot On." But if you noticed, I also advised to shoot at different ranges to make sure the bullet hits where their website says it will. And I just checked Blackhorn 209's load data on their website and the original poster's load is traveling @ 1850 fps which still matches the range distances that I posted.

I can tell you, sight dead on at 50 and you will be 3-4 inches low at 100. I had my rifle sighted in with a 250gr powerbelt aerolite and then went to the 300 and guess what? 3" low at 100 compared to where the other 250 hit.

Always go out to the range and LEARN your equipment, don't just take info from the horses mouth and expect it to be correct.

 

[SKFOOTER]

Nope. Sight in dead on at 100 yards first and then shoot at 50 yards and see where it hits. And Powerbelt are at the bottom of the totem pole when it comes to muzzleloader bullets.

 

[FrontierGander]

so i have heard. Sure do a job on deer and elk though! Poor results are normally from a poor shot.

check out this cow my dad dropped with a single shot with the 300gr aerolite. Not bad for a 67 year old taking a 140 some odd yard shot free hand and standing up.

I am using 100 gr. volume BH205, and 250 gr. Barnes TEZ sabots in my knight. I sighted it in for 1" high at 50 yds. and when I shot at 100 yds. it was surprisingly still almost 1" high. I like Barnes bullets.

Which Knight rifle do you have?

That gun is a shooter!!!
