Went out shooting today to try out some new ammo.The load is 310gr Kieth from MtBaldy in 45colt over 13gr of HS-6 fired by CCI 300 primers in new winchester brass.The gun is a blackhawk convertible with a 4 5/8 bl.Here is where I get confused,@ 30 yards taking a full bead,(in this country means the top of the front sight blade is even with the top of the rear sight blade),this gun hits dead on.No problem right?Well @ 60 yards with the same sight picture it hits 4-6" high,but if you take a fine bead(front sight blade at or near the bottom of the rear notch)you are back to dead on.I am not the smartest tack around but this seems completely backwards to me.If I use a full bead and put it on the bottom of his chest cavity out to 60 he will be in a world of hurt but where do you suppose the bullet would come back dead on?Am I crazy?

Sounds right to me because on those short barrels the front sight is usually very tall. I'm not sure where you would come back to dead on though. I like trial and error to figure that out.

Sounds right to me, too. I'd guess it will be back on at a bit less than 100 yds. You'll need to check it.

+1 -- sounds about right to me too.

I agree with 500WE. With the sight picture that puts you dead-on at 30 yds., you are 4-6" high at 60 yds. When you pull a fine bead (at 60 yds) you have lowered the bbl and are back to dead-on. The bullet is rising out to 60 yds (or beyond). I would guess that you are not far from being sighted in at or near 100 yds.

I would shoot it at 75yds, 85 yds, etc. I would want to know the distance where I had maximum rise and how much it was in addition to the distance where it was back to dead-on.

Good luck.

Bullets don't rise....it's called the Mid-Range Trajectory...Long story short.

from what little i understand the bullet is falling at a constant rate from the time it leaves the barrel to compensate for this and the fact that sights are on top of the gun you actualy sight your gun with the barrel angled slightly up.the power of your charge propels th bullet in a trajectory that takes it up to the aim point and possably beyond.at some point this forward and slightly upward momentem is overtaken by gravity and drag. this point will vary due to several factors such as bullet weight, shape, velocity and air density.there are charts and computer programs available to figure all of that out and tell you the trajectory. but unless you plan on regularly trying very long range shots. the best method is to grab a box or two of bullets and try them at numerous distances.then document and remember the results.

Correct the bullet crosses the sighting plane twice.
