Cz550 sight question

I have 2 CZ 550's- 458 lott and 30-06. Sights are different- 458 is express sight with a shallow V and 2 mm front bead. I got a brass 3 mm bead fitted on the existing bead so the centre of the bead is unchanged. That is dead on at 75 m with a combat hold ie the centre of the bead is where the bullet lands. The 3006 has a u shaped back sight and is dead on with a 6 oclock hold. 2 different purposes- the 3006 allows me to pick my target and aim small, the 458 is set up to put the bead on the target and pull the trigger.
 
what you have not mentioned in this exercise is what distance you would like to have you sights zeroed... I would assume that your Rigby would be different than you 375..
By using a trajectory calculator such as JBM
https://www.jbmballistics.com/
you can figure out where you bullet is crossing the line of sight on the way up and down...
As it is with your 416 shooting 2"s high at 50yrds it would be crossing the line of sight on the way down just short of 200yrds
For example my 505 Gibbs has express sights only.. using a trajectory calculator I determined I wanted my load to cross the line of sight on the way up at 30yrds ... with the bullet leaving the gun roughly 1/2' below line of sight it crosses at 30 stays within a 1/2" above line of sight and crosses on the way down at 110 yards
Your 416 is shooting high so you need to lower the rear sight or raise the front '
If you are so inclined you can roughly file down your rear sight at the range until it is shooting where you want it then finish it at home using Cold Blue to re-blacken your sight
 
As my eyes got older, a ghost ring (not huge) closer to my eye, became far superior to a notched rear. Even in my late 50s I coul ring the 600 yard steel (18" gong) with my FALs.

Great fun in the military surplus rifle matches we did. FWIW, the worst sight of all was the K98 Mauser.

For closer and fast (shotgun with slugs to 100) I used a Williams rear with the aperture removed - making for a largish ghost ring. Your brain will automatically center the front sight in the ghost ring.
 
For target shooting, I prefer the 6:00 hold. However for hunting I prefer point of aim, i.e. the bullet hits just above or at the top of the front sight. Peeps or Ghost Rings work best for my old eyes.

I've never liked it.


That's a great diagram.

I use a mixture of the standard and 6 o'clock hold sight pictures.

When I'm zeroing a hunting rifle I take a 6 0'clock hold for a sight picture and I adjust the sights so that the bullets impact to where I'm aiming. I find that method provides me with a clearer aiming mark. So I guess that's using a standard sight picture to hit the bottom of a bullseye target.

Then when I'm hunting I just use a standard sight picture.....aim where you want to hit.

I am righthanded, so not interested in the rifle, but I have a 375 RUM and 350 gr bullet loading data is very hard to come by. If you could reply with information regarding your loads I would greatly appreciate it. Thank you, Ray Boone, Leavenworth, WA

Hello - I was looking at your post from several years ago regarding the Winchester 300 H&H. Any chance you still have the lefty M70 300 H&H for sale?
Thank you, Mike
