The Best and the Brightest scopes

[uncle buck]

Guns & Ammo Sept 2010 "Gun Notes" page 24 by Craig Boddington made me think a bit about 1 inch tubes and 30 MM tubes...However ...I would first like to say that Foxpro51 already made comment once that he did prefer the European 30 MM objective lens VS the American 1 inch tubes or objective lens since they were a better scope for shooting..Now that I read the comments of Craig Boddington I can see why Foxpro51 prefers the 30 MM Tube over the 1 inch tube...

The article above however revealed that the 30MM objective lens gathers more light then the 1 inch objective lens..  So....as nighttime predator callers and using a rifle...We should use a 30 MM scope more then a 1 inch tube for nighttime shooting.  Mr. Boddington did say that the 30 MM objective lens does come with illuminated reticle's too..So this also would be better yet...Now understand in Europe the American  concept of "shooting Hours" is unknown. Artificial lights are illegal, but if you can see it, you can shoot it in Europe. Hence why Europeans like the 30 MM objective lens tubes..

So how much bigger is a 30 MM compared to a 1 inch scope objective lens?

I always like to do this when I'm bored...Take a calbier and calculate what it would be in MM or MM to U. S. Caliber designation too..  I do like to use the 6MM = .243 cal as my data how to find what MM is:

6MM  =  .243 Cal bullet

.243 Divided by 6 MM = .0405

,0405  then = 1 MM


Back to scopes

30 MM X .0405 (1MM) = 1.215 inches Minus 1.0 inch American tube.

So the 30 MM Scope tube is .215 inches larger then our 1 inch scope tubes..
No wonder it gathers more light ...it's 1/5 + more then an regular American 1 inch scope objective lens.


When us predator hunters buy a scope for low light condition we might want to find which scope companies make the 30 MM tubes and which have the illuminated dot too?

Mr. Boddington referenced The German made Doctor 2.5-10x50 MM with lighted recticle as best and brightest lighted scope.

This post is to kind of make you think about 30MM vs 1 inch scopes.. ...A nighttime predator hunter  might want to have  a 30 MM instead of a  1 inch objective lens..

I have been looking closer to see who has the 30 MM Scopes.  Cabelas sales a Leupold and also one with their name on it..

E. A. Brown sales a 30 MM European tube with an illuminated MIL dot....Now that sounds real good....

Tried to post their web site but it must be down for maintenance..  http://www.eabco.com/
  Brown has them for   $239.00  4 X 16 X 50 and $259.00  6 X 24 X 50 MM
They are called the Hawke Eclipse 30 Side Focus.

UB,

    Another factor is one's eyes...as you git older they tend to require all the additional help they can get to see what you are looking at!!!

Meopta is a good value for 30mm scopes. I think the best scopes on the market for all around use is 4.5 x 14 power.

Has anyone tried Burris scopes?

[uncle buck]

Does the Burris come in the 30MM tube or are you talking 1 inch tube?

[foxtrot]

Burris does make a 30mm.I have a 30mm  1x4x24 made by countersniper on my combo gun. It is an American made scope built like a battleship,very good optics but a little on the heavy side.

30MM VS 1" is not all you need to know. Exit pupil is a huge factor in night hunting,which is the objective diameter divided by the magnification.

So lets say you have a 40mm set at 4x the exit pupil is 10mm,the same scope set on 10x is a 4mm exit pupil.Obviously the larger exit pupil the more light through the scope......
