Agreed. That is why I love Iron Sights! Now having said that, I have never had a scope failure and that covers about 45 of my 59 years. Burris and Leupold mostly. I remember Burris used to advertise their dual springs assembly. Don't know if that was important. They also had a PosiLock that I am sure worked pretty well as it locked the adjustment mechanism in place. Don't think it sold well enough to keep though.


I like some of the ideas brought out to beef up the constantly centred system but think they would be even more useful locating a simple, etched graticule instead of the whole erector set, which must weigh at least 10 times as much. I even worry about internal windage in either system. It doubles the complexity and adds a screw to possibly rub past twice at each shot. Putting windage into the mounts is hardly rocket science and German and Austrian makers were happy to leave it there for decades.

Using reticle-movement mechanisms such as this or, even better, a system evolved from the old B&L Custom scopes and mounts, I can see the possibility of optical sights even more secure than iron sights, which can be vulnerable out on the end of your barrel and sitting on unsupported cross arms.

I like it with a 480 or 500 gr. bullets at 2000 FPS plus and try to get 2100 at least, thus I always use a 24 inch barrel. A complaint Ihave is load density, to get 2000 plus you must cram the case, and I don't prefer to do that..My approach to the 45 caliber big bore is the 458 Lott, loaded down to 2200 FPS..That is about a ideal elephant or anything else killer as one could ask for, and a 458 solid at 2100 to 2200 will penetrate at least a Sherman tank, and maybe a Nazi Panzer! much less a elephants head! shocker tu2

But IMO, the 416 and 404 is just as good and has been my preference over the years..


With A2230...no compression needed.

Ray, I have an old NRA American Rifleman that came out after Win introduced the 458 and they sent factory ammo to the HP White test lab to be chronographed and they reported it did reach velocities a little better than 2150 fps.

I think the issues were somewhere between what Jim Carmichael found, that the factory equipment was not very consistent and was underloading some rounds --- and maybe the fact that old ammo that had been sitting in the African sun might have degraded.

But with current powders like AA 2230 it is no problem getting 2200 fps with no compression . And Jack Lott wrote on numerous times that all he wanted was a 500 gr bullet at an honest 2150fps


Anyone who claims the 30-06 is ineffective has either not tried one, or is unwittingly commenting on their own marksmanship
