I will be mounting a bushnell 4200 tactical 6-24X50 on my savage fp 308
I want to keep a 100y zero , but also shoot out to 800y+ . Will a 20moa base alow me to keep a 100y zero ? I beleive there are 43-50moa on these scopes , can someone send me the right way ?
 
The Bushnell 6-24 on a 20 MOA base on a 308 will zero at 100, but won't get you to 800 (at least the ones I own don't, runs out of "come-ups" about 20" short at 700 meters). It has to do with the 1/8 MOA adjustments within the scope. The 8-32 does the same thing. I'm currently looking for something with a lot more adjustment, with roughly the same magnification and lense quality, which means mucho dinero, sadly. - dan
 
That scope will not have the elevation to do what you need it to do. You will be good out to 600m though. It is possible to make the shots out further using Mil holdover, but is not as precise as using the turrets.
 
Sorry guys but this is a new scope and has more then enough elevation to make the trip. 30mm tube and 45 to 50mins. Should have been more but that is Bushnell.

Put it on a MOA base using Burris sig rings w/inserts. Shoot it and zero the rifle. From there, see how much more up you have. If you have 30mins or more of up, you are good to go. If not, just shim the scope with the included inserts and rezero.

Example, right now you have a 100yd zero and you have 25mins of up left. Shim the scope with one 10min insert or you can use both front and rear and center the windage too. Simple.

A 308 will only need 32 to 38min to go from 100 to 1000yds.

Nice scope. Waiting for mine to arrive...

PS there is a link in my sig line to help you set up your optics for LR shooting.
 
Now I'm messed UP!

I found this question interesting so I decided to crunch the numbers and see if it would work but did not get a chance to reply before Dan's post. Even though I do not have one of these scopes myself I was going to recommend that it would work just fine. Because Dan actually has one of these scopes and a 20 MOA base I believe what he says is true but I don't understand why. Maybe someone can help me see what mistake I am making trying to figure this out.

If this is the scope being used http://www.bushnell.com/general/riflescopes_elite4200_42-6245t.cfm
Then according to Bushnell it has a 50 MOA (or 50" at 100yds) range in .25" click adjustments.
A bullet with a .4 ballistic coefficient going around 2700 fps (lower than standard for a .308win) will have approximately 40MOA drop at 1000yds with a 100yrd zero.
If what I assume is correct when mounted properly the scope should sit at the middle of its range which would leave 25MOA adjustment for bullet drop. If you mount it on a base that adds 20MOA then you should have 45MOA which would be adequate out to around 1050 yards.

If I am doing this all wrong please help me see the light.

Thanks

Dave

By the way this scope looks like a good contender for budget LR tactical style glass. Nearly half the price of the equivalent Leupold, (not that I'd compare the two based on quality) but if it is anything like the Bushnell 10X tactical I would give it a try. Let us know how you like it and if it tracks well.
 
Looks like I just missed your post Jerry. I guess I'm not so messed up after all.

Thanks

I think I'll order myself one of these scopes aswell.
 
I know many will not like this but the Elite 4200 and soon to be released 6500 have equal or better glass then the upper end Leupolds. The same factory that produces glass for Nightforce and other big budget scopes makes the lenses for THIS line of Bushnells.

I will test this scope brutally when I get it but all the other scopes I have used have worked 100%.

Nikon is another top line brand that gets some press in the US. Very nice glass, great mechanicals and a bit more money then the Elites.

Neither brand is plagued by the mechanical issues of the Leupold Side focus adjustments.

Dave42, your math is right on. The only difference is when you are shimming scopes, the zero's don't always work out exactly because of what the scope 'sees' - relation to bore line, etc. Which is why I say install the scope, shoot it to find out where it is, then adjust accordingly. It might take a few tries to get it shimmed right.

The Bushnell Elite 4200's have been cursed by limited elevation adjustment for decades. Yes, we all have #####ed as loudly as we could. Bushnell has been very slow to respond.

The big advantage is that the ENTIRE adjustment range is useable. It neither sticks or looses visual accuity at the extremes of movement - common in some high value adj scopes.

So if your scope only has 30min of adj, you can use the full 30 min. Some scopes that rate as 50min might only have a true useable range of 40ish.

I am looking forward to this scope as it is the only 4200 series I haven't played with yet.

It may be possible to actually bottom out the scope to get the 100 m zero, I have never tried to get that far up on the tube. In my past experience on the rifles I own and use, with a 20 MOA base you are usually at 20-25 MOA on the scope at 100m. However when you get out to 800m and it is windy you have already put 22.5 MOA on again to get there, how much windage adjustment do you have before you have bottomed out the reticle on the tube? Will there be enough to shoot in a 15mph wind? I don't know as I have never had a scope with that little adjustment. I will defer to Jerry, If he's sure it will work I believe him.
 
Anyone have a source for this scope? I can find plenty of US websites selling it, but I doubt they will ship to Canada...
 
All the usual suspects that carry Bushnell Elite 4200 scopes should carry this. Hard to come by as demand has greatly exceeded supply.

Higginson powder was asking $700 the last time I talked to them.

Thanks! Higginson powder happens to be right in my backyard, I didn't realize they sell Bushnell. I'll give them a call, maybe I can save shipping charges.
