I’m looking at tapered bases and can't seem to find a good source for picking one, my guess is there is no set in stone rule and your ballistics, optics and distance all have a say in how much taper to go with. My set up will be a .243 with MV around 3000 FPS,give or take 200), for the long shots I'll be tossing 107-115gr pills, my scope only has 50 MOA total height adjustment,200 1/4's) Ideally I would love a base that would work from 100-1000 but realistically it will see 6oo yards for its normal max. I know I'm asking for allot with such limited amount of adjustment, my gut tells me it is most likely impossible but if someone with more experience could steer me in the right direction I'd really appreciate it.
Tapered Base- How Much To Go With?

Using a tapered base or the Burris rings does not get you an 'extra 40 minutes' of elevation adjustment. If only it was that easy. A scope with 50 minutes of total adjustment will always have 50 minutes. A tapered base simply moves the center of adjustment farther down range.

It's possible to have a scope that can be adjusted for any distance between 100 and 1000 yards. 50 minutes of adjustment would get you there. The ideal set-up would be a tapered base or rings that would allow an optically centered crosshair to be at the point mid-way in the trajectory. Even then you'll be near the bottom of the optical center at long distance and the top of the center at short distance. ,Or maybe it's vice-versa??)

xpfuzz said:Either/OR,,it works..I know it doesn`t give you MORE adjustment in your scope,,BUT,your 40 minutes closer to what ya want..and I know your not in the optical center,,but with a good scope,,does it really matter..My Sightrons don`t seem to mind one bit...

An 'extra 40 minutes' were your words, not mine. And if it gets you 'closer to what ya want', which is 1000 yards, it will get you farther from the other end, 100 yards. It works both ways.
Optical center does matter. Not only do extreme elevation adjustments distort the optics they also affect windage adjustments. At 1000 yards you're going to be at one of those extremes and that's exactly when you'll be needing precise adjustments.
I know there are scopes that can accomodate adjustments from 100 to 1000 yards. But just because they can do it doesn't mean it's the best way. I shoot long range Benchrest. You'll see a lot of $1500 scopes on the line and most of them will be mounted on tapered bases or rings. There's a reason we do it that way.

I hope you're still there. We have kinda ignored your original post. That's what happens when guys start talking about guns and shooting.
I shoot Benchrest. Everything from 100 to 1000 yards. I learned long ago that it's difficult to have one rifle for all things. Maybe I'm just using it as an excuse to have more guns but I don't try to extend a 100 yard rifle to shoot 1000 yards, and vice-versa.
600 yards requires between 10 and 15 minutes of elevation adjustment and most any scope can handle that without tapered bases or rings. And, it can be done with most any cartridge too. I shoot a 6PPC at everything from 100 to 600. Your 243 will work just fine too.
I would suggest to you that you treat 1000 yard shooting as a completely seperate discipline. If you want to shoot that distance, try to buy or build a rifle that's set up exclusively for it. Don't abuse your scope by cranking the knobs back and forth over the entire range of adjustment. You're just asking for something bad to happen eventually. I've also noticed that many shooters will go to great lengths to accomodate 1000 shooting, try it once but never do it again. It's a looooong way.
If you're looking for a compromise that will extend your range beyond 600 yards, get a 20 MOA base. You'll have to use most of it to get back to 100 yards and your scope will still be reasonably centered optically. A set of Burris rings would be even better because you can use the inserts that give you 10 MOA or so, which I think would be an even better compromise.
JMHO. Good Luck
