Hey guys I'm new here and totally new to long range shooting (so be gentle, lol). I have a Remington 700 30.06 and I'm about to mount a Leupold Mark 4 LR/T to it but I wasn't sure whether or not I should use the standard rings (a standard Leupold base came with the rifle so that was nice - I would just need high rings) or a 20 MOA base. I understand that a 20 MOA base will help me shoot at longer distances but would this interfere with shooting at closer ranges (say under 500 yards)? Also with the 50mm objective would a 20 MOA base cause the scope to sit up too high beyond any point of comfort?

I use a 20MOA base on my 700 with a Vortex Viper 6.5-20x50 in a set of low rings and it works great. I do use an eagle cheek rest with the factory stock. Whether you need the 20MOA base will depend on your optic and the ranges you intend to shoot. It should not impede your shooting at 100-200 yards.
Thanks for the good info John - when you say it will depend on my optic what factors will it depend on that I will need to consider? Also will a 20 MOA pic. base help me better adjust my eye relief? I have the factory stock still and I could already tell that I will need a riser.
The biggest issue is how much elevation your scope has. Pretty much any scope that is useful for long range shooting will work fine with a 20MOA base. Some scopes have enough elevation built in and you won't need any extra elevation to go to 1000yds. The extra 20moa the base provides won't hurt though. A one piece rail does give you a little more room to adjust the scope back and forth, but not a whole lot.
What scope are you planning on using?

Did you mean 70MOA of total adjustment? If so, with a 0 MOA base you will have ~35MOA of useable travel. If you put in a 20MOA base you will have around 55MOA of useable travel. I would use a 20 MOA base.
Scopes generally come from the factory with their turrets centered within their total range of adjustment. If a scope is advertised as 70 MOA of adjustment it will normally have 35MOA available in each direction (up and down). When you zero the rifle (on a regular base with no cant) you normally don't adjust it very much off of center - maybe a couple MOA. More than that would indicate an issue with the scope/rings/base/rifle. A canted base allows you to use more of the adjustment because your 100 or 200 yard zero is roughly 20 MOA higher than it would have been.
A while back I picked up a movie from Magpul called the art of the precision rifle. It has a lot of good tips and knowledge in there.
