20MOA bases too much?

I have just put in an order for bases, rings and scope for my new rifle, .308win HS Precision HTR.

A friend just warned me that 20MOA bases are used for 100yd shooting and may not let me shoot down to and under 100m.

Is this true?

I am waiting on a quote for the shipping so I could still change the order if need be.

Re: 20MOA bases too much?

20 moa bases are typically used for shooting 1000yds while keeping the reticle optically centered (or there abouts) in the scope tube.
If you do not intend on shooting very long distances with the .308 than I do not see any advantage to these bases. Most of the tapered bases are fairly tall so they may raise your scope height more than you expect. However, lower rings may work with the taller bases and still give acceptable height.

I have 20 moa bases on rifles that have been shot at 100yds but this is certainly not ideal and may not work with scopes that have minimal verticle adjustment. Not sure on this though.

Re: 20MOA bases too much?

If you plan on shooting to 1000yds you will need the 20MOA bases. My Rem. PSS 308 has a Badger 20 MOA Rail and I have no problem shooting at 100yds. The Tasco SS 16X has 100 min. of adjustment and I'm 41min. up from the bottom at 100yds. If you only plan to shoot to 600yds I don't think it would be needed but you never know, you might get the itch to shoot farther and then you won't have the adjustment you need.

Re: 20MOA bases too much?

Most of the shooting I will be doing will be at 300meters at my local range and around 500m at home where I have more space to stretch out.

That said, it It will be some shooting at 100m and when I'm hunting you often get shots a lot different to what you hoped for.

Exactly what inconveniences will 20MOA bases give me if I didn't need them? Will the aiming point be somewhere in the other half of the scope for shooting at 100m? 300m?

The scope is a Nightforce NF 8 - 32 x 56 which has 50MOA of internal adjustment availiable.
The rings and bases are going to be Baer 30mm steel rings and a Baer base.

Otherwise, can someone give me an idea of what sort of base to go with? Considering that for now, most of the shooting will be in the 500m range with shooting at 1000m is something I want to do, I never have done anything at that range yet.

I was hoping to put up a big metal gong and just see if I can hit it... [img]images/icons/wink.gif[/img]

I have an 8x32 nxs also and it has 65moa adjustment(62moa acutall). If you only have 50 i would tend to think that something is wrong with the scope. I would double check and if you only have 50moa i would call nightforce and talk to them about it.

Re: 20MOA bases too much?

Ok, sorry if I seem to be a bit slow to understand this...

I just spoke to the helpful woman at Brunoshooters supply about getting me a 1 piece base instead of a 2Pc since that is all they advertise on their site.

She will probably contact Nightforce and get one of their 1Pc bases which are still 20MOA.

To be more direct:

Zeroed at 100m, will the reticle appear to be out of center?

What about a 300m zero and a 500m zero?

Matt: 50MOA of adjustment is what they say the scope should have on the Nightforce site, for an NF series scope, not the NXS.

Re: 20MOA bases too much?

The reticle will not "appear" out of center, regardless of the base you use. It will always appear to be centered to your eye, even at the end of the adjustments. The problem arises when you either cannot zero because you don't have enough internal adjustment, or you can zero at 100m with your elevation knob, but you cannot zero the windage because the extreme elevation adjustment has used all of your windage adjustment. Imagine a tube inside a tube; this is how the scope erector system works.
