Ive got an SPS .308, 20" factory barrel, Warne one piece mounting rail (picatinny), Night Force Med. rings with a Vortex PST sitting on top. Ive shot long range in the past, but nothing to the extent of what I have in mind for this rifle (1,000+). I have some background in shooting (USMC 0331), that said, I understand the fundamentals and have a general grasp on marksmanship. Some guy at the local shop told me that I wouldn't be able to reach anything past 850 yds, This sounds like complete bullshit considering I have approx 72 MOA in the scope. I'm shooting a 168gr BTHP, DOPE for 1,000 yds is 45 1/2 MOA. Is a 20 MOA base necessary for what I'm expecting, or is the job feasible with my current setup?

Thanks for any input!

Well devil, as you know..... When it comes to gear, it's better to have it and not use it then not have it when you need it.... I have a 20 MOA Nightforce base and I don't shoot past 500 yards at the moment... But I got it anyway....

I have both a Zero and a 20 MOA base that I swap back and forth based on the majority of my shooting at the time. Both bases have been bedded and I have data for each base. When I swap I just make the changes necessary on elevation and windage turrets, move the turrets to zero and shoot away. Changing back I just reverse the process.

I like to change because having the scope "centered" allows you to use the best part of it's optics. With a 20 MOA base, shooting at under 500 yards, the elevation is cranked Down to the point where it could limit windage adjustment.

With my setup, and a torque wrench, it's only a matter of a few minutes to change the base and then fire a round or two to verify "zero".


Barrett offers a neat option. A set of rings that have a pin and pivot setup so you can have 15 MOA (more useful for most) and 40 MOA (for the really long ranges). Loosen, move the pin, re-torque, Bobs your Uncle, and you are adjusted the exact amount for the pin position. Pricey though. About $225 for the set.
