what scope for m99 barrett to get to at least 2k yards?

[stukpedal]

My M99 has a 27 moa rail, it's a few years old, but I assume the new ones would be the same. I have a Leupold mk4 w/a BORS, and I can shoot from 100yds (zero for the BORS) to 1600 yards (50 BMG). I'm sure it will go further, but 1600 is the furthest I have access to. I have no idea how much further though.

Trying to resolve the same problem. I use a 12-50 S&B but at 2400 yds need 75 moa and only have 65. Use 3mil hold. New S&B 25 has moa range of about 115 moa but not powerful enough. Also at those ranges mils spacing is too coarse. Looking at ior terminator 12-52 but would prefer not to have sfp. Anybody using ior 12-52.

I'm with R.C.Saul on this one 76 MOA ..... Your real drop will come betwee 1700 yards and 2000 yards. With it set up the way you've stated at 1700 yards your drop should be about 976" inches and vel's should be 1250 fps. when you reach 2000 yards you've dropped something like 1595 inches with your vel's at 1100 fps... that give you a 619" inch drop between 1700 & 2000 yards.
From the way it sounds you should have about 70 MOA in your scope now without the 27 MOA rail mount. How high are you above the bore?
Head out to 2500 yards and it really gets ugly.

It does have a 27 moa rail on top. I'm thinking nightforce 8-32 with a set of Barrett rings that give more moa.

[alcesgigas]

Would a Near Alphamount with 20moa base and 20moa rings get you there?
