[QUOTE="AJ Peacock, post: 141171, member: 4885"] There are a lot of unknowns here, but I'll give you some ideas. Assuming a 24" barrel you'll get around 3200fps maximum for a 165gr Nosler Accubond. This bullet has a BC of .475 Your combination of 20MOA base and 38MOA adjustment range makes for a total of 58MOA vertical adjustment, BUT some of that is going to be used up in getting on a zero. Assuming that the scope would be about centered for a 100yd zero without the base (means that 19MOA is going to be used for a 100yd zero) giving you 39MOA vertical travel for 'reaching out there' (20MOA base + 1/2 of the scope travel). For a 100yd zero, you will need around : 15MOA for 750yds, 25MOA for 1000yds, 39MOA for 1250yds. Now I've made some pretty mighty assumptions that could be erring for or against you. For example, if the 165gr bullet you are using is a Hornady Spire point Interlock with a BC of only .387, you'll get almost to 1150 yds with 40MOA. If you have a 28" barrel, you can get to 3300fps, which lets you get to 1300yds with 39MOA. But then again, maybe after you have sighted in, you have more than 39MOA left, or perhaps less? Fill in a few of the details and we can help you a little more. BTW: welcome to the forum. Don [/QUOTE]
