Has anyone had personal experience specifically using a 6.8 SPC with the Nikon BDC in the Monarch or similar top line Nikon scopes?



If so...which scale was most appropriate for your 6.8 bullet weight/loading and did you find the graduations to be a reasonable match to the 6.8 trajectory?

Thanks.

A friend of mine bought one about 4-5 months ago, I mounted and zeroed it. His however is on a light weight 5.56 AR, zeroed at 100yds., if I remember correctly the 200yd. stadia was just a tad high at 200, with 55gr. bullets. He'll be out at my range with it this comeing Sat. I'll shoot it again to confirm my rather vague memory. Hope that helps, or gives you some idea of the BDC graduations.

Kerry, do what J.Boyette posted on a different post.

What I do is this. Take a yard stick @ 100yds. Line up the BDC reticle on the yard stick. Where ever the BDC marks line up at, like the first one on 2" line, the 2nd at 4" and so on, that gives you the IPHY bullet drop, plug it in a ballistic program match it up as good as you can. ...

I was just about to post how to measure this then I read the WHOLE POSTING :D

Keep in mind that inch drop is almost the same as MOA. Just a little off out to 500yds, after that, it gets WAY off.

So if you have your DOPE sheet for your 6.8 SPC loading, and you place the yard stick down range you can figure it out real fast.

One more thing,

This want I found out

first circle = 2 inches
second circle = 4.5 inches
third circle = 7 inches
fourth circle = 11 inches

So that works out to be with a 100yd ZERO as the following TMOA drop.

first circle = 1.91 TMOA
second circle = 4.29 TMOA
third circle = 6.68 TMOA
fourth circle = 10.50 TMOA

So running the following ammunition, this is what I have

One last thing before I kill your hopes here. It's a SFP optic, so the BDC only works on its highest mag setting. On a good note, I would run a 250yd ZERO and not worry so much. That way you can run PBZ from 0-250yds, and not worry of the mag setting, then go down range and use holds. That might work you know?

Let me run these numbers:

I ran the 3-12 on my 308 for hunting last year
it was on, zeroed at 100, 2 and 300 confirmed

I didn't like it when hunting though as the reticle was too cluttered for me when shooting in between, say at 250

I do think they are good scopes
