Hi All.

 I am considering one of the Burris Xtreme tacticals for my M1A.  Does anybody have any experience with their ballistic mil-dot who might be able to give me an idea of how well it works with the .308 for hold over points etc.?

Are they a good idea or is it better to stay with the standard mil-dot.  The ball mil-dot is obvioulsy a combo.

thanks in advance for the help

The ballistic mil-dot was designed for a std. factory 55 gr. 22-250 load out to 500 yds. +, but like any ballistic reticle it's probably gonna require manipulating the system to make a "better trajectory fit", and it probably won't be a perfect fit (at even 50 or 100 yd. intervals). The Burris Tech. Notes actually provide some general data for zeroing the reticle with some 308 load. Read the Tech. Notes for their ballistic reticles, as they have some excellent info on manipulating zeros.


My 6-24X BMD is calibrated for about 16X, but i like high magnification for long-range shooting, so i simply recalibrated it for 24X, and it's working fine on a 6AI coyote rifle using the 87 Hor. BTHP @ 3550 mv. That reticle is a good one, and the fact that it's in a second focal plane scope means that it can be really calibrated for any magnification that suits your needs-- tons of flexibility.


At 24X the reticle subtensions (including mil-dot) are 45.5% of advertised.

Good choice of scopes, I'm sure you will enjoy it.  I will say that the big problem with putting any scope on an M1a is the lack of a proper cheekpiece.  McMillan has a new stock that will solve the problem but you are talking some serious money for it. You will find that the scope base that attaches to the side of the reciever must be fitted by a gunsmith.  As for Balistic plex that will work just fine for holdover on quick shots the marks are constant so point of imapact at specific distances is repeatable all you have to do is spend time on the range to determine what mark lines up with what distance for the specific cartridge you use.  When you have more time to set up your shot you can dial in the correction using the tactical knobs. Practice practice practice.

The big problem is the lack of a proper cheekpiece there is so much distance needed you may have to ducktape a duck decoy on the stock to get a proper cheekweld. I went back to iron sights untill I can get the McMillan stock.
