What scope are you using that doesn't allow you to change BTs? If it is BRs then they are different for every load and condition anyway.
For my shooting, at least out to 1000 yards, I agree that BDC turrets are easier and faster than dialing MOA especially in lower light. I have gone almost exclusively to adding BDC knobs to my hunting scopes, and have experienced no trade off in precision once you understand correction adjustments if needed. Since I started hunting at the longer ranges the biggest issue I have had to deal with is having enough time to get the shot off at the animal. For me a BDC is absolutely faster which allows me to use the time for determining other variables such as wind, etc.

Re: For you MK 4 guys.

Bullet drop compensating turrets have been around for decades. It has just now gotten to be popular, or a fad whatever you wanna call it. The Leupold CDS is just the same system as on the original 10x Ultras the Army has issued since 1988, just without the covers (I believe). Ours don't match the rounds we were issued, they have changed since the system was designed. However, the turrets are faster to me as well. You just gotta know the different adjustments. Just going off my memory and not looking at my data book, I know that under certain conditions my drop at 900 is 8+2. Turn to 8 then two more clicks (moa). The problem with this is that if you are using a ballistic calculator like Exbal, it doesn't facilitate for BDC turrets (none that I know of). There may be a system I don't know about. Maybe Gunwerks does? We just have to keep detailed written data for different conditions. The 3.5-10 Leupolds we run on the M110 have both a BDC and MOA markings, but it is mass produced and may not match 100% with that particular weapon. I like this idea if it matched that particular rifle and out then only out to medium ranges. Then you have the best of both worlds.

Re: For you MK 4 guys.

Thanks for the dicussion guys if you have more opinions please keep them coming. So what power do you all recomend. I was thinking 6.5 x 20 but maybe that is too much.

So if what I'm reading is right-- I could order a scope from leupold. I was thinkin MK 4 6.5 x 20 LR/T and sight in dead on at 200. Then use a Ballistics program with a certain load to figure out how many clicks for a certain distance. Then hold dead on? Sorry if I seem dumb.......If it matters this gun will be used for coyote hunting 95% of the time. IT also has a Lilja with a 1:8 twist.

Re: For you MK 4 guys.

Go right to the 8.5x25, get the Alumina flip-ups, and the reticle you prefer, delivered straight from the custom shop(that way human hands & eyes have visited it).
Leupold Mark 4 8.5-25x50 LR/T M1 Long Range Tactical Riflescopes Personalized by Leupold Custom Shop FREE S&H 54690, 60070. Leupold Mark 4 Riflescopes, Leupold Riflescopes.

Forget Leupold bases/rings. They're too heavy.

Re: For you MK 4 guys.

I would go with the M1 dials all the way. 1/4 min adjustments are going to be more precise than the popular 1/3 min BDC turrets. And like MIkeCR stated, they are affected by altitude, and different loads. Some research will separate the fact from the fiction found in this thread.

*MikeCR, I commend your tongue holding ability.
