Leupold Mark 4 LR/T M1 on my .308 I know I have enough adjustment on my badger 20 MOA base but I want my scope to sit lower closer to the barrel one a leupold one piece mount without the 20 MOA base will I have enough travel to reach a grand? Or will I need to go with a M3.

Re: Do I have enough elevation travel?
You will need to describe the scope that you have. The 10x and 16x Mark 4s will do it, but not some of the variables with higher magnification.

Re: Do I have enough elevation travel?
The M1 and M3 have the same amount of internal travel, 65 MOA. So that is 32.5 MOA of up and down and with your 20 MOA base it shifts it so it's 52.5 MOA up and 12.5 MOA down. 52.5 MOA is enough to get you to 1000 and a little farther with a .308.

Re: Do I have enough elevation travel?
You lose about 5 MOA by zeroing at 100 yards, so it is 46-47 MOA of up elevation with a 20 MOA base. Without the base, it's only 26-27 MOA - not enuff for 308Win.

Re: Do I have enough elevation travel?
SO how much MOA does the scope have of up and down travel and windage? I just wanted to throw on a one piece mount that keeps the scope lower to the barrel.

Re: Do I have enough elevation travel?
hey, i just asked about my scope and zero base in another thread. i have 90 MOA travel. thats 45 up and down. i was told thats just enough to get me to 1000 and i may not have alot of windage at that range. hope that helps you

If 1K is in your future keep the Badger 20moa base and get lower rings..........

Re: Do I have enough elevation travel?
I have shot 1k before and I shoot out to 800 on a regular basis I also just wanted to know exactly what MOA of up and down travel I have and windage lets say the MOA travel I have for up and down also counts for windage so if I am almost maxed out on elevation I wont have much windage? I have Mk4 low rings...

Re: Do I have enough elevation travel?
i cant answer that exactly, but i got the MOA adjustment off my scopes website, Millett. its 90 MOA. you should be able to find out online what yours is. if you think about scope design, you have a tube in a tube. move the inner tube up toward the top of the outter tube. now when its maxed out and closer to the top, it has less room to move left and right. and i may be wrong about anything i say, ill admit that. but im right alot too.
and thanks, i stole her from someone here i think. feel free to do the same. i think she is dropping it like its hot, as the kids say now days

Re: Do I have enough elevation travel?
Hello guys
to help out here a little. Scope movements are within a range of the inter tube, a 30mm tube will move more then a 1" tube. Even though there is clicks on the turret you may be at the end of the travel and there is no adjustment left or worse, there is not an enough spring tension to hold the adjustments for zero.
As you get to the end of the elevation there is less windage adjustment left. The most accurate area is in the middle of the range of windage and elevation.
Remember measurement of the clicks times the range gives you the value for each click at the range. 1/4moa X 550 yards= 1.375moa
for most modern cartridges you will need about 400moa+ at 1000 yards roughly. thats 40 moa at 100 yards. thats after you have zeroed your sight. If you need more adjustment use a 20MOA rail that will give you more up adjustment.
I hope this is of some help.
Good shooting

Ummm, don't you mean 1/4moa at 550 yards is roughly 1.375 (actually closer to 1.44, but who's counting) inches, not moa? And 400moa to get a cartridge to 1000 yards is a bit much, I believe you mean inches of drop again. 400moa at 1000 ia 400 moa at 100, is 400 moa at 50 is 400moa at 800, etc-moa is moa and is an angular constant.
This is a great example of why folks need to think in angular measurements, and not get wrapped arounf the axle over conversion to linear measurement.

Re: Do I have enough elevation travel?
Hello
to clear up the math. 1 moa = 1.047 inches at 100 yards. so if you are at 550 yards 1/4 click if the click is moa 1.44 inches or 1.375 moa. so we are both right its just how you measure it.
Most shooters use inches, I am getting where I like .1 mil clicks as its easy to work and works for yards and meters.
As to the drop, if we have a 308 with 168 BTHP at 2650 fps sighted in at 100 yrds we will have a drop of about 440 inches or 420 moa. so I think looking at the math a little more is valuable.

Sorry Steve, but a drop of 420 inches at 550 yards is not 420moa. 420 moa is 438.35" at 100 yards, and 2410.94" at 550. A 420" drop at 550 yards is 72.92 moa which is way more than a 308 at that weight and speed needs. Actually, running it backwards, the drop at 550 for my 308 is 73.83", so moa needed for adjustment would be inches of drop divided by yards (in hundreds) times .955 (73.83"/5.5)X.955=12.82moa.
Looking at the math is definately valuable, and once again this is a really great example of how easy it is to get wrapped around an axle......

Re: Do I have enough elevation travel?
But its not 420moa.......440 inches at 1000yds is-
(440"/10)x.955=42moa, you are leaving out the part about dividing the inches by yards (in hundreds) to convert to moa.
Just trying to keep it clear for the folks learning, I'm not trying to bust your chops-I know something's just not making it from the noodle to the keyboard
