Since I hunt with, and spend a good portion of my day laser etching custom turrets, you can guess that I feel they are a great LRH tool.
That said, MontanaRifleman's point that a single turret can't match every situation is valid. Regardless of what system you use, you need to know what your bullet will be doing in the particular shot situation. If we find ourselves in a situation where an extreme elevation, temp, or angle means the turret won't be correct, we adjust accordingly. Adding a minute or taking a minute off with our turret is just as easy as it is with any turret.
The advantage is that for 80% - 90% of the shots we encounter, we can just dial and shoot if our turret is within about 3000' of where we are hunting. That window can be smaller or larger depending on your loads performance. With a few simple "rule of thumb" formulas we can cover the other shots very reliably.
With 2 turrets you can cover a lot of North American hunts and you can be sheep hunting at 10,000' in the morning and in less than a minute put your second turret on and be dead on for a 3000' antelope hunt. We hunt WY, CO, & NM for the bulk of our hunts which generally takes us from 4,000' to 11,000' and we use a 7,000' dial for about everything in the west..
Second turret is free for LRH members this month and you always get a click or MOA (special request) dial with the scope that works great for load developement.
Answered your post in another thread to avoid hijacking this one
So what you are saying is if I had a turret set for X rifle with X load at 7,000 feet, it would be good from 4,000 feet to 10,000 feet due to the aforementioned 3000' range? Do I have that correct?
Sorry guys - totally new to all of this so I may be asking some rather simple questions that most of you understand already.
At 1000 yds your difference in drop from 7000' to 4000' would be about 12-20 inches depending on the ballitcs of your bullet. At 600 yd it would only be about 2-4 inches. This is due to the difference in air density and the resultant drag difference.
I have asked a similar question in the other thread I started before I saw you ask this one.
It's not that simplistic, but in general that is correct for a high performance load (high BC bullet going fast). If you throw multiple variables in like severe angle, big temp swing and extreme range, that window gets smaller. An individual load's specific performance has a huge effect on how far you can be from your dials specs before needing to manually adjust.
As stated earlier in this thread, anyone interested in hitting stuff way out there would be ahead by accessing a ballistic program and playing with all sorts of variables to get a feel for what changing the variables does to bullet flight.
We were hunting antelope at 4000' 80deg last week. Our 7000' 30 dial was 1 click (1/3 MOA) different at 1000 yards. If we would have had a cold snap and it was 4000' 0deg, we would be adding clicks at 1000 but would still dial directly to the yardage at 500.
I'm still trying to figure out how this is possible!
Super hot load I imagine, I guess you shoot virgin brass everytime, LOL!
Nope, not hot at all as far as I could tell. At 1/2 grain higher I got a slight stiff bolt. Norma brass and they've been fired 1-4 times. Taht RL 17 seems to like 180 E-Tips in my rifle. The 168 TTSX's were a good bit slower.
