You definitely still need the rangefinder. :D
I still have a DOPE card, too, for more precise solutions when I have time, but quick DOPE out to 600 meters can be memorized for most loads.
Those that like to use the best, do. Those that are comfortable with old ways, don't bother switching, even though it's a better system with no real downsides (except for games like LRBR, where the availability of mrad scopes with turret increments smaller than 0.1 mrad are rarely available)...
I watched a hunter sail a bullet over a cow elk at 492 yards because his SFP Zeiss Conquest 3-9x RZ600 scope was set on ~6x instead of 9x. The elk ran off before he could figure out what happened.
I work in meters because I zero at 100 m with a cm-based grid, so 1 click corresponds to one square on my zero target. But otherwise, it doesn't matter at all which distance unit you use.
Where in AB are you located?
I also did the Kentucky windage and BDC things for several years. Today's mrad-based scopes just provide the option of doing things more precisely while keeping it simple, but there's no reason you can't use them the same way you've always used your old scopes.
The benefits of mrad scopes and reticles go far beyond this relatively small RS crowd.
You will always prefer MOA until you spend time with an open mind and a mrad system. Seen it too many times, including myself several years ago.
It's also far more effective to call the correction (where the spotter wants the next bullet to go), rather than calling where the miss went. Prevents confusion and tells the shooter what to do, rather than forcing the shooter to calculate what to do and then execute.
I have seen experienced people misjudge, or judge differently, the size of a distant object in inches more times than I can count. It's not a reliable system if you want to consistently hit things at several hundred yards/meters.
Of course, on a screen it's easy to casually round. But when you're in a stressful situation with lots to think about and execute flawlessly, simpler, even minutely, is advantageous.
Aside from having to round, the number of clicks should line up with the number you need to dial.
- 0.62 MOA ->...
Exactly. Use a visual scale that both spotter and shooter can relate to, rather than a number that is subjective to one's perception. 1/4 of the belly-to-back depth is much easier to coordinate between two people than what one person visualizes as 5" and the other visualizes as 10".
The primary advantage of mrad or MOA is in the actual use, not the numbers nor the theory, which is why I asked. If you've never worked much with MOA, you won't fully appreciate the difference, as minor as it may be.
We'd get along fine. I've got a couple of degrees in physics and also have...
LOL, it’s knowing that what you’re seeing in your scope is actually 5” that’s the tricky part. No need to try and think in inches. Just see your miss and hold off to compensate. If your reticle has an angular ruler, you can measure the correction with that. The trouble comes when trying to mesh...
It’s not even about figuring drop in your head. Even if both shooters need to look at their DOPE, base-10 is easier to manage.
If your DOPE says 6.43 MOA, you’re going to dial to “6” and then think “how many 1/4 MOA clicks is 0.43?” You’ll then round up to 0.5 and dial two more clicks. If your...
