I don’t disagree with your post; I am curious what the “unquestionable dogma” is that you meant?
-scope optical quality doesn't matter (It's not that you teach that it doesn't matter, it's that people take what you teach and oversimplify it when they repeat it): it matters a ton on eastern whitetail in the last minute of shooting light on cloudy days, which is something I encounter about 50x more often than I drop a rifle.
-everyone needs a dead-on-at-100 zero: There's no reason to stop using some form of MPBR zero at all, especially for people who largely shoot inside of 500, and regardless of what ranges you expect to shoot at, there's simply no real downside to the 100-yard zero. If you're going from sea level to 10,000' with any modern caliber, the difference in 100-yard POI with, say, a 250-yard zero, is usually (much!) less than a single scope click at 100 yards. If you want to account for that, you can easily open up your ballistics app and fudge your zero range by a yard or five or whatever. This is simply math and people shouldn't be afraid of it. Besides, there's no guarantee that you'll have a 100-yard range to check zero. I've showed up to hunting places where there was a steel target hanging at 200 yards, or a public range where the best you could do was 80 (so you have to check your app and figure where you should be hitting anyway) or maybe the shortest realistic range was 150 (IIRC, last time, it was like 135 yards) or the place was crowded and there was a target hanging unshot at 200 and you could either shoot it or wait for the crowd to leave before you hung a proper 100 yard target.
-Mrads are superior to MOA: Neither is better or worse than the other. If you use one, you'll get more proficient with it, I'm sure, but being able to do 'speed hacks' with one system doesn't make it superior. You can very simply and easily do 'hacks' for both windage and elevation with either system that will work perfectly well in the 300 to 600 yard window where such hacks are feasible. At some point beyond maybe 600 yards, nobody should be using such 'hacks' in a sport hunting situation anyway. Take the time to compensate precisely as possible for everything, or don't shoot. I've seen you say that you've never seen a MOA shooter that can do his 'hacks' as fast as an MRAD shooter. That may be true but doesn't necessarily condemn the MOA system in general without knowing (or having a large sample of) exactly what system he's actually using or what his/their background is before they show up to your class. Also, if a guy gets hung up with MOA because he can't quickly round to the nearest 1/4moa....ehhh, he needs remedial math classes, not as simpler system.
-FFP vs SFP: I like FFP reticles but the ones made thus far generally SUCK in low light, which, again, is a problem in eastern whitetail hunting. I'd much rather have a SFP reticle that I could see at the last minute of legal light, and if you're using a scope that can be shot at max magnification on longer shots, it's no hindrance...which brings up a related issue:
-The teaching that people need to shoot on lower magnifications to spot their shots. This is a two-part problem. First, in eastern low light hunting, there are plenty of times where it's the last minute of light and you have to balance the need to *see* the target (which is almost dark) against the ability to maximize light transmission. Yes, there are times where you can dial magnification *higher than* the point where your exit pupil begins to get smaller, because being able to resolve the target a little bit better can be more important than maximum light transmission. I've had to dial to 8x or 10x to even *see* a deer well enough to make a shot at first/last light, and I'm talking about shots inside of 100 yards here - not long range. Either way, the deer might just be a dark blob, but a dark blob that I can place crosshairs on is better than a smaller but brighter blob that I can't resolve an aiming point on.
In fairness, I've also shot 500 yards with 4x. Sometimes that works fine. But I've killed a ton of deer that were very hard to see at first/last light. I've shot deer that were in thickets where I had to thread a bullet past a tree. I shot one on 16x once at maybe 75 yards. I could see a baseball sized opening and enough bits and pieces to figure out that the deer's neck was centered in that opening. Perfect hit, that I could not have made on 8x, even in good light.
In short, I'm not saying that 8x or so isn't sufficient for *most* shots, but there are exceptions. I think a lot of western guys miss these exceptions.
The second part of that involves shot-spotting. I submit to you that the vast majority of 'shot spotting' is a phenomena that happens when people are taking shots that they simply shouldn't be taking. That's not to say it isn't important or useful or even preferable to know exactly where you hit, but if people stuck with high-confidence shots (like 95% confidence of vital hit) it by and large simply wouldn't matter whether they saw the hit or not - nevermind that a whole, whole lot of 'shot spotting' involves seeing a hide-ripple that can be a bit misleading. I watched a video this week that looked like the guy (poster on this forum) hit really high. Later he shows the shot location, probably a full 3/4-1moa below where I thought it hit based on the video. In fairness, his video did give a good indication of his left/right error and I'll freely concede the importance of that in windy shooting. But at the end of the day shot-spotting is easy on a painted white steel plate but much more complex on an animal and can honestly be misleading. It should be valued, but not above all else at all costs - so there is a place for higher magnification. I'm not saying shooters need 16x for average close shots, and I can absolutely see where elk, especially in winter snow, could be quite easy to make hits on at 6x or 8x even at very long range. But it doesn't always work that way with eastern whitetails.
Again, I'm not saying there's no importance to knowing where you hit. What I'm saying is that there are times where it really does help to be able to see the target better and sometimes that requires magnification beyond what might be optimum for long-range shot spotting. And, again, if that's happening at a range where you're confident in the shot, whether you see the impact or not doesn't matter - the animal will be (or, should be) laying dead nearby.
In the interest of being fair here, shot-spotting helped me recover a deer once. I didn't see the hit but I filmed it and was able to confirm that she did the thing where she reared up on her hind legs at the shot like heart-shot critters do, then there was a flurry of deer activity in the field, then after they'd all scattered, one doe ran back through the field at a weird angle.....it was her. No blood trail. Heart shot below what I'd call good killing speed with a 6.8spc/110vmax, no exit, bullet lodged in off shoulder, she ran 100 yards and died, but I couldn't tell what direction she ran until I watched the video, and on the assumption that the last deer in the video was her, I walked right to her *after* I watched the video, after not finding her or her trail at first. So, yes, shot-spotting, or at least seeing the animal's reaction to the hit and direction of travel, can be very important, I'll concede - but it doesn't
always trump being able to resolve a small target.
Also, there have been lots of times over the years that I've shot deer where even if I'd been using a .22lr I couldn't have spotted the shot, as they were standing in tall CRP fields or standing corn or back a few feet or yards into a pine plantation full of briars. They simply vanish at the shot. Sometimes they're laying right where you last saw them. It's especially common with really fast calibers on close shots.
In short - I'm not saying shot spotting is not a good thing, but it isn't always of primal importance
I'm not saying 6x to 8x isn't sufficient for most shooting; I am saying there are narrow scenarios where more is better.
I'm not saying MOA is superior to MRAD; I am saying both are perfectly serviceable systems.
I'm not saying SFP is better than FFP. I'm saying both have strengths and weaknesses and while I think the biggest weakness of FFP could be fixed with proper reticle design, nobody has done it yet.
I'm not saying there's no value in a 100-yard zero. I'm simply saying that MPBR or some variant thereof has a lot of advantages in typical hunting scenarios for most of us.
I'm not saying that high end optics make up for scopes being unreliable. I am saying that there are 'passed the drop test' scopes I'd never buy because of their 'meh' glass. Glass quality does matter. Not always, but in low light, it really does matter, and there are absolutely scenarios where a scope that might not pass your drop tests but has shown to handle more normal use, with good glass, is of more value than a bulletproof scope with 'meh' glass.
