We could all be in a rain storm so optic performance when wet should be an issue of concern.

And brrrr and brrrr and brrrr …

On an FFP the reticle expands or contracts in conjunction with the magnification, allowing the gradations of the reticle design, whether milliradian (mil), minute of angle (m.o.a.) or bullet drop compensating (BDC) to remain proportional. With the high range of magnification possible on today’s optics, it is a true luxury to crank the power to whatever is ideal for the level of support, the field of view desired and the precision of shot placement, then simply hold on the correct reticle gradation for the range and begin to press the trigger.

Most AR shooting, in whichever role—whether sporting, competition or duty/defense—is done within the “sweet spot” of the .223 Rem. trajectory where the shooter can simply hold on the intended target and get the hit. With the common 50-yd./200-yd. zero the bullet’s path is within the margin of error out to about 250 yds. This lets a shooter enjoy a consistent reticle image that remains the same, regardless of the magnification, and is still bold and visible at the low end.

However, if the shooter has to hold over for the occasional long shot with the magnification topped off at the maximum, the reticle holds are “true.” Six power is a good compromise for visibility at distance but is still low enough that many shooters can use maximum power from an unsteady support without getting motion sick from the image and, thus, prone to snatching the shot off.

I think this is a pretty good article, explaining what you’re giving up with each choice.  For FFP scopes and high powered rifles, the reticle adjusts according to magnification.  This lets the shooter more accurately judge holdovers with extreme distance and magnification.

But that reticle looks mighty small on low power.  For SFP scopes, there is no need to go to high magnification to make accurate judgments of holdovers because the reticle is always the same size.  But for extreme long range shooting (as long as you can get with an AR), that reticle won’t adjust with magnification.

Again, I think this is an informative article.

Each one of these guns is high $$$.  I guess you have to be a YouTuber to be able to afford them.

Saying you dislike heavy recoil is kind of like saying you can’t drive a manual transmission. Everyone likes to say they aren’t bothered by recoil. Everyone lies. I know shooters who boast of their recoil tolerance but when I see them at the range they have 50 lbs. of lead stacked behind the rifle.

Fool me all you want, but don’t fool yourself. If you really want to find out, have a friend at the range load the rifle for you, leaving the chamber empty on occasion so you never know if the rifle is going to fire or not. When the firing pin clicks on an empty chamber after a string of live rounds, you’ll know. If you really can handle it the sight picture will remain steady. If not … I’ve seen people with both eyes closed, face pulled away from the stock and contorted in a grimace. If shooting offhand sometimes they’ll actually stumble forward a step or two.

I always look for the gun which can supply the minimum recoil and still get the job done I am asking it to.  There is no virtue in unneeded recoil.

I could have done with some narration and without the music, but it’s still an interesting video.

Shooting Illustrated.

Footprint A will fit the Trijicon RMR Type 2, Holosun 507CX2, and Trijicon SRO reflex sights. Footprint or slide cut B fits the Shield RMSc, the SIG Sauer Romeo 0, and the Holosun 507KX2.

Footprint C works for the Leupold Delta Pro, SIG Sauer Romeo 1, and the Crimson Trace CTS-1250. Slide cut D will fit the Burris Fast Fire and the 2 Vortex Venom. And finally, like with the new Trijicon RMRcc and Vortex Viper, some reflex sights have their own unique footprint.

That’s a quick summary.  Of course, if you want the details, this is the authority.
