We surely don’t want these weapons of war coming across the ocean like the disposed Afghans surely will and through the porous border.  We need gun control – now!

Maybe this was all planned.  Maybe somebody is trying to cover their tracks by handing over weapons technology that ultimately ends up in the hands of Iran, Pakistan and China.

Maybe.

Some of you will say “I told you so” concerning the brilliance of the 6.5 Grendel when we’ve discussed this in the past.  But one nice thing about this cartridge is that an upper swap combined with another magazine gives you another rifle.  Buying a 6.5 Creedmoor rifle, for example, means switching to a completely different rifle, i.e., an AR-10 rather than an AR-15, with all of its recoil, weight and nonstandard parts lists.

There is this recent article from Recoil.  Here is a fairly recent video.  AR15.com does a gell test with the 6.5 Grendel.

And finally, near the end of last year, Ryan Muckenhirn did a very good discussion of the cartridge.

Anyway, it seems like a good upper to have, as well as a legitimate White Tail cartridge. It didn’t seem to catch on as fast as the 6.5 Creedmoor, but it wasn’t a “flash in the pan” either.

If the other two goobers would shut up, this would have been an absolutely great video.  I could listen to Ryan teach me for hours.  The two goobers made it just a great video.

Buffalo Bore makes this round hot.

I do wish that Henry would make a Walnut furniture rifle in .454 Casull.  The alternative is an absolutely beautiful rifle by Big Horn Armory.

But their price is too steep for me.

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.
