Grendel-Based 6mmAR for AR15s

Possibly a reasonable choice for getting into somewhat long-range (600 yards) target shooting.

6mmAR: AR-10 Performance from an AR-15
by Robert Whitley, www.6mmAR.com

" The 6mmAR is an easy cartridge to make, just run 6.5 Grendel brass through a 6mmAR full-length sizing die to neck it down to 6mm. (I had Redding make a special run of custom full-length dies that give .004″ tension on un-turned brass). Then load your cases and off you go to the range"

6mmAR Basics
Case: Derived from parent 6.5 Grendel case. Uses Lapua Brass, with small primer pocket and small flash hole. Case capacity is 36.0 grains of water

6mmAR Match Uppers
Complete match rifle uppers (with 6mmAR bolt), ready to attach to your lower, are available from AR-X Enterprises, LLC.
" It's easy to set up an AR-15 for the 6mmAR cartridge because all rifle components (except barrel and bolt) are standard .223 AR-15 parts. Minimal modifications to the rifle are necessary to make an AR-15 function in 6mmAR trim."

Smith & Wesson Model 67


Because 'Magnum' isn't always necessary!

"The Model 67 is the stainless steel version of the no-longer-produced Model 15 - rated for six shots. of .38 Special +P ammunition.
Models 10 and 64 have a heavy barrel and fixed sights while the Model 67 adds an adjustable rear sight and red ramp front sight. All three are built on the medium-sized K-Frame that has been around since 1899 under different names."

Heinie Straight-8 Tritium Night Sights

Heinie Straight Eight (2Dot) Tritium Night Sight Sets
   (The "Big Dot XS" sights [https://www.amazon.com/s?k=XS-Sight-Systems] operate on the same principle).

Review in Amazon (very polarized - mostly 5s & 1s):
"Good sights, the front sight is a little hard to pick up so I painted it with some Orange Fluorescent Enamel Paint Testors. This helped a lot, these sights are very precise so I have them on my Glock 34, I installed them with a rubber mallet and hard plastic punch. They went in really tight but I got them on. Hope this was helpful."

Straight 8 Sights vs 3 Dot Sights – Which Are Better?

Shooting range at angles

https://brycetowsley.com/tactical/all-the-angles
"The laws of gravity are fixed, the bullet is still dropping to the earth at a rate of acceleration of 32 feet per second-per second no matter what angle you are shooting from. What has changed is the angle or the line of sight relative to the bullet's path. This makes the shot impact higher than expected, both when shooting up and when shooting down.

The key to hitting the target is found in doing the math, using the proper cosine to figure the hold or dial up, or let one of the ballistic programs or apps handle it. What you don't need to worry about is the "flat line distance" to the target."
