  • Day out Shooting

    I went out yesterday and did some long-range shooting with some friends. We were testing a new Know Your Limits rack my buddy had built. In addition to being an engineer specializing in prototyping advanced alloy devices for the medical industry, a gunsmith trained in two different schools...he also is a very good welder, fabricator, and problem-solver.

    Here is his new plate rack system for KYL:



    We moved back to 500yds, and worked over the plates. They had their .260 Remington's, one an Armalite AR10, the other a sleek bolt gun, and I took 2 Grendel's-my 16" and a 20" rifle I am accuracy-testing.

    I let the other guy shoot my 16" Grendel, and he cleaned the rack down to the tiny target using my hand load of 31.2gr of CFE under the 123gr A-MAX.

    Factory 123gr SST Hornady clocked 2602fps from the new 20" Lilja barreled upper, and was holding MOA with wind gusts even at 100yds. Vertical was less than .5" on one of the groups I shot with it.

    I also made a 1st-round hit with my 16" Grendel from a kneeling position on a 26.5" gong plate at 500yds, first try of the day, and encouraged my friends to work on their kneeling and seated positions, which we did into the evening.

    Made a new convert to the Grendel as well.

    That is a sweet, portable plate rack. It looks like it is pretty solid too. The small plate looks to be about a 4 to 6 inch plate, nice shooting.

        Nice report. Any chance of the CFE temp stability comparison in the near future now that you are out shooting again post-move?

          The .260 Remingtons were 26" and 22" barrels, versus my 16" Grendel. The .260's hit the plates a lot harder, but I could have told you that years ago. Hit probability wise, the guy who tried my Grendel cleaned the KYL rack with it as I mentioned, so the biggest thing really is wind. The 16" Grendel trajectory is more like a .308, but with less wind drift and almost no recoil, which is why I got totally out of .308 Winchester.


          I intended to do cold weather testing with my CFE ladders, but no dice. I'll test it up to whatever hot weather we get. If it ends up being anything like last year, we'll have temps over 100 F for a long time.

              This! I am seriously considering getting completely out of the large frame .308 AR game because of this caliber. I'll keep my .260 just because it is a custom build but it doesn't see a lot of range time anymore really.

                With 31.2gr of CFE under the 123gr A-MAX, COL = 2.275", I'm at 2500fps. 31.1gr gives me 2489, 31.4 = 2520, 31.7 = 2532, 32.0 = 2553

                I mass produced the 31.2gr load last year before I explored beyond it, but 2500fps from a 16" with a .510 BC makes me pretty happy.

                The 20" Lilja gave me 2602fps with factory 123gr SST. I had no issues with the primers on any of these loads-everything was nicely dimpled, although primer signs are unreliable for determining pressure. I mention that because some have reported pierced primers in other guns.
