Grendel Load Test

 Took the Grendel to the range late this morning. What I consider high temperature and high humidity caused water to condense on the rifle, that is stored in air conditioning. The scope lenses also fogged, so I had to wait to start shooting.

I had 3 loads each with 2 different powders. The groups were inconsistent at best. Seems the Grendel is a bit finnicky about powder charge weights. A 0.3 grain difference can be significant. To make things worse, after getting home, I noticed that the linear compensator had loosened. Now I'll need to redo the experiment.

Oh well, a bad day at the range is better than a good day at work.

6.5 Grendel

 Made it to the range yesterday with the AR 6.5 Grendel.  I had 8 experimental hand loads using 2 different powders all with the same bullet (120 Gr Sierra). Two of the loads were promising with 3 shot groups of 1" & 1 1/8". I'll be loading more of of those and trying a different powder as well. At some point I'll experiment with different positions of the linear compensator mounted on the barrel. The weight will modify the harmonics of the barrel, frequently resulting in tighter groups.

Trip West

A few decades ago the Boss and I took our first trip west to the Black Hills of South Dakota. We liked it there, and with some pressure from me, we went back there recently. This time I was pulling a fifth wheel camping trailer. We drove through Indiana going and coming on the worse interstate highways I've ever been on. I70, I65 and I74 are all in terrible shape. At least I70 is being reconstructed. A couple of years ago I broke a band on my truck tire driving on I70.

While away a local company cleared our leaching field. He claims all is now working as required, and the septic tank should not overflow. Maybe in the spring, with all the rain we get, I'll know if that is true.
