If you have never called Hornady Manufacturing, I highly suggest you do sometime. In an era of out-sourced call centers and a general devaluing of customer service, Horandy can still be found to have class and true dedication to their customers. Upon calling Hornady you are greeted by the ambiguous corporate answering machine that implores you to listen to the following options as they may have changed. Just about the time you are certain you have landed squarely is a depressing game of telephone maze button mashing to talk to a real person, the cadence of the recorded voice changes. You are assured the following options have not changed, and further, pressing zero at any time will take you to one of Hornady's friendly staff.
Zero did indeed direct me to a very polite staff member who answered promptly and never used the dreaded "hold" button. I was amazed and shocked at how I was treated. It was as if I was a celebrity, and they had waited all day just for me to call. It was a breath of fresh air in an otherwise dingy, choking cloud of poor customer service that our consumer market place has become today.

With my new bullet selected, I set out to find some of the beautiful red and gold boxes of said GMX ammo. With a little bit of luck I found some at my local Cabela's, but was shocked by the sticker price. $42 per box of 20 made each shot just a smidgen over $2 a round, a pricey sum for 308 ammunition. This was a steep price compared to the $27 per box for the same ammunition in the SST bullet.
With my bullets purchase, rifle cleaned, and several new target stands built, I set off for the Colorado prairie to test and compare the two bullets out of my trusty custom AR10. My AR10 was built specifically for me by Colorado Mountain Sales, CMS Arms, out of Aurora, Colorado. It has an 18 inch stainless steel, free floated barrel made by Black Hole Weaponry. This specific barrel has 3 grove polygonal rifling, which is different than traditional enfield rifling. The upper and lower are built by DPMS, is their LAR10 series, and has a two-staged CMML match trigger group installed.

Day two at the range saw temperatures in the lower 90s and the winds were intermittent at 5 to 15 MPH. This made shooting difficult to say the least. After several groups at 200 yards I had to resign myself to the fact that I could make no determinations off any distance greater than 100 yards for the day. I shot several consecutive three shot groups of both ammunition and found the absolute opposite effect I had seen on day one. The GMX performed better than the SST. It appears the SST is more susceptible to wind than the GMX. One GMX group at 100 yards even saw two bullets go through the same hole. I ended the day shooting the GMX and SST at distance targets up to 400 yards. I found both bullets performed decently well despite the windy conditions.
|100 yard GMX group, yes that is two bullets in one hole.|

Closing thoughts this time are my own: Practice and test your gear regularly, do not be the hunter that relies on luck or pure chance at the moment of truth.
