The only way that Hornady is going to change it's product is if people stop buying it. It's a simple matter of economics. As long as people are foolish enough to pay good money for a substandard product they will continue to manufacture it. People need to speak with their pocketbooks and stop paying good money for this garbage. Time and again people have told horror stories about these bullets failures; yet some people continue to support the company and it's product.
I will not purchase anything with the Hornady label. The brass they produce is substandard. Open any box and you'll find cases that are dented and deformed. They continue to produce it because people continue to buy it. Its sad that so many people will accept second class merchandise. It's cheaper than other brands so they think they are getting a deal. I purchase quality, even if it does come at a higher price.
This isn't about the DGX bullets with which I have no experience.
I usually reload for whatever I use for hunting. However, I was curious to see what the Superformance ammunition Hornady manufactures was all about. I read from some that the primer pockets were loose after one firing, that the primers were cratered, that there was a black ring around the primer after firing, that the cases came out deformed and covered with powder residue, that the loads were too hot...And on and on.
I satisfied my curiosity by buying a few boxes of 300 Win Mag Hornady Superformance both in 180 grains SST and 165 grains GMX.
The SST is supposed to fly at 3130 fps from the muzzle. I obtained out of three shots the following; 3128 (fouling shot), 3133, 3134 and what I consider exceptional accuracy. No dented cases, no flattened primers, nothing unpleasant.
The 165 grains GMX is supposed to fly at 3260 fps. The speeds I obtained were 3259 and 3262. The accuracy was better than my best reloads. One hole. The cases were in superb shape and the primers did not show any sign of a load that could have been too hot. None whatsoever. I know what to look for. I also measured the cases for expansion at the base above the belt and in different sections of the case. Expansion was within 3/1000th to 3.5/1000th at its widest above the belt. In other words, perfect. This isn't strictly a function of the chamber but a result of good ammunition.
For both loads, the recoil was quite inferior than lesser quality ammunition in the same caliber, at lower speeds. Feeding and extraction were both very smooth, uneventful and flawless.
I disagree with your claim that the brass Hornady produces is "substandard". That the cases they produce are dented and deformed. Of the six boxes I shot, all were in superb condition. Their primer pockets, after firing, are tight. These cases are in pristine condition. Well above average.
Over the decades I've been shooting, I have on occasion tried manufacturers' ammunition and without exception, this ammunition fell short of their claims both in speed and accuracy. Hornady has been the exact opposite. Your criticism is too broad and is very contrary to my personal experience. I'm not interested to write purely to contradict someone. But I am qualified after many decades of shooting, competing and producing my own wildcat as well as shooting several in a variety of calibers big and small, to give a personal educated view which happens not to coincide with yours.
Hornady's claims that their Superformance ammunition is faster than conventional ammunition but recoils less has been my personal experience. I bought all the boxes I shot. No one is paying me to shoot their ammunition. I will definitely hunt with this ammunition, it is outstanding, very fast, reliable, repeatable, accurate at short and extended range, also faster than my best 300 Win Mag reloads.
