My own experience is quite limited with Hornady, however, I will add what little I have if it helps at all. I own two 6.5 Creedmoor rifles (a Mauser M18 and Tikka T3x). Both shoot the Hornady Interlock 129 grain factory cartridges very accurately and for white tails they do exactly what I need them to. I paid under $17 per box with free shipping, and so far I just don't see any reason to change for this purpose.
Hornady offers several fairly unique technological attributes which I appreciate, at least on the surface:
1. The partnership with Ruger is attractive, though if you don’t have confidence in the bullets and don’t handload, this doesn’t work.
2. The Leverevolution theoretically make the 30-30 a much more useful cartridge and I had thought to try them in my grandfather’s Winchester ’94, but if they fail as badly as Skinnersblade demonstrates above, then you won’t get the extra range or better trajectory, so what is the point? I had not heard this was a problem, but will be researching further.
3. The Superperformance line of bullets looks attractive and paired with their 180 grain Interbond at the advertised speed of 2,820 fps in my 30-06, I had hoped that this would be a great elk or moose combo. I think this combination has since been discontinued and I have read a few reviews saying that the Interbond is a much softer bullet than an Accubond or Oryx, however. Am curious if any forum members have experience as I still have a box of these laying around.
Finally, my best friend and sometimes hunting partner is one of those odd guys who actually prefers to shoot his muzzle loader over a modern rifle any chance he gets. He has used the Hornady SST .45cal sabot bullet in his .50 cal muzzleloader on several deer due to it giving him the very best accuracy among many different bullets he has tried. He finally gave up on them this past season and made a switch, however, due to minimal blood trails and recovering bullets that have failed to expand sufficiently lately.
The poor customer service and allowing ammo with known deficiencies to continue to circulate and be sold is very upsetting and I hate the idea of supporting a company that would allow this to happen. They have seemingly done a good job on producing accurate bullets (from my experience), innovating and providing a wide range of calibers and products, however, there are just so many stories out there with them having issues with their bonding technique and creating bullets with the correct hardness that it is hard to ignore.
