I believe there is some merit to his argument, it was his delivery that killed any merit.
Look at the 6.5 Creedmoor, Hammer bullets and similar products, it's not the product that killed the desire to utilize them, it's the over the top fanbois. I refused to buy into the Creedmoor for along time, then I built one on the AR platform. Refused to buy a bolt gun, now I have 3 of them, they all shoot small groups. I have a sample pack of Hammer bullets to try in my 280 Ackley, I suspect that I will be more than satisfied with their performance.
No denying the 6.5 Creedmoor and it's abilities, it's inherently accurate, carries significant energy down range and is very soft shooting. What's not to love, it's a well thought out cartridge that delivers.
The same with Hammer bullets, very accurate, increased velocity extending range and they kill efficiently. Again, what's not to love.
It's the messenger, much like both of his posts, kinda ironic isn't it?
One thing I love about certain forums is the free exchange of ideas and information in a respectful manner. One thing I hate about 24hr and similar forums is the BS and hateful drama that you have to wade thru to find a nugget of information.
