The "factory" part of the shop is running during the day manufacturing bullets. But the engineering is done at night. Those guys are also shooters and hunters and decided to combine their mechanical engineering skills with their passion for hunting.
Yep, I do love their bonded core bullets. All of the bullets I've recovered were text book examples of how their advertised to work. I've not worked with the solids yet, but plan to when the time for a DG hunt arises.
I do think the A-Frames from a terminal ballistics point of view are virtually the equal of the NF bonded cores. But even though the A-Frames are shorter, they typically for me have required more powder to achieve the same velocities. I've also found the NF's easier to develop a load for, perhaps just one person's experience however.
The only drawback I find to using the NF bullets is that they're true diameter for the caliber. If you measure say a .308 NF bullet, it is truly .308, whereas another bullet may be .306-.307. Why is this a drawback? It makes the NF bullets less tolerant to uneven neck thickness. When first working with their bullets in my .300WM and my son's .308 Win, I'd find that roughly every 4th shot would be a flyer. Discussed this with Franz in Dallas and he figured it was my brass. The solution was to either turn my necks or buy better brass. I chose the latter and use either Lapua or Norma brass in the medium calibers. Once I made that change, no more flyers.
By the way this problem only seems to be in the smaller calibers. In my .375H&H I've not seen this problem and use Remington brass. So hopefully this won't be an issue in your Lott.
