Have started load development with the A-Frames in a few rifles, but have not finalized any loads as yet due to limited time at the range. Looking forward to my own field experiences with them!
Have always read/seen good reports on their on-game performance from magazine articles and hunting videos, and know that they have earned a great reputation on plains game and dangerous game in Africa, and on other big game species around the world, including North America.
They are pricier than other brands, but you get what you pay for. At the end of the day, the bullet is the least expensive component of any hunt, and it does the most important job, after the hunter places it properly!
