... Some 400 yds off, .... I found another 300 grain a-frame from the caribou taken by the long shot. The bullet had traveled through the entire caribou resting against the hide near the groin. It too expanded wonderfully, this one to 61 caliber retaining 289 grains. I have learned something about these swift a-frames. Though many a marginal internet “gun writer” have opined that these stoutly constructed a-frame bullets may not expand on smaller game or below 1800 fps, nothing could be further from the truth. I’ve never found a bullet that has exhibited such reliable, controlled expansion, all the way down to 1500-1600 fps...
Gunwriters,,, well you are talking about some that will say one thing today then the complete opposite when its suites them. How some ever got a job writing and advising the broad [and somewhat gullible] hunting fraternity public I don't know.
