If it reached any popularity at all, it should be in PO Ackley's Volume 1 handbook on wildcats. Its not in the Barnes Book.
Frankly, anything smaller than .348 on the 348 WCF case is not particularly reliable or efficient, unless you inherited a basement full of 338 FP bullets.
That would work well if they were Hawks, Woodleighs and such. A re-barrel effort might be worth it. The 348 WCF case is made for lever actions and larger bullets.
