375 Whelen AI - 05/21/22
One of the cartridges I’ve been interested in is the 375 Whelen AI. I built one on an between the wars 98 action; the rifle has a Lyman steel aperture rear sight and a post front. The following photo is from an article July-August 91 Handloader 152. Note the velocities are from a rifle with a 20” barrel. The author seemed to like 270 grain Hornady bullets, RN & SP. Unfortunately his best loads seem to be IMR4320. Which is my favorite powder in several rifles. I only have 3 or 4 lb left.
