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.

I bet CFE223 would work perfectly in the 375 Whelen
I got banned on another web site for a debate that happened on this site. That's a first

I heard Accurate 4064 makes a good substitute for IMR-4320, though with the amount of 4320 I have, i may not get around to load analysis to test this claim. The Accurate powders tend to burn slower than the others of the same number.

I’ll look for that article. I’m going through my old Rifle and Handloader magazines.
I prefer classic.

Bugger,
Have you looked at the Hawk Cartridges Manual for .375 Hawk (a .375 Whelen Imp variation) load data?

Ed Is it on-line? I know people have had good luck with Hawk Bullets. Unfortunately, I’m not one of them. My understanding is they have an annealed copper jacket and that their load data may be light compared to gilding metal jacketed bullets. I’ve only used 35 caliber Hawk bullets. I think the best group was about 4” at 100 meters.

The book contains load data for other than Hawk bullets and is a starting place for me and my .375-06 RCBS (.375 Whelen with a 30% shoulder and a full caliber neck) The BL-C(2) loads for the 235gr Speer SP were very accurate in mine.
