Nope, don't have one, but always wanted one.

The shoulder problem is a myth on the 375. Less so on the 40.


As one with considerable experience with a 40 Whelen (properly known as the 400 Whelen) I can assure the shoulder problem is a myth in the 400 Whelen also. I have used mine for 10 years, done extensive load development and shot many hundreds of rounds(1200+) and have never had any of the mythical headspace issues. The late Michael Petrov was friend and the one who inspired me to build mine. Michael wrote a couple of great articles on the 400 and probably had as many rounds through his as I do through mine with the same findings.

2150 with a 400 grain bullet is a reality.
