I had a 336 30/30 rechambered by JES reboreing
I used some 308 Brass .. as others mentioned. Didn’t eject like the 307 …. I loaded up some 130gr Speer …
And 150 gr Federal PS .. this was before the 308ME
But Imagine using the Hornady LVR powder you could work up some loads …
I also owned a 356Win and a 375 win
Id like have seen Winchester follow through with the
400 Winchester.. I do believe that one would have been the most popular.. now the Winchester has the 400 L
