I had a bit of an opposite experience with my 300 Wby. When I was developing loads for it, the faster it went the tighter the groups got. I'm not sure this is as much a "velocity" thing as it is the % of the case being filled. Starting loads were nearly 2" and when I stopped working they were down to 3/4". I still had room to go, but ran out of time and didn't really go any farther on that experiment.
This nice thing with wild cat would be getting at or above 300 Win velocity without pushing the pressure limits at all. That is never a bad thing with wild cats since the brass can last longer! Less fire forming or expensive custom case orders.
Ya, the Weatherby's seem to be on the limit of high velocity and good accuracy. What I'm talking about are the 'Big' cased .300s. I think to have over 80 grains of powder with good accuracy takes a fairly heavy barrel to balance out the harmonic vibrations that, that much powder burn creates. I just think there is a limit there someplace. And I think the WM & Weatherby are about it, in terms of velocity and accuracy. Cheers |
