Are there any forum members out there in interneck land who would be able to discuss real world experiences and differences they noticed when loading the same type and weight bullet (180 grain -220 grain range) in both 30-06 and 35 Whelen.

I understand the differences in BC and SD.
I understand that the 35 Whelen has slightly more powder capacity if you pack it full because of the wider neck.

Does any of this translate into noticeable real world differences?

Thanks in advance for your replies.
