Question about SD on Big-Bores

[rustyinbend]

Quick discussion question ...

All other things being equal, should I expect SD's to gracefully climb as the size of my bore increases? Context is that the smaller my caliber, the lower the best Standard Deviation I'm getting in my tests ... with my best 6.5-CM SD around 5.5, best 300-WM SD around 8.0, and my best 338-LM SD around 14.6.

Asked differently ... are you guys getting single-digit SD's in big bores that are equivalent to SD's in smaller calibers?

Trying to decide how much more load development work I want to put into my 338-LM.

I get the same with my 6 BRA vs. 300 PRC - 4-5ish in my 6 and 6-7ish in my 300. What I don't have is same-brass comparison (yet).
