257 Roberts VS 25-06 VS .243Win

I'm not sure the .243 is all that much easier on pelts. Atleast mine isn't. Maybe the 55gr BTs would be pelt friendly IF they didn't exit. Or FMJs (never seen them in 6mm though).

You can get 6mm solids.

Its not always about capacity. The velocities obtained by the wssm surpasses the 6mm. Even with its chrome lining a 1000 rounds down the bore will greatly diminish its accuracy.
For starters I consulted my reloading manuals for this information.

I just rechecked 3 of my manuals and the Nosler shows the 243wssm a little faster with the light bullets and the 6mm a little faster with the heavier bullets, the barnes has the same trend but they max out at 85grs, the Hornady manual shows the 243wssm faster for all weights but it was tested with a 26in barrel while the 6mm was tested with a 22in barrel, so allowing 25 - 40fps per inch of barrel would put them in the same ballpark as well.

None of these manuals refer to the 243wssm as a barrel burner?

Brass availability years down the road would be my concern with the WSSM family.

I believe the manuals involved were my buddies Hornady,Barnes,Redding books.I know one of those books made mention. Why do you think they never took off? Why have the 223wssm been discontinued?
A: the smaller you get the more pronounced the effects are. 243 is as small as it goes because 1000 is the smallest acceptable number.
