Thank You Daryl !
I didn`t ecpect to hurt anybody when I remarked that a belt is useless. I referred to the .450 Dakota and of course not the .458 Watts/Lott. I just believe the belt wouldn`t improve the cartridge, the sexy shoulder surely ensures proper headspace, as it does in the .416 Rigby. And just maybe the great old .375 H&H belted rimless would be just as great without a belt.
Sorry again for not choosing the right words.
