Mac, I already have agreed with that several posts back!

Here it is again.

"You are correct that the 458 has too small a capacity for easy and efficient loading of the 500gn bullet to the original claimed velocity.
You are correct that the 458 Lott has the powder capacity to easily and efficiently get that original claimed velocity and more.
You are correct that the Lott is a more efficient cartridge than the 458 Win.
You are correct in that if Winchester had made their 458 on a longer case it would have achieved the claimed velocity and may have avoided the problems encountered with the standard length case."

In reply to:

4seventy , we are on the same page, you and I, but one of us is reading it backwards!

Mac, I think you're right!

One of us seems to be constantly going backwards to the 458's dim dark past!

I'm interested to hear of your experience with 458 WM failures which involve those hangfires, squib loads etc.
