Winchester's mod 70 was a full length 375 H&H action anyway, so that case could have been used, with no problem. The reason the 500 gr bullet was used was because though they knew the speed wouldn't be there in the 22" barrels of their rifles,

The .458 Win Mag was introduced in 1956 in their CRF Model 70, which later became known as the "pre 64".
These did not have 22" barrels. They were 25".
AFAIK 22" tubes didn't appear on the Mod 70 .458's until '64 or later, on the push feed Mod 70 action.

On the side of Winchester, they didn't experience the failures that happened in the field. That is because they were using 30" test barrels and shooting fresh ammo at their plant.

I'm curious to know where this information came from, ie the 30" length being used for testing.
Thanks
