In short, yes. Different .458 Winchester Magnum rifles have different throat lengths which make it more or less difficult to achieve a higher velocity. Longer throats make it difficult to achieve higher velocities. Shorter throats make it easier.
The Winchester Model 70 has a long throat which makes it difficult to achieve above 2090 FPS with most .458 Winchester Magnum ammunition. The 22" barrels of the post '64 Model 70 rifles only made matters worse.
The best rifles ever made for the .458 Winchester Magnum, were:
A) The Mannlicher Schoenauer (only 77 made in this caliber)
B) The BSA Majestic (only 257 made in this caliber)
They had very short throats and permitted velocities above 2100 FPS to be easily achieved. In the case of the BSA Majestic, this was impressively accomplished with barrels that were only 20" long (minus those beastly muzzle brakes).
Now, the advantage of the long throat in the Winchester Model 70... is that this makes it better for conversions to .458 Lott.
