The 215 did not stabilize totally from the 1/24 but again remember that is a 40 cal bullet.
I certainly concur that a faster twist 50 has its advantageous. As Scott indicated the Knight 52 with the 1/26 twist certainly showed it could shoot the long .458 bullets with great accuracy. And I believe Grouse has shown how well it works with the short stubby .458x220 Bloodline.
I think we are at the max length with several monolythic bullets from the 1/28. The 1/24 was/has been proven a long time ago the better twist for the longer bullets.
Because of State regulations and the way they have to be written the 50 cal. will always be the more desirable caliber for the most. It offers a wide range of flexibilites.
This not to say a fast twist 45 would not be a good thing - it would not be as versitile as a 50 but it certainly would satisfy and meet the needs of a good size group of people.
