Reviewing it could be the more the 458 just looked longer,
as several guessed 458 Lott.
That rifle has a long throat.
As you can see I began loading the 405 gr bullet to the longer 2nd crimp position, thinking it would help both accuracy and case volume.
Turns out the COAL for those loads and that rifle
wasn't an important factor in accuracy like it could be in another situation.
Which was good for me - I could concentrate on getting those 2 reloads to shoot to the same POI at 50 yds.
PS: Glad you enjoyed it. I had fun, too, being on the other side.
