RC,
After looking over the 460 G&A specs and drawings I’m having a hard time understanding how rechambering a standard 458 Win Mag barrel will leave part of the original throat. Please explain so I might better understand. 458 Win Mag case is 2.5” COAL is 3.34” both much shorter than 460 G&A specs.
As a matter of fact, it seems to make sense to start with a 458 Lott chambered barrel to rechamber to 460 G&A. Both cases are 2.8” long and COAL is 3.6”. What do you see as a problem with that plan?
BTW, I’m planning on a 23” barrel, probably a Douglas with a target weight of +/- 4 lbs. Target rifle weight is 10-10 1/2 lbs.
The 458 Win mag has a much longer throat than does the 458 Lott
