Although not a comment on the Accutrigger, at one time I owned a Savage M110 variant (M116 I believe) in 458 Win Mag. Savage billed this gun as “controlled feed,” but the extractor was not a claw. In practice I found that if the action was operated briskly, the bullet would rise too high and snag on the top of the breech opening. If operated slower it fed perfectly. The gun went back to Savage twice, and the condition was never corrected. I would be worried about follow-up shots under stress. However, another rifle (or another DG caliber) might work wonderfully.
