I would be concerned due to pressures usually over 55,000PSI with those - however - there are .458's and .375 belted DR's- but not on shotgun actions. Sorry- just thinking in print- I've perhaps go for a larger case to give those handgun ballistics but keep pressures in line- ie: .45/70 would certainly do it and then a bunch more ballistics & with under 45,000SPI. |
