Are there any factory 1-oz. loads in 12 gauge loaded here that have pressures less than 10,000 psi?
Yes, I'm well aware of RSTs...and so I'm really asking about low-pressure loads available from Rio, Remington, Federal, Winchester and any of the other larger commercial cartridge makers.
Same question asked another way:
For owners of British 12-bore guns with 2 3/4-inch chambers and 3 1/4-ton proofs, are there low-pressure loads currently manufactured in the U.S.? (As many already know, the 3 1/4-ton proof equates to 10,000 psi or a little less.)
Any guidance appreciated.
