I have an old double with replacement Charles Hellis steel barrels. The barrels have been honed and the BWT on one of the barrels is .023 at 8 from the muzzle. At 15 from the muzzle the BWT goes up to over .025, and in front of the forend where I grip the barrels with my left hand the BWT is over .030. RST makes a 1 1/16th oz. hunting load with #5 and #6 shot. RST says it generates 6200 to 6500 PSI. Would you have any hestitation shooting these 1 1/16th oz. RST hunting loads in the described barrels? 6500 PSI still seems light in comparison with many target loads.
