Factory shell pressures?

[Joe D.]

This is not a reloading question. I am wondering if anyone has tested pressure results from either of these factory 12 gauge loads.
The first in question is Westley Richards Supreme game loads 2 1/2" 30 grams 1 1/16 oz. nickel plated #7. I believe they are Lylevale Express manufacture which was one that Michael McIntosh spoke well of. I shot these years ago in a Husqvarna 310 AS and they were amazing on pheasants. I have a lot left and would like to use them up in some Parkers but need a pressure check first.
Next is B&P 2 3/4" 33 gram 1 1/6 oz. #6 (spreader- dispersante loads). I have not shot any of these and do not know if they are suitable for vintage guns.
Any information on either of these will be appreciated. I have 3 flats just taking up space. Thank You
