Magnum loads

I agree with mr Brooks. No point ruining a nice gun. And I would be surprised if a 9 percent increase in barrel translates in to only a 9 percent decrease in preasure. Changes in bore size are rairly proportional. I believe after the wad leaves the chamber mate it no longer makes a seal in the 10ga bore and the preasure drops drasticly. If Iam wrong I am sure bsomeone will correct me.

I use Gage Mates often. Modern 12 gauge plastic wad seal good in a 10 gauge barrel.
