A few weeks back I scored an Antique Williams and Powell 22 bore double. I got some good info from folks on here as it is my first double barrel so thank you if you helped out.
Took it out into the back today for the first time to see what sort of patterns I got. Rear trigger / left barrel is a tighter pattern and the right (front trigger) is spread wider. I did find out that using the front trigger first led to a ba-boom which sounded like a slam fire in a semi auto as the recoil or my trigger pull ALSO pulled the rear trigger. This got me thinking.. I assume that rear trigger is for tighter pattern as you’d use that first, with the thought that if needed the front was still available for a closer shot. Is there any standard for trigger/ barrel and pattern in these things??
