How big of a difference have you guys found between 7/8oz loadings and 1oz loadings on the pattern boards? I used what I have available to pattern a new to me o/u. It's a Tristar. The loads I have on hand 2s, 3s, and 4s are mostly 7/8oz loads in various brands (fio,win,kent), with the exception of a Hevi hammer load in 3s and BC loads(15/16) in 2s. At 30 and 40 yards by rangefinder I got decent patterns with M/IM. When I had some 1oz loads in the past, another firearm, IC was the choke with decent patterns out to 35-40. ( best was Rio 1 oz) I know every firearm is different and responds to loads differently. Just curious if anyone else has noticed any differences. The HH load was the least impressive on the pattern board, Win and BC 2s, Win 4s and Fio 3s were very respectable and Kent 3s was by far the most impressive in 7/8oz. This is with the factory chokes. I could work with maybe LM/IM but I'm curious when I use up this batch of ammo (will take a couple seasons) and go back to 1oz if I'll have to order a different set of chokes.
