I've done a LOT of patterning with both of these in my Winchester & Mossberg Non-Back-bored guns and as mentioned already they all have patterned best with either the standard I/C or MOD chokes. At 50 yds with the 4 Buck load and MOD choke I consistently get 6 pellets in 8" @ 50yds and all 24 inside 30". The I/C gets 5 in the 8" and all 24 pellets inside 36". The BB loads also had a very even/complete coverage of the 36" paper with the MOD choke at 50yds. The I/C choke had a more spaced out pattern but all were on 48" Plywood.
I run the BB load with I/C as a backup to my Rifle on my Lap on field edges/treelines for short range reaction shots out to 50y and I run the 4 Buck with MOD choke inside woods where I have time to aim at them and possibility of shooting through timber out to 75yds..
FWIW in open timber I use a 18.5" Pump Carbine .308/Low Mag Thermal with 110 Vmaxes @3350fps.. Fast follow up shots like SG, but real world range of 150yds. Kind of the best of both worlds in the Timber.. Gun weighs 7.5# . I have been trying to buy one in .243/25-06 but prices have soared on them...so I may turn to a Rem 7400(semi auto)..
I've done the AR thing and I just don't like the Pistol Grip when sitting and trying to shoot offhand.
