Some guns just shoot them better than others. My A5 with the Hastings barrel is excellent. My Mossberg's with fully rifled barrels are pretty good too, as are the one with the Carlson's Rifled Choke Tube. But none of the Mossberg's are as good as the Hastings barrel on the A5.
You've seen the group from the A5 with SRU Sabots and turned Brass Inserts, the first three shots were the Clover Leaf in the center and then I added to two others after looking thru the spotting scope. After looking in the barrel I found some plastic fouling and figured that the accuracy was deteriorating due to that.. So subsequent loads with those slugs all had Mica on the sabots which cut down on the fouling dramatically. I don't see any need to run these slugs over 1300 fps. My load which came with the SRU Sabots I bought back when, was 23 gr of Unique, and I used new RIO Primed Hulls.
