Probably ought to check your Breech plug, and slug your bore. I have 3 S91’s my two .504‘s come in at .505 and .507. My .451 seems right on. I changed the breech plug in my .451 and went from 4” to 1” at 100 yards.I tried the felt wads first, they tightened the group up to 2" @50yds. The modified sabots took the group down to 0.7". Yes it's a little bit of a pain, but totally worth the time.
