Sight your rifle in for a clean barrel.
This has worked very well for me.
But also know what the difference is in POI on a fowled.
That is a big issuewhen using 777 and the 250 grain SST/ Shockwave in my Encore.The difference between a clean and dirty bore is4-6" or even more. There is nochange toPOI wheni use JSG and Pinnacle.
