Came across something today with a mates gun that i have never before experianced, to be fair i think there is another issue to sort on it, yet bringing it in on a reasonable zero on 55 grn factory we switched loads to another brand same 55grn weight and it lirally left the paper - yep over 8" at 100yds.
Now i realise each load has its own zero but i think the most i have ever experianced personally is around 2" shift between loads at 100yds. Does anyone find this sort of difference with a rifle they have owned?
