Today I sighted in my 30-06 using 180gr Gamekings at 100yds (54gr IMR 4350, Win Cases & primers). After sighting in and getting 3/4" groups I switched to begin pressure testing for some RL-19 powder. These loads are 180gr Horandy Interlock (NOT SST) with 53gr in Fed cases and Win primers. When referring to Sierra's reloading book 54gr gives about 2700fps, and Horandy shows 53gr gives 2400fps. (Bear in mind the Gamekings have a higher BC than the Interlocks. I don't have a chrono to check velocities to check is.)
My Question is after zeroing with the Gamekings and switching to the Interlock's my POI went up 3" with a 3/4" group and there was signs of pressure . Did my velocity increase with the Interlocks over that of the Gamekings?
