In hearing that the Grand slam may be tough in the 6mm, an my velocity are min charges and correspond to 2400fps from the Muzzle I believe it was-
This would be limiting the expansion to about 250m on the farthest end..
Without jacking up the charges to be closer to 2600fps , I'm wondering if the BTSP interlock 100gr might be better suited for that lower velocity but decent expansion a bit more reliably -
Has anyone any experience?
