Berger Tactical bullets have a heavier jacket than other Bergers and the SMK, I was able to apply a lot of crimp using LFC dies without distorting the bullets.
I wanted to see how much crimp would effect the pressures and velocities of the load, so I applied as much crimp as I could without the common signs that it was excessive.
If I felt the need to crimp this load or someone wanted it crimped I would use about 1/2 the pressure I used in crimping this test load.
Final pic 1-5 are non crimped 6-10 are crimped.

A couple things interesting about the 5 and 5 test.
Judging just on velocity the 10 rounds of 5 each showed the best consistency in all arias, lowest SD, MAD, and ES of the 10 shot strings.
However on the strain gage it shows two curves that don't fit the others, they show sign of slightly delayed ignition and one shows lower pressure.
The end result of the two that don't fit is about .03 and .07 respectively of a millisecond more time in the barrel and 4 - 22 fps off from the averaged velocity.
It gives an interesting perspective on what a strain gage can tell you that a chrono can't.
