I had purchased a box of Hornady's new LeveRevolutions and have loaded a few so far with various loads for testing. I myself used the Lee Factory crimp. I hope that I have put enough crimp on these. After I crimped them around the cannular, I can see the indention's around the mouth of the brass where the cannular is. Do you think for an added safety, I should maybe adjust the FCD a little more and do a bit more crimp?

I truly don't think you have to crimp a LeveRevolution bullet into a case. The dynamics of the soft tip bullet should soften all impacting during working through action and firing.
I spent most of the day yesterday cycling crimped and uncrimped rounds through my 1894 Winchester, then 2 hours at the range shooting and measuring the rounds as they were recycled through the rifle.
Here is an example of what I did in 8 different tests.
Test 1 COAL 2.542" 150 grain round nose soft points 6 uncrimped dummy rounds w/fired primers.
Rounds numbered & loaded 1-6 and and cycled through the action 10 cycles.
On the 10th cycle loads were compared. Load #4 was notably shorter measuring 2.438"
11th cycle ------------ 12th cycle ---------- 13th cycle
1. 2.500 ----------- 2.496 ------------ 2.494 -.048
2. 2.508 ----------- 2.508 ------------ 2.506 -.036
3. 2.419 ----------- 2.404 ------------ 2.383 -.159 **
4. 2.501 ----------- 2.500 ------------ 2.500 -.042
5. 2.508 ----------- 2.505 ------------ 2.502 -.040
6. 2.535 ----------- 2.535 ------------ 2.535 -.007
All bullet tips were deformed.
Test 2 COAL 2.542" 150 grin round nose soft points 6 Crimped dummy rounds w/fired primers.
Rounds numbered & loaded 1-6 and and cycled through the action 10 cycles.
On the 10th cycle loads were compared. Load #3 was notably shorter measuring 2.500".
11th cycle ------------ 12th cycle -------- 13th cycle
1. 2.529 ------------ 2.529 ----------- 2.529 -.013
2. 2.526 ------------ 2.525 ----------- 2.523 -.019
3. 2.542 ------------ 2.539 ----------- 2.538 -.004
4. 2.500 ------------ 2.498 ----------- 2.498 -.044 **
5. 2.533 ------------ 2.533 ----------- 2.532 -.010
6. 2.535 ------------ 2.534 ----------- 2.533 -.009
All bullet tips were deformed.
Test 3 was with 150 grain RP factory loads Round # 3 again was the shortest after 10 load cycles.
Test 4 was with 170 grain FED COAL 2.505 factory loads.
This test was set to fire round 6, 10 times and measuring rounds 3, 4 & 5
with rounds 1 & 2 being dummy's.
3. 2.478
4. 2.488 = loss of .017"
5. 2.478 = loss of .027"
Summation;
While non-crimped 30WCF cartridge's will function just fine as long as they are not cycled through the action too many times, all cartridges that are in certain positions in the magazine (tubular) will exhibit movement.
This test could have been done much more extensively had the weather been warmer. My fingers were getting so stiff that I was having trouble holding the pen @ 17(f). However the 100 yard turkey had a much worse day
