I have 4 3.5-15 LHTs.l, one 4-21 or whatever the exact numbers are.
My first LHT sits on an 8# 340 Weatherby. I have 400 rounds through it with this scope. Very heavy recoil. Always dead on when I check zero.
Another is on a 308 that is my daily hunter here in Kodiak when I don't need the 340. It has been on rough mountain goat hunts, boat rides, washboard roads, fallen over a dozen times. Every time I check zero it is dead on.
The illumination feature could be executed better.
I have only one Credo. It's a solid scope. Only a 1-4 so I can't really compare it but I do like the illumination. The reticle in the LHT is spot on.
