The ONLY scope bite I ever got was behind one of them.
.50 BMG in semi and bolt, .300 WinMag, .338, 7mm Mag, .404 Jeffries, and a couple of "Nitros" with scopes...
Not one single scope bite till I shot a pals AR with a LimbSaver and did not know how much they compress.
Now, that's either a ringing endorsement or not depending upon your point of view but I despise the degree to which they compress.
Reading later posts - it should be noted that the one which I used and was garbage was in fact the slip-on style.
