Need an ARCA clamp

[nksmfamjp]

I'm shooting a 300 Sherman off a sturdy tripod. The clamp slips in recoil....a lot. Shooting with shoulder on the stock. I'm having trouble with the rifle ARCA rail slipping in the arca clamp.

any suggestions on a better clamp? What is working for you?

An area 419 clamp combined with their rail will ensure it doesn't slip at all. The rails are serrated and the clamp engages the serrations, and mechanically locks it in place.
