Are they both Sear block? Can both actions be field stripped without tools? Are the Rugers True CRF?

Ruger locks the trigger(safety blocks trigger movement) . Wing safety in the full rear position fits in a notch on the cocking piece effectively locking that. Winchester locks the firing pin only. Winchester is easily field strippable..you will need a small finish nail to strip the Ruger down.

How about the dissasembly of the bolt and firing pin, and the true CRF function. I had heard that they have a claw extractor that "looks" like CRF but is not actually a real CRF action.

Thanks for the safety update

Same tool that will disassemble a Remington bolt will work on a ruger bolt. Can't help you on the Winchester at all. The Ruger is a CRF you can drop a round in the chamber and then close the bolt over it. BTW I enjoy reading your posts concerning the 30-06 and the 165 grain interbond. Maybe someone else can chime in on disassembling the bolt shroud/firing pin on a Winchester.

On my PF Mod.70, it's very easy. Cock the bolt in the rifle, put wing safety on half (middle position, remove the bolt from the rifle,
push in the little locking plunger on the front left of the bolt shroud then unscrew the whole thing.
With the fireing pin out the bolt can now be reinserted into the rifle to test feeding of live rounds etc.
JL.

JJ: The old Rugers with the tang safety have the claw extractor, but they are push feed. The new ones are CRF. To disassemble the Ruger, insert a small finish nail or punch in a hole that is drilled in the cocking piece. Then the shroud and firing pin will unscrew.

Thanks guys
