Is the thread of the model 70 Ranger 270 win. the same as used on winchester CRF? Have 300WBY bbl from CRF and would like to use on a Ranger 270. Other than the bolt face machineing and feed rail work. Is the thread the same on both actions?

Yup, threads are both 1" x 16 tpi.It should work just by facing off the cone breech and the extractor slot.Headspace and you're in business.I've never done it but it seems to me that the push feed Model 70 may be one of the easiest bolts to "open up". Remove the extractor,bore it out and install new extractor for .532" magnum case.You'll need a longer mag box too.

Keep in mind that most CRF factory barrels have a thread relief groove next to the shoulder,no threads for about 1/8 inch. So, if you machine the barrel end off to get rid of the extractor groove, and machine the shoulder to get enough shank length, you are left with a short length of threads. Not a good idea.

And, you need a longer magazine box and follower, shorter bolt stop, and for reliable ejection you will need to machine the rear bridge.

The safe and cost effective thing to do is to trade off the Ranger for a CRF M70. You can still get into trouble with trying to install a take off barrel. If you are lucky, the take off barrel will not screw in too far and all that is needed is a slight facing of the barrel shoulder and cone and opening up of the extractor groove. If it goes in too far, gotta take a thread off and remachine everything. Remember the M70 CRF Classic suffers from minimum threads in the receiver due to the bolt lug broaching, and taking off a turn on the barrel threads just weakens things more.

For all the above reasons I do not like to fool with take off barrels.

i got to agree with john. i hate doing take off barrels. it is usually more work to install it properly than a comparable blank and the customer still ends up with a used barrel.if the barrel will allow, i cut off the complete threaded end and start new, but not to many allow that.

Well said John. Took the words right out of my mouth. Nothing more to elaborate on here.

Hey guys, I took to heart what you said about the short BBL thread and it is a shitty job the factory did on the releif groove against the shoulder. That's a shame because it is a takeoff from a new gun. Back in the barrel and wait til a crf shows up. Thanks for pointing it out.

Speaking of which, Is the barrel face, and shank, the same on Winchester's FWT and the standard M70 XTR? In this instance, both are push-feeds. Thanks>>>>>>>>>>Bug.
