Push Round Control Feed Question

Hello All,

Can someone explain to me the effectiveness of the M70 push round control feed? Is it truly a control feed or is it a compromise?

Respectfully,
Harry

Harry, I've lost track of M-70 rifles since the new WSM and WSSM models come out.....I don't keep track of them and if it's those models you're talking about I apologize.....I have no clue nor do I want one.

However as for all the traditional rifles post 64 and pre 64 they made basically two models.

The pre 64 rifles and the post 64 classics are known as CRF meaning controlled round feeding rifles. These rifles use a large claw extractor that catches the round being fed from the magazine between the bolt face and the claw such that the round is actually held in place before it is moved to the chambering area prior to being forced from the magazine. It's "controlled" before and during the entire process of chambering a new round.

The other models made after 1964 are known as push feed actions. They push a new round from the magazine and push it to the chamber and then finally catch the round between the extractor and the bolt face as one closes the bolt handle. This is as the M-700 Rem, the weatherny rifles, the sako rifles the Savage rifles.....etc.

There may be such a thing as a "push round control feed with the WSMs or WSSMs but another poster can elaborate on that.

Hi Vapodog,

Thanks for the response. I am pretty clear on the differences between crf and push feed. I am just curious about the mixing of the two in some of the new models.

Best wishes,
Harry

As I understand it the push feed crf exctractor snaps over the rim when the round is seated, not when it is picked up..

The new "Control Round Push Feed" M70 is, IMHO a very clever mix of the two. The cartridge slips under the extractor just like a CRF action, but there is no non-rotating-mauser-type extractor. It doesn't look as "cool" as the CRF action, and the extractor doesn't take as large a "bite" on the case rim, but it certainly works well on my M70 Wal-Mart Special. And it's probably cheaper to manufacture also. I believe that all M70's are now CRF ("Classics") or CRPF (no more push feeds).

Harry,

The CRPF model 70’s are a fairly clever solution that combines some of the best features of both types.

What it basically is, is a post 64 model 70 recessed bolt face with the lower half of the recess gone so the cartridge can slide up and under the extractor just like with the Classic 70’s.

What it can also do that is difficult, if not impossible with a control round feeding system is allow manual loading of one round at a time like you can do with a push feed system. It also goes back to the fixed ejector style like the classic and does away with the spring loaded plunger type.

I would assume that some of the safety of a totally recessed bolt face is lost by doing this...but I have not heard of any accidents caused by the system...and it would be no less safe than the classic style bolt face that isn’t recessed at all.

Is it a compromise? Yeah, of course it is...but that doesn’t mean it isn't good or that it doesn’t work well.

I don’t own any model 70’s (or any Winchesters at all for that matter) but I think they are extremely well made nice looking and handling rifles that will shoot right along with just about anything else out there.

Thanks for the insights. This is something that I have been wondering about for a while. Harry C.
