Home Forums Hunting & Shooting Custom Rifles & Wildcats Defiance Actions bolt face

I was on their website looking and noticed they offer three types of bolt face...coned, flat, and enclosed..

Is there a reason for that and what do most Defiance users seem to prefer for a hunting rifle

Beautiful actions

Bob - I've been contemplating a Defiance action and noticed this option as well. Would be interested in hearing from those who have them too. Seems as though the "flat" configuration would remove a step in the barreling process as you wouldn't need to machine a recess of any sort in order to accommodate a coned or recessed bolt nose.

Bob..Ive been looking at them also...a little to close and often

I have used recessed on all my repeater guns and cone on my single shot.

sorth any reason why in particular? Are there advantages to either one over the other?

I've never seen a flat face with a sako extractor normally they have a sliding plate extractor in the lug like Bat and Stolle panda uses!

You won't want to use a cone bolt face if you are building a repeater, could have issues with feeding from the magazine, as for the flat or recessed I can not tell you which would be better, the gunsmiths I use get in recessed ones so that is what my guns were built on.

I believe the claim is with a Sako or M16 extractorr the flat bolt nose provides more of a safety factor? Coned is only for single shot unless you have a mauser style extractor.

I have to admit that I dont think i've ever seen a rifle set up with the flat version.

My 6.5x47 1000 yard Defiance has the cone bolt nose.
Its a single shot and is just about the smoothest functioning action i've been around.I like it better than my Stolle Pandas.
The Panda has the sliding plate extractor cut right into the cone on the front of the bolt and is a very clean set up.
I had the gunsmith ask Defiance about doing that and they declined.
With Defiance you get a M-16 style extractor.
I only have about 600 rounds on my Rebel so far and the function has been flawless.
Had more than a few top end ladder tests without a hitch.
At some point and time im going to build another 17 lb "light" rifle.
It will be a Defiance Rebel action without a dought.

I have two Defiance long action repeaters.
One with a 06 bolt face and one with a mag bolt face.
Both have the enclosed bolt head.
And the same smoothness and workmanship of my single shot.
Its like handling a work of art.
They should be done this year.

One of the things alot of people miss about these actions is the primary extraction.
Defiance uses a 5 axis cnc milling machine and the mating surfaces are "matched".
When the bolt handle is part of the bolt.
Its the right way to do it.

Can't imagine why a cone bolt would impair mag feeding. Case head contacts the bolt face, not the coned lugs. My 6.5 CM has a coned bolt and feed excellent.

Joe/Dave: They look very nice!

Thanks guys! Seems the M16 extractor is a good way to go?

Bob,
Its just a longer,heavy duty version,of the Sako.

I had my repeaters sent to Dave Gentry for the M70 safe install.
Got them back and they look great.
Have all the rest of the parts.
Just a waiting game now.
And I have still have to make up my mind on the mag bolt face.

Yes. I've got 3 Defiance actions w/M16 type extractors....well built actions/good CS.

Can anyone tell me whether the Talley lightweight alloy rings built for the Nesika Bay actions will work on these?

Not just the lugs are coned, the bolt face lip is also, with the bolt face lip being coned there may not be enough of a lip to grab the shell from the clip.

Depending on the bridge style you get, I have two different styles, with the one style Nesika Talleys fit, with another style Rem 700 fit but hang in to the port area a bit and I think there is a third style but not sure what kind of rings they take. With the Remington bridge my gunsmith usually machines the front of the base a bit so it does not hang in to the port area and makes the fit/finish a little better.

Nesika action with flat bolt face seems to work well.




Don't know the advantages/disadvantages though.

I seem to remember that the bench rest guys liked the cone shaped bolt nose saying that they felt that shape helped feeding. Maybe dave7mm or butchlambert1 would know why they preferred that shape.

Stoney/Everyone: Thanks for the info.

Got to get you out of the antique mil surp action mindset..........
