Mr Sgr218, I have a couple questions for you. First, do you do this gunsmith work as a hobby or is this your trade? Second, how long have you been doing this? Third, are you self taught or did you get schooling and or an apprenticeship? Your videos are clear and concise, which make them interesting to me and many others. Thank you and happy chip making.
Hey awesome videos.. I have been thinking of getting into gun smithing too.. was just wondering if you trued the front face of the action where the barrel mates?
Superb job,do you rely purely on the retainer compound just to hod the sleeve and bolt handle? I think I personally would have pinned the sleeve and the bolt handle in atleast one position,just belt and braces.I know the retainer (Loctite 638?) is extremely strong,I used to build spools for hydraulic valves suing it and never had a failure.I'd just be tempted to mechanicaly fix the parts in place aswell,just me.
Yes, the bolt handle is welded to a sleeve and then epoxied on the bolt body. I use a 2 # hammer to test and have never had a sleeve let go. The silver solder job will break loose first.
I don't believe there are any. I set this up b/4 Pacific made bolts. Either way is about the same cost. I have seen the raceway dimensions on he 700's anywhere from .698 to .704.Most have about .006 slop or more. At .006 when the rear of the bolt comes to the top of the raceway from the pressure of the trigger and or cases in the mag.box the top lug of the bolt does not touch the integral lug of the receiver. Therefore you are using the bottom lug and not the top lug. Makes for bad harmonics.
I respectfully disagree about the harmonics being an important issue. We tested 700 and custom 700 rifles with ultrasound, strain gauges, as well as 2d and 3d Finite Element Analysis ´FEA´ Turns out, this bolt slop reduces multiple stress points and the fact that in most factory rem rifles only 1 section of lug is touching the corres. receiver lug limited the stress to one area, thus reducing ´harmonics´ aka vibrations. proveing that vibrations behind lugs plays no role in accuracy. HOWEVER.
Improper lug alignment, which is found in most all factory rifles including Savage does create an accuracy problem that has nothing to do with harmonics. When lugs are not flush and 1 is touching this allows the bolt to move to 1 side during the firing/pressuring up of the case. This back pressure forces the bolt lugs to then mate. The major problem is that the case follows the bolt in its movement. The case swells on one side and pressure is released until the rest of the case swells
finally sealing the chamber allowing remaining pressure to flow out the muzzle. This type of blow back does not drop chamber pressures it increases them, thus severely limiting your cartridge´s performance in all areas including case life. Bolt sleeves when installed right absoloutely work as do our oversized 700 bolts at keeping the bolt perfectly in line. However, when done correctly the bolt is not smooth. Think about it, it cant be. If the bolt has 1/2 thou on either side it..
can not be smooth. I laugh when i see a guy pick up a rifle, cycle the bolt and say oooh thats so smooth haha. Sloppy is smooth. It means your bolt is dancing around like Britnay Spears *before she had kids*! Anyway, we have built rifles for the military for 15 years and BR rifles for 25 years. We have aerospace engineers working with us and use building/test equipment from NASA. For our 700 military rifles we overbore the raceway to .706 and use .700 bolt. We have a secret that keeps our lugs
@sheaver6987 Shut up you pompous ass. I have a several bench guns that have SMOOTH AS GLASS actions (ie:2 BAT's, a Neseika, and a Stiller Viper) with super tight bolt to raceway tolerance. If the finish of the bolt and raceway are SMOOTH than it will operate that way. Military rifles are designed with excessive bolt clearance as they are used in the FIELD! If they had .001 bolt clearance they would bind at the sight of dirt. You wouldn't know good machining if it slapped you in the face.
@sheaver6987 And what the hell do you mean "when done correctly the bolt isn't smooth"? If it is flopping around it will be anything but! Besides, I want to know what gunsmithing firm building top bench rifles has aerospace engineers and NASA test equipment. Last I checked, Gordy Gritters, Dave Tooley, Jim Borden, Speedy Gonzalez and the rest of the top smiths were putting out the winning rifles? I think you know little and speak much, probably a secretary.
If you install the kiff bolt it would have to be re-head spaced because there may be a slight difference in bolt dimensions. This would be a normal situation replacing any bolt would require this.
I was wondering i am looking at getting a Remington 700 in .270 win. IYO do you think that the R700 is better than the Mossberg 100 ATR or 4X4 in .270. I do alot of hunting every year and i shoot anywhere from 25 yards out to 350+.
Yes, it makes it more smother and easier. The object of doing it is that Rem.700 have too much bolt slop. With .006 slop in the raceway when you close the bolt the trigger and or shells push the bolt to the top of the raceway and the top lug of the bolt comes off the integral lug of the receiver and you are using only one lug. It also sets up some harmonics that you don't want.
ok. im just getting into shooting really and have been looking at the rem 700 but im not in any sort of competitions or anything. im just going to the range for the day kind of shooter. im just curious if its a disadvantage of the rem compared to other rifles.
The Remington 700 is a good choice. If later your thinking of installing a new bbl or accurizing it alot of after market things will fit the 700. ie, trigger, lug, etc. All actions have excessive slop from the factory. For example the M-70 Winchesters are running around .012 to 015 and the Rugers are not much better. Another good choice is the Savage. Right out of the box accuracy is pretty common. Right now bang for the buck it has to be Savage. Savage has a floating bolt head which helps.

I do gunsmithing for a living and have since 1983 when my father passed away I took over the business.
I went to Remington's school but was taught mostly by my dad.

Joe,
Yes indeed.... we also true up the threads, and single point cut in the lathe, re-cut the integral lugs in the receiver and face the action.

Great video(GREAT VIDEO'S!!)
i'm not a gunsmith but i can appreciate quality work and i can see you are a master.
Stan,what are the advantages of sleeve over a replacement oversize bolt?and what are the standard factory receiver bore dimentions?
Thank you for your time and effort

PTG make a .703 bolt body which iv'e seen recently and looks very well made
comes ready cut for sako extractor.
would the correct headspace not hold bolt lugs against receiver lugs?
i recently purchased a 700VSF .308 which i feel has a lot of bolt slop(compared to sako and browning euro),just considering all options,Thanks again

How do you "glue" on the sleeve? Do you use "Green" LocTite or some simular product?

I use JB Weld and it works very well. It will withstand high and low temps.
