Head spacing by sw!

[rexxer]

I'm trying to get the proper head spacing using sw methods in the hint and tip section. Everything worked fine except my primer now sticks. Even if I recock and fire again. The inner part of the primer,silver in color is now raised 1/32. Which way do I adjust? Thanks Rex

Sounds as if the bolt is not pushing the primer in the BP tight . Try backing the BP out about 1/4 turn or less and see if the bolt still closes easily, if it does the barrel needs to be adj into the action a little more. It is hard to tell someone how to get it just right a lot of it is feel and how the bolt opens and closes.

Thanks Joe
I tried but it didn't seem like it made a difference. It does look like I have a small crack in the bolt face primer pocket. It also seems like I have alot of slop between the bolt and the primer flange before fireing.

Rex..........did you get the primer to go 2/3 of the way into the pocket in the breech plug? If you do that, when the "primer holder" on the end of the bolt is touching the breech plug, the rearmost part of the primer should be about touching the actual face of the bolt. Now, when you tighten in the breech plug and then tighten up the barrel (on the closed bolt with the primer in), you should then just a degree, loosen the barrel and tighten the barrel nut. Make sure the bolt opens and closes OK.

The bolt face crack should be fixed. The end of the bolt is replaceable. It sounds like you have to much head space . The primer should be as Richard said at least 2/3 in the BP nipple and the bolt should be pushing the primer in. there should be no play when the bolt is locked in the fire position.

Savage refers to that piece as the "firing pin support." $15.00 shipped.

Do you guys buy these parts directly from Savage? I haven't seen where you can order from.

I will try again today to set the head space. I thought I had it to where the bolt would just close.

1)Is this problem when firing a full load, or are you just snapping a cap?

2)Is this a new breechplug, or have you drilled it out?

3)If you take a primer and try to insert it into the BP nipple does it go in very easily?



Please note that that is just a sketch and it has been a long time since I looked at the ML-II bolt face.

If #1 is only snapping caps, this is common, especially if everything is not broken in by firing.

#2 & #3 if the BP is new or drilled out to a large diameter, the primer may not stay back against the boltface until you have a number of shots through it to build up some carbon.

I think Edge nailed it.

When I first got my 10ML I had to pull out primers that I had snapped (no load) with a pair of pliers. Once I hit the 100 shot or so mark, they quit sticking.

1 just snapping caps

2 This is the original breech plug,I put a small chamfer on the primer pocket and polished the inside. primer goes in 2/3. With a semi=light push with finger it will go all the way on.


3 I would say it goes in fairly easy. I just polished all the carbon out so I will let it build back up and see what happens. Thanks to all


Nice sketch Edge!

There is a parallel between cartridge cases and the 209 primers. Upon firing the cartridge case expands tightly against the chamber and then almost immediately shrinks back some where it can be easily ejected. When I first started investigating how to get the primers to not disintregate upon firing "challenging" loads, I noticed that the primers would not go even quite 1/2 way into the primer holder as the gun was set up. So I loosened the barrel nut and tried to adjust the barrel to where it would go to the primer holder in the bolt. This crushed the primers. I then did the obvious and tried pushing the primer into the handheld BP with the primer in the bolt primer holder. I couldn't get it to go down all the way. The size "C" drill bit opened this up and I not carefully drilled it out to where it would just touch bottom of the BP primer insert when the bolt face just touched the BP. This is a very loose fit but the primer is fully contained within the BP primer insert except for the small amt of the primer being held by the bolt face. Upon firing the primer expands and contacts the side of the primer insert space in the BP and then immediately contracts and is easily removed. Case in point: I used a 11/46 4759/2015/200SST load in my 40 cal for hunting. This is a super hot load (>50,000psi), too hot, but my primers came out looking new. Even with all this pressure! Try that in your unadjusted Savage and see what the primer looks like. All my barrels (4 PacNors and 1 Savage are adjusted accordingly now and the primers always come right out and look new when they come out. My primers have a loose fit going in and coming out.
Hope this helps someone.

Winchester primers are fine in my gun but I have to beat CCI's out so I don't shoot them anymore.
