I had tried the 3-hole vents when they were out in my 50 cal.Didn't have a problem with them,even shot some good groups with them.Only thing they didn't last long. Well today I tried one in my 45 cal and one shot was enough.It blew the primer up and throwed power and pieces of primer out the side vent hole.Which got me on the side of my face and still burns. So if you have any I would use them in the 50 only.I know I won't try anymore of them in my 45. The accuracy was good though with only one shot,I had zeroed in at 100 yds with my old scope and this one hit,if I had been shooting at the same target in the same hole. Just thought I would give a little heads up. The pic didn't come out to good but you can see where itn blowed the side of the primer out.  |

If anyone has them either contact savage for replacements or toss them out. Mike |

Herman. Glad you were not hurt any worse. Now we know why they had the recall. Glad to see you back you were missed for a while.

Jon I read the board every day but just haven't had anything to write lately.
I didn't shoot the 45 today but 6 shots,had to rezero my scope.then shot the 3-holer vent and that was it for the day.
Did play some with my savage and tikka 308's and my 6brx,even got 2 one holers with the tikka at 200 yds.
We got to the range before daylight but it was still very foggy at 10 am.It was after 10 am before I could even see the target at 200 yds.

Herman I’m happy to hear that you only had to endure an incident and not a disaster. I personally did not get good results with the 3-hole vent liner when I tried them. After the first 20-rounds I saw the erosion occurring between the holes and stopped using them. As a reminder I kept those vent liners. There are some that are probably wondering what they looked like so I tried to take a picture of them. The three on the left are unused and the one on the right is with the erosion starting to occur between the holes.  Ed |

Herman, nothing to thank as I too enjoy when someone can provide an explanation or results with a picture, like you did. Also I thought that there are members who may not have seen these past vent liners and would enjoy seeing what they looked like.
The one thing that puzzles me is that the erosion started and is located on the primer side and not the bore side. On this particular vent liner there is no erosion between the holes bore side??

If erosion could be solved, is there any merit in the three holer? I'm wondering about a carbide bushing with three holes drilled in place of a vent liner.

Seems to me, the object of the vent liner is to retard pressure back to the primer/bolt face? Savage uses a hole of about .030" to do this. I don't personally know that the diameter of the holes are in the "3 hole plug" but looking at Herman's, they have to be at least .02 something? Even if they were .020"..........That would be .060" worth of hole vs. a single .030". The whole concept does not make sense to me? We throw our vent liners away when they get to .036" so why would you want .060"  Herman said they shot OK in his .50 so I guess them will work  Richard |

My understanding for the additional smaller holes was to assist helping the ignition of harder to ignite powders such as 4227 or slower powders like H4198. With the advent of the recessed breech plug, compliment from Edge, I don’t see a need for a multiple holed vent liner. Then there’s using a duplex load to assist the ignition of slower burning powders so there should be no real need for a multi holed vent liner IMO.

I have all my original 3-holers and this is the first I have heard this. Will Savage exchange them or should I just trash them?
I'm on only my second RW liner. Is the current Savage one-holer similar in size to the RWs?

If you have some of the 3-holers I would send them back and exchange,IMO they are not worth the effort.I just had some and got a wild hair to give them a try in the 45.
I think these were one of Tobeys ideas to start with.
I was shooting a duplex load in the 45 but even in the 50 cal they didn't last long when I was testing them.
As far as vent size in the savage one hole,I just picked up a BP and it had the vent in it and I get .o31.I picked up a couple loose vents last month and was surprized that I got .o36 with them.
I am going to take and measure some again when I go back to the gun shop.
When I get past .o35 I change them.
I think RW are .o31 not sure but at one time I think he had 2 sizes,again not sure.
I have some of the lehighs and they are good but didn't like haveing to use a differant allen wrench to take them out and in.And they last too.
As far as lasting I like the RW's better but I am out of them now.
