I have a question on my sbh hunter 44mag. My gun is on its way back to ruger for the 3rd time for the same problem. The screw that holds the ejector housing on keeps sheering off after 300 rounds or so. The last trip in they replaced the barrel. Has anyone ever seen this or maybe knows what the problem could be. I�m at my wits end any replies would be helpful.



Thanks bronco7,

would a belt mountain base pin help? i'm not sure, but they are great to keep the base pin from sliding out under heavy recoil. they lock down with a small allen screw against the bottom of the barrel. i had to use one on a 4 5/8" super blackhawk i had for a short while, but i'm not sure if it'll help with the ejector rod housing.

Im not sure if a base pin would help. Whould that help with the guns the lock up? I should also explain better its sheering off very clean and even with the barrel. Im using a 240 swc over 21.5 gr of 2400. I think the ruger should handle that.

The only time any screws sheared for me was when they became loose. The ejector housing screw has to be tight. Degrease and locktite it, then make it very tight.

Thanks for the response I'll keep checking the screw after every couple of rounds for a while. I wouldn't think they would get loose that fast three times in a row but I guess you never know. I have had three sbh and have never had a problem with them. I have shot many more loads threw those without a hiccup.

21.5 gr of 2400 with a 240gr boolet isn't really all that hot. I hope you get it worked out. derf

When I first shot my BFR, it got pretty dirty so I wanted to pull the ejector housing. I tried as hard as I could to get the screw loose with no luck. IT WAS TIGHT! After shooting for a while, I found it had come loose by itself. I had to locktite it also. I still check everytime I clean.

Yep,
I broke one screw and bent another. I had the barrel bobbed on mine and when the gunsmith put it back together he cleaned everything very well and then used Red Loctite. I haven't been able to get it loose without using some heat. I've tried Blue Loctite and it doesn't work. I would think that epoxy on the housing like a scope base would work too.
Good Luck,
Jeff

bfrshooter has it nailed. What is happening is the screw comes loose from recoil and when enough slop develops in the screw hole the rod slamming against the screw shears it off. You have to loc-tite the screw. The barrel was replaced because after time the hole becomes wallowed out..............JJ

Thanks guys you have all been a big help. One last question does the fact that the ejector housing being steel {heavier} versus the other sbh being aluminum has anything to do with it?

The aluminum housings are not as heavy and therefore not as prone to quickly shearing the screws as do the steel ones. You would however, have a better chance of deformation to the housing and barrel if it were left loose for an extended shooting session.
