I thought I'd post here to see if anyone else has heard of this.

My brother bought a Guide Gun - probably around 2000 or 2001. It was new when he purchased it. He guided in AK for a few years and wanted it for bear. I bought him a couple of boxes of Garrett Hammerheads 540 gr SHC +P. He's probably shot only 15-20 rounds out of the 40, just for practice. All of the other ammo that he's put through the gun is standard .45-70 store bought loads (mainly Remington 405 gr).

I'm trying to get a picture of the bolt - will post that as soon as I get one.

Has anyone seen this?

Do you think it's related to the Garrett Ammo? We're not blaming his ammo, stuff happens. His site does claim that the Marlin has to be made after 1998. I don't know the serial # or when the gun was made, just purchased.

Thanks.

I have never heard of this. Get us the first two didgets of the serial # and pics of the bolt. This should be interesting for sure!

It would be nice to see some of the fired Garretts brass too maybe the base and a close up of the primer. Excessive headspace maybe?

I know he only fired a few of the Garretts, but I would never feed my gun a steady diet of them. My shoulder couldn't take it anyway!

I never heard of this happening,but I suppose if the bolt had a slight defect or micro crack in it then the +p loads will bring it to light.
The only difference I know of in the 1895 action is the early non-CBS actions can take a slightly longer OAL.Will be interesting to see
how this pans out.I have also seen where factorys have made mistakes in ammo production.Seen a shooter a few feet from me firing a Colt SAA replica 45LC blow half the cylinder apart and blew the backstrap right straight up from a "factory" load.Sounded like a 44 mag full tilt load when it was suppose to be a cowboy load.(somehow nobody was injured)

Which bolt are you referring too?...........the Breech Bolt, or the Locking Bolt?
The Breech bolt is always in COMPRESSION, and the Locking Bolt is always in SHEAR............

What changed in 1998? I'd be interested in the pictures too.

I'm working on those pics. My brother is floating the Smith River in MT right now (freezing his butt off, having a great time I'm sure). While I'm working away....

As soon as he gets home I'll pester him for some pics. I haven't seen it yet either, so I'm not sure exactly where the crack is.

That may have been when the ports were dis-continued...............Not really sure, though.

My brother got off the river last night - so I'm hoping to get some pictures tonight.

Will post them as soon as I get them - I'm as interested in seeing them as you are.

Bill:

I currently reside in the liberal bastion of Missoula (liberal for MT, tame for the West Coast though). My brother lives in Helena.

I love White Sulphur Springs. I would move there in a heart beat.

Off Topic....

I lived in Butte for three years while attending Montana Tech (School of Mines). Those three years were some of the most enjoyable in my life.

The folks in Montana are some of the best people you'll ever want to meet.
