Show Your Custom Rifles With Granite Mountain Arms Actions

[JD Noblin]

I bet the members of this forum have some fantastic custom rifles build on the Granite Mountain Arms action. Post up your GMA rifle and tell us a little about it.

Below is what I call my "heavy plains game" rifle in 338 Norma Magnum. It's built on a GMA African Magnum action with a 24" McGowan barrel milled into a sporter octagon barrel. The wood is Turkish Walnut and the action finish is rust blue with screw heads, extractor claw and trigger in nitre-blue. The bolt shroud, pistol grip cap, and rings are color-cased. The action has accent engraving and some minor gold lines. This rifle shoots a 250gr Northfork soft at 3015fps. I've taken a variety of plains game with it with 99% of the animals dropping to the shot, including eland.

Those look great! Love the color-cased actions! Can you tell us more about the 505 and your hunts with it?

I don't own a 505 but am thinking about building one. My favorite safari writer is John A. Hunter and one of two cartridges he loved the most was a 505 Gibbs (the other being a 500 Nitro Express).

My GMA double square bridge Mauser in 404 Jeffery. Don’t actually know which smith built it, but am told the stock was done by Joe Smithson. Feeds like a charm and is sub minute with Swift factory 400 gr A-frames.

I really like the grain of your stock. Nice mixture of streaking with incredibly straight grain. The whole rifle is very business-like. It was made to be a rifle that's used instead of simply admired. It would not surprise me to see something like this on the shoulder of a PH tracking buffalo. Well done.

Many thanks @BeeMaa - I feel the same way, but you still made my day! When I took it into Matt at Hill Country Rifles to have the scope mounted, he said the craftsmanship was on par with our very top-gunmakers and also made your exact same comment about the stock having the proper grain for maximum strength. I appreciate your thoughts.

Beautiful rifles, all. Had a chance to stop by Matt Robert's shop in VT earlier this year (MNR Customs). He's doing quite a bit on GMA actions. I keep weighing one of his Hatari rifles in .416 Rigby or .404 Jeff vs another safari....

Left hand GMA actioned .505 Gibbs made by Wayne Jacobsen. My one custom rifle that I ordered. Other custom/semi custom rifles I bought used. This is my favorite.

Damn, look what I found!!! The original listing for my 404 Jeffery, complete with description and professional photos, far better than I could ever do!

Those are some nice varmint rifles, boys.

I kid. All are beautifully done. . . and much more practical.

That's a real show piece (cannon) you got there @RR 314 - absolutely love the grain and the scrolling!!!

Yes sir. Wayne executed it beautifully. I do want to take it for one trip. Just need to hit the anabolics and weight room first.
