New found love for the Long Action flat back

[ninner]

I just traded a fellow member for a Long action flat back receiver with a Factory 112 small shank stainless 300 RUM barrel, the one with the on/off brake. The rear flat on the receiver is level so that is a plus. What I can't believe is the feel of the trigger I'm not sure who tuned this 3 screw trigger but it makes any accutrigger I own feel like a serious downgrade. I'm not sure if I'll stay with the RUM long term but if I can find some semi affordable ammo or brass I'm going to at least see how it shoots. I was at Cabelas Monday and the only ammo they had for it was $61, Too rich for my blood.

Does anyone know the time frame that Savage was building Small Shank 300 RUM barrels with the on/off brake?

Back to the action,
It was built in 1987
I had one years ago but that was before I did any work myself.
Are there any downsides to building on these actions?
I like the feel of the metal safety.
The bolt has a screw slot, Can it be replaced with hex? Should I?

I'm right there with you. I put a timney on my long/short 110 and it's the best trigger I've ever handled. Accutriggers are great for what they are, but that older setup lends itself to even better tuning.

If you can get it out, I would replace the screw/fastener with a hex (easiest)

Hate slots, hate philiips. Love square, hex is ok, torx is sort of ok but I don't like it. (IMNSHO)

Ninner,
Yes, the slotted BAS on the rear of the bolt can be replaced with the more recent hex version. I just completed the exact swap you are asking about on a flat back long action chambered in 7 Mag. It also had a three screw factory trigger identical to the one in your photo. I didn't have a parallel bladed screw driver large enough to fit the slot, so I put multiple layers of painters tape on the largest flat blade screwdriver to create tight fit. It turned off very easily compared to the recent battle I had with hex BAS that must have been factory assembled by a gorilla. If that didn't work, I was prepared to use the edge of a 12-inch piece of spare bar stock I had lying around that fit the slot perfectly. Good luck! :smile-new:

I ended up putting a quarter in my woodworking vice and it worked perfectly to unscrew it I will probably leave it alone.

The receiver s/n shows 1987, but the 300 RUM did not arrive on the scene until much later

The steel rule from a combination square is a perfect fit in the slot. :p

Bill,
I appreciate you sharing that bit in information. Thank you and I'll keep it in mind for next time.
