Rifle actions Which one?

[Edd]

I have always believed that the front of the bolt lugs should be .010” lower than the bolt face. I haven’t measured a lot of actions, maybe a couple dozen. Of the actions I’ve measured, a Surgeon is the only one that measured that way.

 

[Ironworker]

What cartridge are you going to use and what type of finish on the metal?

Varmint/predator Rifle ,either 22GT or 22 CreedMoor 26" bbl I'd want to shoot 69-80 gr bullets

 

[DaveTooley]

Must be a newer version as they never accepted them and the one I had didn't either. Once a smith had it in hand and got the measurements then I could order shouldered barrels but they were for my rifle only. Not for every Surgeon. Did they change it over the years?

All but one were the Oklahoma actions. My personal action from AZ measures out the same or at least close enough.

Mine was an Oklahoma action also and my buddy who knew Preston from the beginning has at least 8 Surgeons and couldn’t get them but if you found they do then that’s another plus for Surgeon.

Why? What is the benefit?

I don't know if there is a benefit but actions have dimension specs and, if I was making them, that's how I would do it.

The distance from the face of the receiver to the bolt face would be the barrel tenon length and the go gauge would be flush with the tenon surface.

 

[Dan-Schenk]

That looks nice, plus the price won't break the bank. Do you have one?

I have the single shot, and have been very pleased with it. I also like that the recoil lug mounts using a hex fit to the receiver.

For Varmint and Coyotes I would choose a Zermatt TL3. They take Savage prefits with a barrel nut or Shouldered prefits.

Out of the three you mentioned any of them would be fine...

+1 for the Zermatt/Bighorn TL3. Excellent action. Easy to swap bolt heads , they offer push feed or controlled round feed bolt heads if you call Ray. Their pinfall can sometimes be a little lighter than the recommended 240-250 but they offer cocking pieces of various lengths to correct it.

Pinfall, meaning a light firing pin strike on a NIB $1400 dollar action ?

No light strikes, rounds go off just fine but for benchrest accuracy .240-.250 is recommended. If you don’t require that kind of accuracy then you’re fine.

 

[Rob01]

Have had my TL3s for years with multiple barrels and calibers in small and large rifle primers and never any issue with light strikes. Also accuracy is very good. No worse than any other custom being spoken of.

.240-.250 is recommended for the larger Remington firing pin diameter. You can get by with as little as .170 with the smaller diameter pin, but with the way they are setting them up now even my Diamond gives .205 of fall .

My SDs have been 4 or better on 10 shot strings and 5 shot groups with BR variants are demanded to be sub .250.

It might matter if you were trying to break an inch at 1,000 yards, but for the rest of the world pop minus the 4 or 5 people that can do that, it’s just not worth mentioning.

To be clear, I used to worry about this too but it’s a non issue. Never had a TL3 new or old that didn’t shoot very very small.

Pinfall, meaning a light firing pin strike on a NIB $1400 dollar action ?

Running on about 20,000 rounds through TL3s and never had an ignition issue, poor accuracy or less than excellent SD.

I even considered adding some fall to my last one out of curiosity and my smith talked me completely out of it because it’s a non/issue. I even got a second and third opinion and they said the same.

Attached is the post 200 round LD target from my previous coyote rifle build. It weighs 10.1 pounds, forend is 1.4” wide and it gets shot off a bipod. Does that make you feel better?


Someone will ask…. I chose 32.1

 

[G7BC]

Yep. Wasn’t saying you need more pinfall but another plus of the TL3 is if you want it, it’s easy to do.

 

[Ironworker]

I wonder what the "Pinfall" is on my Terminus Apollo action?

And the analysis paralysis starts. Lol

 

[TaperPin]

. . . need to get out and shoot at more coyotes

Have you shot any lately?

 

[Delfuego]

Defiance, Surgeon, Impact, of these three for a varmint/predator rifle ?

Brother, they are all nice. Actions and rifles have come a long way, almost all of them are really well made, even the budget ones. I kinda go by the company behind them now. How they handle things after the sale can be the difference between a bad experience or customer for life.

I would add Kelbly's to the short list, great product, great people.

 

[Alex Wheeler]

.240-.250" is recommended for modern designed actions, the original Remington spec was .275. Bordens, Kelblys, and Bats all shoot best .230 and up. But I stay above .240 because I have seen accuracy problems in the .230s. Of course other factors play a role in how much energy you need. Es or Sd are not what we look at in ignition. It has be be real bad to show up in es/sd. You will see it first on target, usually in the form of vertical fliers. Wont happen on every group, and can be tough to diagnose. Its more common than people know. I have fixed a lot of rifles without even seeing them just by seeing targets and telling the guy he has ignition fliers. A new trigger hanger or spring is usually all it takes. It shows up much worse at long range. We do seem to be able to get away with less at short range.
