I have had several bolts in the shop lately with dual ejectors. Both with M16 extractors. Guessing this an attempt to lower the ejection angle of a fired case. Any experience or thoughts about this? Just curious if it works.

GUNSMITHING SERVICES: Dual ejectors for M700's with AR15/M16 Extractors
Problem Statement: Ejection with a factory bolt M700 fitted with an AR15/M16 extractor has always been plagued with an annoying problem. The issue is the ejection angle of the case body as it pivots on the extractor claw and attempts to leave the loading port of the action. The factory...

Interesting ... I didn't know this was a thing.

Some time back I had Prairie Gunworks in Winnipeg build me my "high country rifle". A Titanium SA M700 clone in 7-08 Ackley with two plunger ejectors fitted into the bolt face, along with a M16 extractor.
Only abut 300 rounds through it so far, as it is a hunting rifle and not a varmint rat rifle, and no ill-effects from the dual ejectors. I did not specify this feature, was a bit surprised when I received it, but it functions absolutely 100% every time the bolt cycles.

A solution to a non existing problem. I had a large frame gas gun with dual ejectors never
gave me any issues but neither has anything I owned with a single ejector.

Do you own any Model 700's that have an M16 extractor and a big windage knob?

Its a good idea for sure. They bounce right back in there without 2

2 ejector marks for the price of one

Why?
What Old Navy said. Tommy Mc
Back in November I bought a Kauger PRS short action.
Decided to grab a magnum bolt head for it since the price was right.
It has the dual ejectors standard.
The .473 bolt head has a single ejector.
Bolt disassembles pretty much the same as a Bighorn.
Bolt heads change out in under a minute.
Small firing pin too.
I really like the action.
It's based on the 700 footprint. Hooded recoil lug so it doesn't show.
Primary extraction is fantastic and they left a hood over that too. Should keep some dirt off of the extraction cam.
181 rounds through it so far...

On a 700 your stuck with doing what you have to do if there is a problem. I sure would not want to see this on a custom action. Theres a lot you can do with ejector and extractor location ( not just copy remington). When you put 2 ejectors in you reduce the surface area of the bolt face which increases the load the rest of the bolt face sees, so you will now get ejector marks at lower pressures than before. Id like to see most custom actions reduce the diameter of the ejectors for the same reason.
I hope this doesn’t turn into the same thing as men’s razor blades have over the years. Pretty soon, you’ll need five of em.
I use dual ejector bolts with small firing pin on AR 10 in 6 5 Creedmoor and my favorite the 308 win. So how do you think I run 200 gr SKM 710 BC at 2621 ave fps 12.4 S/D in an 18" 5 r Proof 308 Win barrel. An adjustable gas block is a must...also put a rug cushion on your shell deflector and your cases come out hot and perfect. Heavy loads in tbe 6.5 Creedmoor AR 10 with a 24 " barrel were up to 2940 fps with 140 grain...but I prefer the 150 SMK at 2850...I run the same or close to it loads in the bolt guns as the ARs...but I don't have a clue as to why on a bolt gun that you'd need two ejectors...I put a low power spring on some of mine, so the brass doesn't go flying far, far away. AND...it doesn't side load my 6 dasher cartridge with excess pressure while loaded in the chamber...good theory...huh? ...but who knows for sure. Remember ...Some are outside the box...way outside. Plus why would you what or think like everyone else, chart your own coarse... and experiment with what others have discovered,..is it for you? Dual ejectors guy? ...sometimes...
