Poor Man's Drop Port

Rem 700, WHY NOT???

I just opened up a package from Brownell's that contained one of the "new" rivetless 700 extractors...... this pertickler rifle also has an epoxied in single-shot floorplate.

I'm lookin', and got to thinkin'......What would keep a person from milling a drop port in the floorplate and installing the extractor 90degrees off? Bottom, for a dropper.

It's late, it's dark and windy and I'm not going down to the shop.... but any knee-jerk reactions I can look at in the morning? Why would this NOT work? Might have to spin out a liddle metal and of course the ejector needs to be removed or even plugged, but am I missing something obvious here?

If I recall, the inside of the bolt nose is milled in a "pattern" or sorts that keep it positioned. To make it "drop", you may have to change the "pattern" so it releases straight down, not to the right side.

I'm sure Stiller can explain it better than me.
 
It will work. Sometime in the recent past someone described the series of cuts that you have to make in the bolt nose. Do a search and maybe you can find the info.
 
My old 722 (.222)has no rivet, and it is the ejector that indexes the extractor. I found this out, years ago, when I got the bright idea to leave out the ejector. I soon found out why that was not a workable idea. The extractor rotated, and I had to pull the bolt to get the case off of the bolt face.
 
I have a new remington action that uses the rivetless extractor. I removed the ejector plunger and spring and have had no problems at all. It is a standard bolt face though.

Al,

There was a 7mm Rem Mag at the 2008 Nationals in Byers that was converted to a drop port. He bought a bolt from Kiff that had the Rem extractor in the correct spot for a drop port. The shooter stated that it took quite a few tries before he got the drop port plate to function well.
He shot very fast and it worked great.

I have opened up a 308 boltface to accept a magnum Rem extractor. The info is available on cutter sizes, offset of cutter. You could start with a smaller boltface bolt and bore and re-machine the snout with the extractor where you wanted it to be. I've also thought about doing it with a Savage bolthead to one of my converted bolts, I think it would work fine. Remove and ignore the Savage sliding gate extractor.

Hi All , I came up from my shed to see this post ,i have been working on just such an animal this morning .. A Pal wanted a Heavy Gun for 1K after shooting my custom built dropport but did not have the funds for a new action even though there is none configured like this comercially ,so we set about making one from R700 that was in 270 win ..It's chambered up for a 300wsm but the port is to take up to 300 ack, works perfectly ,loads easy .. Sitting behind the out fit i think i could shoot a right bolt set up fast after i make a loading hopper to suit.. Pic of a budget Gun..JR..Jeff Rogers

Wonder if it would be easier to part/cut the bolt nose and silver solder into proper drop port position, rather than fill and re-cut nose for new extractor position. Could return nose to original position if needed/wanted.........Don

You don't need to "fill" the bolt nose if you start with a bolt that is for a smaller cartridge head than you will use for the finished rifle.
To remove and reattach only the small snout section that has the extractor in it would be nearly impossible, I think. Silver solder requires a lot of heat which could lead to distortion and undesirable changes in the heat treat condition of the lugs.

Thanks guys :)

I stopped by the shop on my way in from work and can affirm several of the comments.........

Yes, the rivetless is kept from spinning by some abutting areas. Were I to use a rivetless I'd first try building up these areas with metal-filled epoxy. I can't imagine it being a problem.

BUT, I have an old 700 riveting stud..... and I have a small lathe/mill. I will probably play with a rivetless to get the angle and then redrill and install a riveted extractor if I encounter any problems.

I will not ever silver solder anything on a bolt closer than the root of the bolt-handle.

Thanks to you all, you've answered my question to the tee.

al sir

i think jay is talking about my rifle,it works well but still has some minor hang ups once in a blue moon with different length rounds but all in all it is a joy to use .the floor plate is kind of tricky to fit and locate fore and aft in so you can throw a round in with out a fall through but is possible because in my case i bought 5 plates to play with and machine and used every one before i had it right.good luck to you sir. tim in tx

Thank you Tim! :)

That's exactly the sort of real-world experience I can relate to...... now maybe I can get it in only three tries!

LOL
