So, I recently took delivery of a thing - is about all new to me - I never had a Remington 700 action before, never owned a 7mm-300 Weatherby before, never one a "custom" barrel before. So I have some questions that might be answered here?

So this magazine box has a tab punched out of it and a small screw into the receiver that appears to hold the magazine box in place - I have seen similar on the Numrich website - appears to be for an ADL version - does that sound correct?

Which version of trigger is this? Internet chatrooms say it is a Remington Walker trigger, a Timney trigger and a "Timdeez" trigger. I am presuming it has to be one or another?

The barrel has the letters "DH" stamped on the top - above the chamber area - any ideas what that might mean - the maker? - who would that be? EDIT: a PM to me suggests that might be the mark of David Henry - "a reputable gunsmith from Southern Alberta".

The barrel appears to have an integral helical brake - or the maker did an uber good job to join two parts together without a seam.

For those that prefer a visual comparison - a new 308 Win brass on left; a new 458 Win Mag brass in centre and that 7mm-300 WBY on the right.

I'm no Rem700 expert, but I do own one.

That trigger looks like a Walker to me, based on the grooves in the face of the trigger.

And my BDL magazine does not have any tab/screw like that, although its a relatively new rifle (2010s vintage IIRC) so its possible that was something they just got rid of over the years to save $$$.
 
From closed bolt face to muzzle is about 27 11/16" - so deduct circa 0.125" from muzzle to internal crown, the barrel is probably about 27 9/16" (70 cm) from closed bolt face to crown. Not the sort of rifle to be dragging through willows or a swamp, I suspect.

Yes this one also has grooves on the face of it - is also circa 0.050" wider at bottom end of trigger compared to where it emerges from the trigger box body - so like "splayed" or similar.
 
A brand-spanking new Remington 700 BDL in .22-250, bought at the Home Hardware in Hay River, NWT back in 1984, had that magazine screw. Never had an ADL, so don't know about that, other than the mag. housing on an ADL is shorter than a BDL as the ADL sits on wood, whereas the BDL sits inside the triggerguard/floorplate assembly. I always figured that it was to keep the mag. housing in place when you removed the trigger guard / floorplate assembly.
Never heard of a Remington "Walker" trigger before; it looks like a factory Remington 700 trigger [of course designed by, as was the entire rifle, Mike Walker] to me.
 
Looks like a factory trigger to me as well. I would have suggested DH could be David Henry as has already been noted. Now the question is are you going to neck down 300 wby cases or neck up 6.5-300?

Walker is what they called the old factory triggers. The newer ones (2007+) are known as the X-Mark Pro.

OP can you open the bolt with the safety engaged, or does the bolt lock up when the safety is on? If it locks up, its a pre-1982 trigger, if not its a post-1982.

I just tried it - the bolt opens whether the safety is forward (on "F") or back (on "S") - so after 1982, as per your information. It is not obvious to me how a bolt lock had been defeated. From your link, the post-1982 triggers do not have that bolt locking "bar" - this trigger does not either - although the receiver has a slot for it and the bolt has a groove cut to receive such a "bar", if the trigger had one. Serial number on Action is B68794xx - so that might be a clue when this was made - I am still trying to find an Internet resource that matches Remington 700 action to manufacturer date - but might be all wonky if this is a "custom" thing - I have no clue what is original to the factory rifle, and what is after-market "improvements" to it. This particular trigger, in it's current configuration, may not have left the factory, on this action.

I am working on more than one Parker Hale that is similar - a bar on the trigger to lock the bolt shut when on "Safe" - I am not 100% sure about the utility of that - but was apparently a thing at one time to have the bolt locked shut when the safety was on - is really about the only difference on Mauser 98 between safety lever fully to right versus straight up - the bolt is locked shut.

From what I can gather they made the actions with the slot for a while after changing the safety design, so sounds like maybe your action is from those in-between years. Or maybe its been pieced together from multiple rifles.

The barrel is custom no doubt, but you might be able to get info on when the action was made. IIRC Gravel Agency was the importer for Remington before they went through bankruptcy, they were able to tell me when my rifle was made and what caliber/model it left the factory based on the serial number, but that was a 2013-made gun so their records/info might not go back far enough.

Doesn't hurt to shoot off an email and ask though.

Neck down or neck up - I do have some 300 Weatherby cases, but do not have any 6.5-300 Weatherby - so is easy answer - eventually I will be "necking down" - however, the rifle showed up with 123 brass - so not terribly likely at age 69 that I will be wearing those out. However, is stuff here that give me choices, I guess - or at least a "Plan B". Having choices, is usually better than not having choices.

Nice cartridge choice, beats a 7PRC I bet. What twist rate?

tape the holes up and have at it. Long rifles make better walking sticks )
 
Potashminer, Here are a couple links about Walker Trigger groups that I found when I got a 1960 Rem 722 in 308. Hope some of this helps you.
http s://forum.accurateshooter.com/threads/remington-722-safety.3745976/
and http s://www.700rifle.com/threads/remington-walker-trigger-explanation.19289/#post-68787
I found the age on www. remingtonsociety .org - Lots of info there. And jbelk ( Last seen - Jun 13, 2023 on 700rifle .com) had an instructional-pdf on how to "fix" the Walker to 'make it safe' which describes also the 'Safety issue' on them. Here's the bit about the safety - ". . . Remove the bolt and look down in the rear tang at the sear. If there is a stack of four parts, the outer housing and the two sears, it's an early gun and should be treated with special care. The more modern sears are chromed sintered metal and of one piece.The second test is to see if it has a bolt lock safety. Does the bolt open easily with safety ON? If so it was made after 1982. If you have a bolt lock gun, cut the lug off so it's defeated. Just grind off #32 Fig 1 of the patent. . . . "
AND a YT vid on this also - http s://www.youtube.com/watch?v=Nz48KyiuGi4&t=1s
One more thing I found in his pdf -
Walker with Description.jpg
 
PS - I've had my 722 for 3+ years and ca 200 shots with NO A-D . . . but it's only 64 years old, a bit younger than me.
