I am building a Rem 700 in 300 win mag. I want to put a detachable magazine on it. There are several out there, what are your recommendations?

Thanks
 
What stock do you have? If you have a BDL inlet and want to avoid inletting then PTG has the answer. $200 for a drop-in dbm with 1 mag, it uses 3.775 length mags not the "standard" AICS 3.715 although Accurate Mag & AICS both supposedly make 3.775 length
Look through my started posts for one about shimming magazines to see how you can use the standard mags in that dbm as well, it's simple.
 
i just put a PTG bm in my 700 w/ choate tactical stock over the weekend. it was a DIY inletting via dremmel and will post up the process with pictures when sorted.

though it came out good and operates flawlessly with an alpha mag, if the BM you eventually choose needs inletting, send it out to get done by folks that do it for a living.

now that i've done the DIY inletting bubba style, there is absolutely no way to ensure that all is flush on the bearing surfaces or trued when doing it yourself. the 6-10 hours it takes to attempt to do it carefully pays for the gunsmithing fees if worked as overtime at work, and gets rid of any concerns of a bubba inletting job on an ADL (no hingeplate) model. if ever to do it again, i will send it to get inletted properly on a programed mill so that everthing is trued.
 
Grant,

I haven't picked out a stock yet, I am thinking about a laminated wood stock and glass bedding it. I have done glass bedding before so I know I can make that work well.
 
Out of curiosity, if the surfaces weren't trued, wouldn't it be possible to "bed" the bottom metal? I was thinking of doing it myself and using a bedding compound for a snug fit.

I would think as long as the bottom metal can be held flush with the bottom of the stock and the holes line up straight, then yes.

Man that is just punishing using a dremel tool....
I did my PTG stealth bottom metal on a manual milling machine and it was not bad. There was a fair amount or material to cut away and it would be pretty hard to make the pillar height parallel using a dremel tool. I have seen guys do amazing things with hand tools but I prefer a DRO or better yet a G code machine.
 
with the right bit, it wasn't bad. but again, nothing is trued, will probably use a little bedding stuff to "sure it up" as much as i can very soon.

the dremel bit i used looked like a small router or milling bit, of course it was one of the last ones i tried, made short work. the good thing was the back of the well meets a part of the receiver which will stop it from going too high, in the front it bumps against the feed ramp. plus looking at how much the mounting screws engage the receiver was a good indicator of how deep to remove materials.

i went a little too far in the back pillar, had to actually shim it with a washer between the pillar and BM to reduce what i would think is flex or uneven torque.

again, after paying for the BM and mag and special dremel bit plus the time spent, i should have just sent it out and know that everything was squared / flush. seen no accuraccy issues, BUT i can see how easily you can F things up, and don't know how much, if any, accuracy would have been improved by having things trued.

bottom line - bottom metal inletting - even if your handy and cheap like me, send it out.

sorry to go a little off topic, but just a tip, if you went as far as getting a decent stock, BM, etc, don't skimp on the install. it's not brain surgery or hard to do, but if one is building something right, DIY with a dremel / drill / other is kinda silly just to save another 100.00ish.
 
Just to point out though, in case the OP isn't aware, you guys talking about Inletting for the PTG bottom metal used the stealth unit. The OP has a long action, therefore PTG has readily available units that drop in to a bdl inlet
 
Other than a couple of AICS, I only have experience with three dbm from CDI and the BO on a mini chassis from Manners. I find the BO a little too tight for quick mag insertion compared to the CDI. Both do drop empty mags on command, but personally, I like the easier mag insertion of the slightly looser CDI. I know this is limited experience, but it's all I have.
 
The Badger M5 is the way to go if you can afford it and have a stock with the proper inlet made.

If you are on a budget and want to keep your BDL stock, then use the Wyatt bottom metal.
