300WM MDT Metal Magazine - 5 Round

Review for Tikka owners specifically:

This is one of those products that have excellent build quality and love the team behind it, but the functionality is rough around the edges. For starters, it's the only 300 Winchester Magnum Magazine MDT makes that's compatible with any long action Tikka chassis (for me, it's the Field Stock). Some of the issues I find:

1. It leaves some light marring/marking on the action of the Tikka, which doesn't affect functionality but it's definitely not ideal (I almost went crazy trying to find out what was causing it on my bolt, and I just realized today it was this magazine). It appeared on my bolt after I first swapped out the factory stock for the Field Stock, bothered me enough to go get it fluted and polished, just for it to come back again with use.

1. The stamped metal folds at the bottom of the magazine where the steel is folded together is quite sharp at the edges - I filed them down until they were round so it's more comfortable to carry with the rifle on my back.

2. As another review has stated, this is more of a 3 round magazine if you want easy loading - the last 2 bullets become really difficult to shove in there due to the stiffness of the spring

3. This isn't really a big deal but if you're a reloader who collects your used cases, the feed lips will catch really hard on the first 2 rounds if you load all 5 rounds, which causes deep scratching along the entirety of the spent casing

4. Not necessarily a fault with this magazine, but because MDT (or any other manufacturer) doesn't make a 3.56" AICS polymer magazine for the Tikka 300 WM, if you want a lighter weight hunting mag you're unfortunately out of luck. And this is definitely not a hunting magazine!

Please make a polymer version for the Tikka 3.56" 300 Win Mag! Thank you

Awesome oversized magazine for the 300 WM I have it in. Allows for larger than normal reloading.
Cycles perfectly. No issues to date.

I loved the mags thanks once again!! Awesome quality!

Spring is very stiff and the cartridge guide "fingers" are pretty sharp. So it is a bit challenging to load to capacity and unadvisable to do so. Unmodified this is more like a 3-capacity mag at max; if I load any more into it it gouges material off the case as the cartridge comes out, stiff spring and sharp edges combine to do a number on the brass (tough to photograph, uploading the best pic I got. Not the worst I saw before I started limiting to 3). I need to try filing some sled-runners into the leading edge, see if that fixes it.

The custom virtual meeting was helpful to confirm what I was ordering was what I needed and wanted. Also the product knowledge of the staff was incredible. These guys don't just sell their products they use them, test them and help in the design process. The installation of my action into the chassis was simple and quick. Then once I got it out in the woods and was able to confirm my point of impact was still on and less than .5 MOA.
I'd like to thank MDT again for their sponsorship of The Veteran Hunters and we look forward to getting some of our veteran hunters out on this incredible chassis weapons system.

I bought this magazine for 300wm loaded with 175gr Barnes LRX loaded long in a Tikka T3X. I partnered this with an Atlasworks bottom metal, great combination.
Of note, MDT doesn’t offer a bottom metal, and doesn’t have any Tikka chassis that’ll accept larger mags.

It looks good, But if I would ever get my stock I ordered it for i could try it.

I only give it a 4 because everything is so dang expensive but it sure works good

My metal 300WM 5RND 3.715 feeds reliably and fits perfect in my Rem700 LA Oryx Chassis. Fits my 7mmRemMag rounds perfectly.

It is great

Perfect! Great feel to them and fits snug in the HNT26

As described, perfect fit

Perfect

It feeds very rough but not every time. It feeds better if I run the bolt hard and fast. Slower results it bolt overs. It will not feed the last round at all. This is after instructions from customer service on how to tune the magazine. For the price I believe it should work without having to tune it.

new stiller long bottom metal. new mdt 3. 85 300 wm 5 rd mags do not feed. ammo goes base down when mag inserted. . level the ammo, first round may feed but not the second. . i see nothing in your site actually covering loading the mag and why ammo is staying base down. . . new mags not feeding

This 300WM CIP length magazine fixed my feeding issue in my custom 7 PRC build.

I ordered the 300WM MDT Magazine. I got my order very quickly. I have taken it to the range and it preformed perfectly. No jams or misfeeds.

With a little modification it’s working perfect for my 300 weatherby

I purchased two of MDTs 300 WM for a 7mm PRC. They were recommended by the manufacturer of my chassis build. (Outlier). They are a solid piece of kit. They are silky smooth with my 700 Remington Long action. The magazines are metal, solid construction and they scream quality. The followers do a great job feeding the 7mm PRC rounds. What I really appreciated was the MDT customer service. Originally, I ordered the wrong model. Once I realized my mistake they were very responsive and polite changing my order to the correct model of magazine I needed. I’m am a fan for life and purchased a Bravo Chassis for a different project and probably will purchase more in the future.

300 win mag functions like it should no issues!

Got 5 rounds in each mag to break in
Awesome magazines

300WM MDT Metal Magazine, appear to be high quality, I'm still building my new 7PRC so I haven't cycled the mags yet, but I anticipate no issues the MDT mags are great.

Good product.

Quite nice and fits description.

Mag base falls off all the time. Every time in a match have to look for parts on ground

They fit perfectly.

Great quality as I was expecting from MDT. Very happy with this

Works very well after a bit of a break in period. Great solid magazine for the price.

Just as described, fits perfectly in my chassis.
