I asked this question before, but then it kind of got lost when two other members got into a p*ssing match with each other. So I'll try asking again. I have a LH DTA Covert that I bought slightly used in 300 WM. Just starting to get used to the rifle. The one problem I have is that the rifle is not ejecting a fired round when I open the bolt. To be clear, the bolt has no problem extracting the round from the chamber, but I have to rotate the rifle 90 degrees to get the spent round fall out. This happens regardless of whether I open the bolt slowly or quickly. Am I doing something wrong? Is there a quick fix?
There are two answers to this. First, pull back the bokt more aggressivley and the case will make it out.
Secondly, Mark at Short Action Customs makes a bolt head with a mucho better extractor which I am using on my .223 conversion. Case comes out no matter how slowly you cycle the bolt. I emailed him just yesterday to see if he would make me a bolt head with his improved extractor. I'm hoping he can do it for me.

I'm developing an expanding 200gr. Maker REX Subsonic load for the DTS 16" .308 barrel with Josh at copper creek. I have 10 trial loads in hand, 5 of each and I plan on shooting over my magneto speed for Velocity and SD. Ill also post bullseye cam photos with spread evaluation at 100 yards.
Let me know if anyone is interested in my results.

I know a lot of people complain about the ejection of the cases, has anyone tried to upgrade the spring? Just a thought, I may take apart one of my bolts and see if there is room for a stiffer spring without the coils binding when chambering the round

I need a sanity check guys .

In my never ending quest for more performance and less weight, I'm thinking of having my 26" 300 WM barrel cut to 24", fluted and rechambered to 300 Norma. My theory is the 24" Norma will out perform the 26" WM , while the shorter length and fluting will obviously shave some weight.

Before everyone says to get a new barrel, this one is ridiculously accurate and I'm a cheap bastard , a new barrel is not in the cards at this point.
Last thing I haven't seen mentioned is that the chamber will have to be moved forward shortening the portion of the barrel that the receiver locks onto. Not a good idea. The only real problem I see with the DT type barrels is that you can't reasonably set them back. If they were made with longer 1.25" dia shanks and simply notched for the lock it might be a different story....as it is your front pinch bolt will have nothing to pinch and I wonder if accuracy will suffer from that?
As someone else noted, get rid of the 300WM and get the barrel you want.

I am getting out of the DTA game. I sold off my rifle but have a 6.5x47 barrel and a standard bolt head left. I figured somebody in this thread could use one or both of them. They are posted in the accessories section of the classifieds. Thanks

I asked Mark at SAC, he doesn't make them.
I might bring my head to a local guy and see what happens.

I'm getting 1,020 fps from his hottest load which is double black on the picture above. ( far right)
I bet the double purple would work good for you which shot about 950 out of my barrel. Talk to Josh there. He is the guy who just did this developing for me.

Also, those REX projectiles are incredibly accurate and the are devastating.

What grain bullets and what charge are you using? Where do I find Josh?

has anyone had success using the zero offset in ballistic calcs to track poi shift between barrels? or just writing down zeroes and addind or subtracting from your dope?

Do it all the time. My 6.5 creed is 1.2 up and .4 right from my zero. My .223 is 1.5 up and .4 right. Easy calculations. I used to write them down and do the math in my head, but once I figured out how to do it in StrelokPro then I did it that way. Much easier when shooting on the clock.

That’s the kind of input I was looking for
Thank you

Saw this video on YouTube and saw a very interesting rifle in the first 30 or so seconds ;) does this mean a military is using one?


Curious minds would like to know!
I’m aware that certain groups can use whatever they want more or less, but even if it’s the case of just one team that would still be awesome.
If anyone has any insight into this please let me know!

200 grain. Maker REX.
Copper Creek 573-321-4210 he usually answers the phone. If you mention Maker REX expandables he will know which loads you are referring to, we just ordered 100 rounds and its the first time he developed that projectile. He used trailboss and a mahnum primer which is a fast and they did a great job. Pricey, but I'm ok with it as I only reach for that load when I need perfection.

Other than upside-down, I've never really understood how a flag can be facing a "wrong" direction, considering you can view a flying flag from any angle in the wild. It seemed appropriate since it's facing the other direction on the opposite side of the mag.
Anyway... no, with the classic Duracoat, it's a 2-part epoxy that air dries.

Check DT's website. Several countries are using them.

Been kinda slow hear. Looking good supressyourself. I like the paint job. Went shooting today at my friends farm. Couple steel plates and 12oz cans at 400yd. That was fun. If you hit it you had to walk down range and change out for a new one. Got some exercise in today.

So I’ve just started using my 338dtss , and I was using my silencer co hybrid and it seems like the dt muffler doesn’t get as hot as the other suppressors . You guys with desert techs cans , do you notice that or is it just me?

Currently, I have 3 conversions and they all shoot great. Two are from SAC and one is a TS Customs. The SAC 223 conversion is especially accurate and will hold 1/4 moa or better with best 5 shot groups in the .1s and an occasional 4 shot group in the .0s at 100 yds. The other two are nearly as good, one being a 260 Rem and the other a 6 Creedmoor.
I finally broke down and ordered a 308 since I have never owned one in the 46 years I've been shooting, believe it or not. I decided to try out a factory barrel in 22" to see how I like it and how it compares to custom conversions for accuracy. All my other conversions are 26", so I wanted to have something a little lighter and more compact. I hope it shoots as well as my customs.
Well, got out today with my new factory 22" 308. Loaded up some Sierra 175s with 42.5gr of RL15. Took one shot to zero the barrel then shot this group...

Zero load development. The factory barrels hang right with my customs for accuracy. Very pleased!

I have even thought about adding the old brush style protectors cars had on the gear shift. Add that to my action to reduce the amount of dust that enters my action. That might help with the bolt smoothness.

Here's a bad pic of what I'm referring to

Dude! I think you're on to something! Dunno how it could be attached though, would have to take apart the chassis to make it look good.

Hi everyone, went to the range the other day and forgot the short throw/stop plug for the DTA in my safe and tho its not a mission ending issue it pissed me off so I designed a replacement, printed out a few and now have one in each of my range bags, case and gun bag so I will always have a spare. no special print settings hear just use what ever your printer likes. The original seems to be made of a better plastic than the PLA I used but figure its not meant as a permanent replacement but more a temp solution. Anyways hope it can help someone out.

I had that happen years ago, so I just forgot about it and shot without it, haven't looked back since.

What are you guys using for a sling ? I don't know shit about flush cups but assume that's what I'm going to need in a sling ? Rifle will be strapped to my pack most of the time while hunting, but I want the option of carrying it with a sling when needed .
