Way cool pinhead. Keep us posted on this set up. What are your plans for the barrel?
- Thread starter patches
- Start date
This is just an idea at this point. I’m sure there will be several people that will chime in and say the SRS chassis accepts a 1.25” barrel and the 375 CT requires a 1.4” or whatever diameter the HTI’s use. Or did DT have to design the HTI for the 50 cal, and the 375 could work with a 1.25” barrel diameter? I haven’t spoken with anyone who would know yet, because this is in the idea stage.
416 rigby and 505 Gibbs are a lot similar then a 50 bmg or the 416 barrett. Pinhead is on to something here. I mean to say is the lapua case is not too much smaller than the cheytac vs a lapua case to a 50bmg.
I don't know if DT Had to design for the use of the larger barrel but I can tell you that there won't be much room in the 1.25" barrel for a 50 BMG chamber. I don't think I'd want the 375 CT in the smaller dia barrel either. Its not a lot more powerful than the 338 LM but its enough. The case is also enough longer that it won't fit in the magazine so you're limited there too. I think they designed the HTI to be a larger version of the SRS because its a good design but it needed to be bigger all around for the larger and more powerful cartridges. The whole thing needed more weight too for the recoil of the larger rounds.

I have had a DT covert for a couple of years now but only have one barrel. I have been considering several things but was curious what everyone's experience has been with Ackley Improved cartridges. Very little body taper and sharp shoulders... Do they feed alright or does that create problems with this platform?
ive heard of people running 338lm AI in the DT with no issues ,
i would put it down to Certain Cartridges will run better then the other .
i know Orkan has a few wildcats he should chime in
Wanted to give a big shout out to Greg, Josh and Chris over at Primal Rights as well as Travis at TS Customs for helping me put together my 1st DT. After 2 years of off and on phone calls with Greg I finally made the plunge. Had to sell 2 custom rifles and an extra scope to make this dream a reality.
This will be my go to hunting and match rifle hopefully for a long time!
Specs:
SRS A1 Chassis - Full Cerakote job
Chambered in 7 LRM, 22", 1-8 twist, spiral fluted, timed TBAC Brake
34mm Hawkins Scope rings
Tangent Theta 5-25 Gen 2XR
I just picked it up late last Thursday, and on inspection, it has beat all my expectations. Spent most of the day Saturday prepping brass, finding lands and loading for powder test. Planning to build loads for both 180 Berger Hybrids and 195 Berger EOL's.
I did mange to send 5 rounds in the back yard at 80 yards just to get the scope on paper. Very impressed with how soft the 7 LRM recoil is. I cannot wait to get it to the range in the next couple of weeks.
I cannot say enough on how Greg and his team went the extra mile for me, he earned my business through his willingness to listen to my needs, telling me truth (not just what he thinks I wanted to hear) and sharing his knowledge.
Thanks guys to a job well done.
I post up some groups soon as I have load built.

Welcome! Nice paint job!
Respectfully, no one is talking about putting a 50 BMG in an SRS. I was simply stating from a ground-up design aspect, the SRS was designed around the 338 Lapua Mag, and all other "lesser" calibers should work just fine.
I assumed the HTI was designed around the .50 Cal, and again, all lesser calibers would work.
However, my main question was about whether or not a 375 Cheytac would work in a 1.25" diameter chamber that the SRS uses. I haven't talked to anyone seriously about this, just throwing out an idea. I think the feedback so far and looking around on the web is that its marginal, so with the bullpup configuration, having something marginal right next to your face may not be the greatest idea.
Also, this would be a single feed; the 375 CT case is too long to fit in the 338 LM magazine.
I think it would be worth trying to ask David Tubb what diameter barrel he runs in his rifle platform.
Does anyone have an HTI barrel and can measure the tenon diameter? 1.4? 1.6? Again, I assume the tenon diameter was designed for the 50, and the 375 CT may not require the same. Just like the 338 LM works with a 1.25" in the SRS, but a 260 Remington can use a 1.15" or 1.2" in a standard rifle.
I've got a 375 CT HTI barrel down in the shop so I can measure the diameters of the barrel and chamber and post later tonight.
Pinhead,
I didn't think you were trying to put a 50 cal in the SRS size platform, just pointing out that there wouldn't be room. Sorry if I made it sound like I was making fun. Not intended that way. I'll get some measurements posted and we can see if the 375 is too big too.

OK, here is the info on the HTI 375 CT barrel. The breech end of the extension is 1.615" in diameter and the chamber opening is .640" diameter.

Thanks Frank. I appreciate you taking the time to do that.
How did the testing turn out?
We really need a Desert tech sub forum on here. Too many good topics get lost in this mega thread.

Has anyone got the bolt coated to smooth up the action?
I've run mine about 500 rounds at this point, with a little lube on the bolt and a bit of grease on the lugs, it seems very smooth - not AI/custom smooth but very smooth. I've heard that the micro slick will do wonders for the smoothness but I haven't tried one or seen the need for it yet. There is also another bolt coating - eludes me at the moment - that is supposed to be the cat's meow. Something new everyday. I suppose I look at the DT as an ultra functional and rock solid platform much like a Glock. Not the smoothest or prettiest but completely acceptable, hyper accurate and reliable.
I've run a few thousand rounds through my SRS over the years and the bolt is really smooth. I use a little grease or oil depending on the season and it helps a bit. I've never been all that concerned about it as long as it works and didn't take too much power to close. So depending on how smooth you think it really needs to be you can grease and wear it in or go to some custom superslick coatings that cost a lot and may not be any better?

The SRS has been in the back of my mind for at least four years. I still may revisit the idea of owning one some day. Problem is Orkin introduced me to the world of TT. Saving up for my second one. The TT on top of a DT SRS would be a serious combo.
Good god that is freaking nice

Painless300 , sweet rig there.
Thanks guys. It’s killing me not getting to the range yet! Hopefully I’ll get some rounds down range next weekend, having to work just sucks.
Painless300 , if you decide you need a spare SAC fluted 7 LRM barrel and a pile of brass let me know, I'm going to be going in a different direction soon .
Beautiful rifle by the way .

I am in need of a standard magnum bolt - .540 bolt face for 300 WM, etc. Anyone want to trade your .540 for my standard bolt - .470? I will cover all shipping.
I've got 5 6.5 Creedmoor barrels that I used for testing that I am selling. They are made from Criterion blanks. Each barrel has about 25 rounds through it and all shot approx. .5 MOA using 147gr Factory Hornady ammo. 8 twist.
1 - 25 inch
2 - 24 inch
2 - 22.5 inch

Are you testing any 24” 300 Norma barrels in the future?
Finally! So comfortable. And now that they have the template you guys are welcome lol I sent them my cheek piece so and they did one hell of a job. Shoutout to Wiebad!

Did you happen to get velocities out of the 22.5” with the 147s?
Fantastic, thank you! I’ll be putting in an order for one of those. Looks great!
No, we were just testing the blanks for accuracy. Other barrels in that length have been mid 2600s.
Let me know if you're done with that fore end you did. It looks sweet.
OK, thank you for the reply!. I'll be in the market for a 22.5" here in a few months and I plan on giving you guys a call for the order.
Did you request a SRS version? Not seeing that option on their site.
Yea you have to call. Mine was the first they’ve ever done so I had to send my cheek piece in. But they should still have the template for it.
I'm done with the metal work on the hand guard , but it's not going anywhere. I need to get it coated and it'll be complete .
There seems to be several members interested in the mods I've done to my hand guard , if anyone wants theirs modified I'd be happy to do it .
I'm going 300 Norma, any issues I should be aware of?
Only issue I can see is finding components. Not sure of brass availablity right now. Have at it and have fun. Neat round.

I bought 250 brass yesterday, got that covered .
Does anyone know if the DTA SRS A1 Monopod upgrade kit (found on eurooptic and eBay) work with a Gen 1 SRS? Looking to get the monopod and Buttpad of SRS A1 without buying another chassis.
