Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

Is there anyone in central Arkansas that would let me get a feel for this rifle before I buy one. Don't really have to shoot it but
would like tho get a feel for the ergonomics. Thanks

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

When did DTA say they would not be offering the PSR? They didn't get selected after answering the RFP. Didn't the PSR get canceled anyways? I think that DTA made a lot of improvements on the original rifle for the PSR.

better buttpad
better rail design
better grip for the mono pod
cheek piece
20 MOA rail
2 pounds lighter
dust cover

Some of those things need to be brought over to the civilian rifles.

Nick also said that he will probably be offering a retro kit that will essentially make your existing rifle a "PSR"ish system. Time will tell.

I already have my build underway. The shoulder is improved 40 degree and neck blown out to 375. I haven't looked at the mag as yet if it will accept it. Here is a 338LM on the left and a 375 on the right after hydro forming and neck expanding.

Mine is being built by SAC.

 

[biffj]

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

It looks like the fit in the mag will be a bit tight on the shoulder. Not much room in the mags for movement forward of the shoulder. May work though....just have to see.
How are you hydro forming the brass? Using hydraulic pressure in the die rather than simply fireforming the shoulder and neck???
Good idea but I just wish the bullet selection in 375 was better.

[Dogtown]

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

I agree that the magazine design's shoulder support may give you problems, but it's an interesting development. What kind of velocities are you expecting to get? It seems like the best performing velocities for .375 bullets is > 3000fps- I would imagine an improved .338LM case would be hard pressed to get near those velocities?

 

[Tactical_Tom]

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

I am guessing that the PSR upgrade will just be a new cheek piece / rear grip upgrade.

No monolithic top rail etc. I cannot say that I find the new switchable bolt head very attractive but I like the other features. I guess we will know more at SHOT show 2014....

 

[archaos]

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

The 260gr Accubond with 106.5gr of AR2213SC is pushing 3175fps
The 325 and 330gr CNC VLD's are getting around 2945fps

These velocities are measured at the muzzle from Wello in his rifle that has a 28" 1-10 Krieger, my build is still on the way from SAC and it a 28" 1-10 Bartlien so I don't see the velocities changing that much.

I plan on running around 103gr with my 260gr Accubonds as his loads are right up on max.

The hydro forming is done using one of Hornadys custom hydro forming dies, took about two months to get made from my chamber drawings.

 

[biffj]

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

Thanks for the info and especially the pic of the forming die. I've often wondered if that would be a better way of forming brass than using bullseye and cream of wheat. It appears to work well. I'd thought about bumping the 338 to 358 or 375 too but bullet selection has been an issue. Looks like the 375 may be coming along though due to all the interest in the cheytac and others.
Thanks again for the pics and info.

Sierra has a new 350gr .375 out now to. It makes the cheytac more attractive than it was.

I think that was a PSR requirement as the other manufacturers have gone that route in making their rifles multi-caliber (Barrett, AI, etc).

Switchable bolt head was to improve manufacturability.

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

Someone really needs to run with the 375-338 LM cartridge. It just makes sense from a parent case/expansion ratio standpoint. you really take a step-up on the efficiency curve.

It's just like the 9.3x64Bren. that damn near equals the 375 H&H with much less powder or the "little" 375JDJ (375-444imp)that drives a 260gr BT @ just under 2000 from a 12.5 inch Contender. Maximum neck diameter versus parent case diameter while maintaining adequate shoulder equals smaller, lighter, less recoiling efficient package.

Someone run with it, OK. Hell, call it the 375DTA!

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

I am loving my DTA more and more every time I shoot it.

My most recent load for the .260 conversion that I am running had a standard deviation of 5 fps and today had an ES of 13 fps.

I had a few quarter MOA groups yesterday at 100 yards off a bipod and monopod with the suppressor mounted.

Today, I turned in a 2.2" 5 shot group at 500 yards with some descent wind. That was shot in the prone position, with the suppressor, utilizing an atlas bipod and the factory monopod.

Since I started using the DTA, I have rarely used my other high power bolt rifles.

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

Finally got out today with the new SAC 7SAUM barrel(24"-8.5), just starting some initial load testing to get a good load started. I have to say WOW, this thing is gonna be fun. I shot three different loads for the 162 Amax, the rifle showed a preference for 4831sc and h414. Both loads were around 2975 and were very consistent (2979,2977,2973,2975,ect.) Even though I had no time for brass culling, brass prep, wrong seating depth (they were jammed good) as well as a gusty 15-20mph wind all day, I managed to shoot some pretty good sub moa 5 shot groups. I was surprised cause I could barely hold still in the wind.

I was surprised at the recoil, felt just like my 16" covert .308 barrel, quiet through the can, and very consistent.

I'll be working on a full range report and write up as soon as time permits. This 7 was a great idea!!!!

That was exactly my experience - within a year of getting my SRS I offloaded my .408 Windrunner and .308 SR-90. It really is one of those all-in-one rifles.

Will do. Since purchasing a new (read 60 year old home but new to me), I have been putting most of my free time into fixing up the home. I was glad to make it out for a few hours on Friday and to the PC Comp on Saturday last week.

Let me know how the 7 SAUM feeds from the standard DTA mags.

I have already placed the order for the 6.5 Creedmoor barrels. However, there are two barrels left. I have had a few people inquire recently about the barrels, but no one has sent money in to claim either of the remaining barrels.

[fireguyty]

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

Kent,
Thanks for the answer, using the 338 LM mags? I just worry about them working their way rearward.

Coldbore,
JFComfort, and D.Miller do excellent lathe work. D.Miller has a 7 SAUM in a Rem 700 Long Action that they made. Neither of those guys have a DTA, but have made me a 6.5 Creedmoor and a couple 6XCs for some other friends.

For my own, I am considering a long (32" maybe?) with a twist fast enough for the anticipated 195 Berger hybrid. Seems like that would trump a 338 Lapua in the ELR game.

Thanks for the info both of you,
Ty

No DTA here. I'm a big fan, especially once I got to actually shoot one and see how everything works. By the way thank you for that Ty!

I will get one someday but right now isn't the time. I ditched my 7mm SAUM build and got distracted. Dane and I built his 7mm SAUM on a Rem long action. We have been testing the cartridge for a bit now with 180 Berger Hybrids. It's a really sweet round with impressive ballistics. I prefer it over the 7WSM because of the longer neck.

Keep us updated what you think about the cartridge coldboremiracle! We had good results with H4831sc.

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

Ok, so the magazine issue may take some work. I have two .308 mags and two magnum mags, from what I can tell it looks like Im gonna need something in between. The .308 mags are too short with the spacer in the rear, and the magnum mags lips dont come far forward enough. If I work the bolt just right, they feed from the magnum mags but not reliably enough for my taste. Also the magnum mags will need a spacer similar to the .308, but not quite as long. I think the easiest way to make it work would be to get a half finished .308 mag from dta, before the spacer is welded in, adjust and cut the lips, and put the spacer in farther back. This may take a bit

Anyone have any primers cratering that shouldn't be?

I have a Covert (just over 400 rounds fired) and it craters EVERYTHING fired in it like a factory Rem 700 SPS. By everything I mean Black Hills, FGMM, 175 smk Handloads at 2300 fps (16 barrel), 175 smk handloads at 2450 (16 barrel), and subsonic handloads.

CCI standards, Federal match, and win primers have been tried with no change.

No pressure signs. Primers are rounded on edge, no heavy bolt etc.

Possible issue with the firing pin or firing pin hole I'm thinking.

This was a common issue due to what many cite as an oversize firing pin hole. Somewhere in this string of posts, the issue was brought up. It is speculated that due to the floating firing pin design, the hole was left large to prevent the firing pin from sticking due to fouling. John Beanland mentioned bushing the firing pin hole to solve the problem. I contacted him about it, and he said he wasn't interested in bushing another at that time due to the hardness of the bolt. I continued to fire mine without incident. More recently, the question was raised about 6.5x47 and small primers being an issue with the large firing pin hole. DTA responded that they are now bushing all of their bolts, and they would bush older bolts for this application. As I was switching to this caliber, I contacted them. The bushed my bolt free of charge, and the issue went away. Is it really an issue? I am not entirely convinced. Yes, your primers will look funny. If you are pushing the edge of high pressure, it could be. I never had problems, and I push a 175 SMK to 2750 with 44g of Varget out of Win brass.

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

[ney1]

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

longshot1911,
The cratering was not an issue unless you were shooting handloads over max pressure spec which pierced primers more easily than a smaller hole.

 

[RedGoat]

Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread

Just an FYI for everyone. SR90 informed me that the .243 was discontinued because they were only selling around 10 per year. Wonder why it is such an unpopular caliber for the DTA system...

The 243 Win is a laser but burns barrels fast that is why I think it was not popular.

But that's the beauty of the DTA system. Shoot the barrel burner for competitions, and for practice strap on the .308 and your still getting trigger time with the same stock, scope, and trigger. And having to learn to read the wind better since you are handicapping yourself during practice sessions.
