Nukes, You need to put a little space between you and those reactors.
Space,..... time, AND shielding [laughing].
But seriously, isn't anyone else tempted to lock a .26 Nosler into their DTA?

...Although with the ease of barrel swaps on the DTA perhaps someone will come out with a bulk deal, where you can buy a 10-pack of 26 Nosler barrels on the cheap.

Hey Nukes you are more than welcome to come shoot my DTA 6.5 SAUM barrel any time, we appear to be in the same neck of the woods. The barrel life gained is worth the 100fps lost!
has anyone used or use those adjustable scope base's? on these dta rifle systems.

How does it feed? What % And which mag do you use? 2.950" OAL from the 308 mag is limiting I would say and case length being that short for the long mag... Well that's another issue.
If you are running an HTI 375CT, HEADS UP!
I've been working with a customer that has an HTI in 375CT. He has been having sizing issues. His Jamison brass was working fine, but bertram brass was becoming deformed. I finally got an opportunity to get over to his house to see what was happening.
Notice the massive crimp in the total FL-sized piece. That is with the die setup so that full contact with the shell-holder is made. The one on the right was with the die adjusted so that there was no contact with the shoulder and only sized the neck. As soon as any shoulder contact was made, the crease began showing up.
The customer purchased their 375CT dies from CheytacUSA.
It is very clear that Cheytac is using an entirely different chamber reamer than Desert Tech is using in their HTI's. Completely different dimensions in the shoulder area. The HTI chamber is more modern in appearance with it's defined shoulder and precise shoulder/neck/body junctions. Clearly, any attempt to resize HTI once-fired brass with a CheytacUSA die will be met with undesirable results. Not having a SAAMI spec for 375CT is clearly not good for the cartridge.
In short, do not buy your dies from CheytacUSA and expect them to work with your HTI.
SOLUTION:
Buy some DTM factory ammo.
Fire it in your HTI.
Order 375CT die set from Whidden Gunworks.
Arrange to have the die custom made, and send in 5 pieces of 375CT brass which has been fired in your HTI.
What's that saying...? You can be the pillar of the community, doing nothing but good for 60 years... but you molest one child and...
That post wasn't meant to ostracize Cheytac. It was meant to educate people that clearly Cheytac uses a different chamber than DTA, and thus their dies are not suitable for the "rest" of us.
Do you know if Dave uses dies mated for Cheytac's chamber, or the PTG chamber used in the HTI's?
It feeds about 90% out of the 300 win mag, but it is only the first round that gets hung up. I wanna give the .308 mag a shot, next. I am fine with 90%. It gives me something to blame my slow shots on
Its so much fun!I can tell that I have the same sickness that you all have. The endless possibilities of cartridges that the SRS offers.
We have done 2 6.5 SAUM barrels for the DTA so far. Goatsie, and propulsionclimbing. I know that propulsion is running 308 magazines with the feed lips slightly bent. He claims excellent feeding. I am going to ask him to post up some pictures of his mag, and am curious if he can still run 308 out of the same mag. I have been meaning to turn one for myself, but am currently side tracked with 6 Creedmoor. More to follow on that.
Nukes, I'd be happy to turn a .26 Nosler for you, and have a 6.5 blank in stock. We would just have to wait on the reamer. I really don't know anything about it, so you would have to pioneer the magazine set up, but it might be fun and as with your 6.5 Creedmoor I'll be happy to help you find a load.
Also, I have a new 7 SAUM barrel that I can't get rid of. I understand the concern is feeding, and posted a video of it feeding. However, I no longer care and just want to get rid of it. Any reasonable offers will be considered.

Ty
Fireguyty asked me to post up a pic of a 308 mag modified to feed the 6.5 SAUM (or any SAUM family cartridge for that matter). All I did was take some pliers and proceeded to bend the feed lips until I got the cartridge sitting high enough out of the mag to be caught by the bolt and with a slight upward slant. After I did the bending, I took some fine grit sandpaper and buffed out any scratches or burrs. It is a super simple modification, and I can tell you it feeds 100%. My only initial reservation with the 6.5 SAUM in a DTA was the potential for feeding issues. My concerns were unfounded, and the results I have achieved with the 6.5 SAUM Ty spun up for me prompted me to sell off the 260 Rem conversion which I initially anticipated would be my go to barrel conversion.
Bottom line is that with a slight modification to the 308 mags, the 6.5 SAUM feeds like a dream as in 100% of the time. I can't feel any difference between feeding 6.5 SAUM cartridges vs. feeding 308, 260 or any of the conventional short action cartridges.
As a caveat, I would not recommend using a 6.5 SAUM in the 300 Win Mag or 338 Lapua magazines. I have been down that road before, and the length of the feed lips is not sufficient. The cartridge pops up out of the feed lips before the bullet tip gets into the chamber opening thus causing a major hang up. You can avoid this occurrence most of the time by making a very smooth, even bolt push; however, I was never happy with the results. If you must run a 6.5 SAUM in a long magazine, the only way to achieve excellent feeding would be to remove the spacer from a 308 mag by dremeling out the spot welds and swapping out the 308 internals with long action internals. The feed lips are longer on the 308 mags which avoids the problem of the case popping out of the feed lips prematurely. I did this with good results for a 284 Win. conversion I had.
However, this is all not necessary with the 6.5 SAUM. The current reamer most people are using (including the one Ty has) was designed to be run in a short action with a COAL of 2.880" when running the 130 Berger VLD and 2.905" when running the Berger 140 Hybrid. I have had superb results with both of these bullets along with H1000. A 62.5 grain charge of H1000 propels the 130 VLD to 3225 fps MV (as measured from a Magnetospeed V2 chrony), and a 60.5 grain load of H1000 propels a 140 Hybrid to 3084 fps MV. Both bullets have the same POI at 100 meters, and are easily 1/4 MOA accurate. I have shot both loads out to 1700 yards with excellent results. The 6.5 SAUM is the real deal and works exceptionally well in the DTA with very few modifications.
I have owned rifles with the very best components from the very best gun builders available including multiple custom DTA conversions from all the usual sources, and the 6.5 SAUM barrel that Fireguyty spun up for me shoots as good or better than them all. I would look to Fireguyty for all of your DTA conversion needs. He will treat you right and provides a superb product.
As an aside, you can see from the pics that my bending skills could be improved upon. But the mags work perfectly!
Nice Jed, what are the spec's on that barrel?

So after modding this mag, does .308 or .260 cartridges still feed fine out of the same magazine?
TheBelgian I was finally able to install my Kahles K624i DT-AMR (thanks Greg!) in the DTA mount (40 MOA) on my SRS-A1 and thought I'd post some pics of it. Fireguyty was right... it's worth the wait and that AMR reticle is ridiculously sharp and granular! I really love that it gives .05 mil increment!! I haven't got the chance to actually zero the scope yet as it was stormy today but I'll make sure to post more pics once I do!![/QUOTE said:looks clean, hay let me know what you zero it at with that 40moa base.
looks clean, hay let me know what you zero it at with that 40moa base.
Thanks, that was the sanity check I'm looking for as that's pretty much inline with my expectations and QL prediction.
I'm nearly 2 grains higher and 150fps slower in Lapua brass at a COAL of 2.85" with temp at 45F.
Lots of variables there I know but a long way from what appears to be the norm.
I'll look in to temp variation on rl17 and cross check H2O capacity.
Accuracy is very poor at lower velocities.
There is something odd here.
