Official (DTA) SRS, HTI, Covert, Hunter Thread

Just a note on our Aussie Desert Tech importer/Distributer..."DELTA TACTICAL" ....."Danny from Delta drove 6hrs ( one way) to deliver Some Desert Tech goodies that i have had on order........we met him at out local gun shop and had a great chat and organised a shoot at my property in the coming weeks .
Danny is a great bloke and his service is VERY much appreciated...

I'm sure for North of $20k worth of gear he's anyone's best mate...

I can't even get a response from deltas.
 
SAC .223 installed. Love that spiral twist. Threw a Area 419 brake on it just because.
I’ll head to the back 40 in a bit and let y’all know how she does.
I’ve been watching SAC for a long time, so I’m excited!

Bugholes as expected.
Bunch of warm bud lights at distance disintegrated...
God I love this rifle platform.

SOOOO Glad i decided to go the SRS A2 route....my Gen 1 SRS had been fantastic, and the A2 is just the icing on the cake !!!

I purchased 4 barrel conversions as well , and the 300WM is the first i have been using...absolutely loving it!!! :)

225 Hornady ELD-M,s with AR2217 is proving spectacular... See pics..( 200 and 475yds)

Today stepped out to 1500yds......perfect no wind..... and a gorgeous day.. Plate is 12" dia . painted rocks range from 6" to 10-12" ...

First shot at the plate went 4" over the top.....made a correction and just a tad low...next 5 shots...ALL on the plate !!!

Small rock....next 2 shots ..impact on top...:)

The SRS is an awesome awesome platform....

I was keen to get the 50bmg , but many talked me out of it due to recoil/muzzle blast...here in Aus Suppressors are no go ... so just the muzzle brake to deal with that !
I think you made a wise choice... I'm in the US / Virginia so I'm suppressed. Also I don't have the terrain to stretch out the .375.. I'm a big fella at 6' 5" 330ish so I just deal with the recoil.. It took me a couple days to decide on the .50 when I bought it.. I think my "So called" friends influenced my decision a bit, just because they wanted to shoot some of my $8.00 Ammo... LOL

And yes, the mag isn't seated correctly..

Here in Aus.."Packet" 50bmg is pushing $19 a shot..

Mind you the 375 Brass cost me approx $9 each !! so by the time you add powder and projectiles.... its getting up there also..

My aim is to take the 375CT out to 3000yds .........our back paddocks allow this so no drama with space to stretch its legs..:)
 
.......our back paddocks allow this so no drama with space to stretch its legs..:)
As an American in NZ, at my first ELR match I was trying to identify the 2000m target with a local spotter and the convo went like this:

"See where the ridgeline is? Follow the tussock down all the way to the left edge of the paddock and you'll see it"

"Follow the what down?"

"The tussock, follow it down to the left edge of the paddock."

"Um...what's a tussock and what's a paddock?"

Sadly, I’d almost be willing to pay 19 bucks a round if i had a place to shoot 3000 yds… I have a spot at 1500 i get to use twice a year..
 
Anyone used the Berger 379gr and 407gr Match Solids in the HTI with its 1 in 10.5 twist?

Took a punt and purchased a large quantity of these as projectiles are VERY scarce here in Aus.

Now I find out the 1 in 10.5 twist "may" not be fast enough??
If you can get me the bullet length (try to go 3 decimal places in inches if you would) and your expected velocity then I can put the numbers into the formula and we can see what side you're on. It might just be not quite 1.5Sg or it might be much worse. If it's only "may not" then probably it's just the Sg is a little low and you'll lose some amount of BC rather than key holing.

379 are 2.225" or 56.68mm @ 2950fps

407 are 2.325 or 59.1mm @ 2850fps
 
379 are 2.225" or 56.68mm @ 2950fps

407 are 2.325 or 59.1mm @ 2850fps
In 29inHg air I get the following using my own calculator:
1.3Sg @ 40F and 60F, 1.4Sg from 80F to 100F, 1.5Sg From 100F to 130F with the 379's.
1.2Sg @ 40F, 1.3Sg from 60F to 90F, 1.4Sg above 90F with the 407's

Using the Berger site's twist rate calculator I get a bit lower Sg at each temperature band. Enough lower to suggest that the 407's might really not like that and anyway would lose almost ~8% of BC. BC loss with the 379's is similar but a tiny bit lower but it's not nearly as low of Sg compared to the 407's. You would probably get decent performance even with the slightly lowered BC on the 379's but the 407's seem like not a good fit to me.

Since they're Berger, you'll want to jot this URL down: https://bergerbullets.com/twist-rate-calculator/

M2 Advice
Stopped by one of the local gun stores today to browse around and when asked if i needed any help i asked if they had any Desert Tech rifles, his reply was maybe let me check around in the back.
He came back out with a box containing a new M2 chassis and the plastic bag with all the misc pieces. The first M2 I've ever seen and I've got an A1 all the bolts and a collection of barrels and sort of keep up with the values but not for the M2 model. He told me this was a special order and the guy that ordered it ran into some money problems.
So what would be considered a good price range for a looks new chassis and are there any reasons to shy away from this model. Thanks
 
The main difference with the M2 is an integrated ARCA rail on the bottom of the handguard and an integrated 40MOA rail on the top. That's basically it. The limitation is that you can't run a short Covert handguard on the M2 the way you can with an A1 or A2.

I paid $4200 for mine, brand new.

Edit: it's a damned expensive chassis, essentially. But importantly: one scope, many rifles.

Thanks for the response and info on the M2. Think I'll give the guy a call and see what kind of deal he's willing to make. I certainly don't need an M2 but then again if the price is right my A1 handguard gets cut down to Covert length.

I paid 4100 for mine. Absolutely love it. Trigger is heavier than I usually use but it's crisp and consistent enough that it doesn't bother me. The built-in ARCA rail on bottom, all the M-LOC you could possibly desire and the 1-piece 20moa canted pic rail on the top plus a flat trigger (meh) is all pretty great, saves on accessories. 24" barrels are about as short as you'll want to go unless running a suppressor that'll fit inside the HG.

Great day today......

First shoot of the HTI 375CT.......I am in love!!!! :love:

Turns out the 379gr Berger Solid VLD, s do in fact shoot...and VERY well. 134.5gr AR2218 and very promising results. Plate in the images is 20
" Dia.......Distance ....1940yds ( to be exact ) 8 shots fired 3 misses and 5 hits!!

I only loaded up 16rds initially for load testing as it works out to be just on AUD $20 a shot!!

The HTI in 375 is an absolute pussy cat to shoot!!

Love it!!

Is your rail 20MOA? I thought mine was too but was pleasantly surprised that the insert in the manual says it's 40MOA.
Yeah, I love it when the paper product propaganda, the website details and the actual thing don't agree. As far as I can tell it should be a 20moa rail but that's based on where my zero ended up putting my elevation turret within it's mechanical range.

I thought it was 30
Apparently so did someone at DT. I think they might have planned it to have 40, tried it with 30 in early pre-production units and eventually saw the error of their ways and backed it down to 20. Just a guess.
 
It’s 30MOA on the product page, 40MOA in my manual. If I have some time this weekend I’ll go do some Trigonometry in my garage, but otherwise maybe @coldboremiracle knows for sure which correct?
The initial M2's were 40 MOA, after reviewing requests, it was changed to 30 which seemed to be more popular. Mine is one of the OG's, still has the 40 on it.

Glad you love it, I had my HTI out this morning doing some 900 yd shots... These rifles are incredible, my .50 BMG hits shot after shot right on top of its self if I allow it too without anticipating the recoil..

Any ever have issues with feeding issues using 10 round short action magazines (.308, 175 gr SMK) and know how to fix them?

I have a SRS M2 and sometimes the gun gets jammed up when trying to chamber a round. When it happens I have to pull down on the magazine in order to get the round to chamber.
 
My Gen 1 has long had an issue with all magazines where there's lots of play with a seated magazine, and in certain situations when the front of the mag drops down slightly, it causes feed issues. I've just gotten in the habit of supporting the mag slightly with my non-firing hand.

You might play with the tension on the bolts around the magwell of the skins.
 
I was keen to get the 50bmg , but many talked me out of it due to recoil/muzzle blast...here in Aus Suppressors are no go ... so just the muzzle brake to deal with that !
Mine has a 41" Lilja barrel, makes one hole groups (see profile pic), puts blast way out in front of me, and has an AR50 brake so recoil is not bothersome. The DT is the perfect platform for a 40" (or longer) barrel to maximize the potential of 50 BMG (which was designed for a 45" barrel).
 
Shot my first PRSish match with an A1 in 6.5 manbun on Saturday. Got called at 6/10 stages due to a storm rolling in.

There’s some disadvantages for sure (try sliding hand down tripod rear support for cattle gate) but it sure was fun to see the silly looks on peoples faces.

Still my second favorite rifle. I really love one of my .22s.

I shoot PRS with mine when I can afford to. Lots of “ where’s the rest of it?” type remarks. Everyone’s a comic till we have to get our rifles in and out of tight spaces.
