Oh and for comparison, with an 18" .338LM it's really hard to get 300gr bullets going faster than 2500fps from my experience. Even with a monster brake, that short .338LM is not pleasant to shoot for long, but I suppose if you're hunting then that's not a problem? A can would make it less of a TBI generator, but you'd want to make sure it was rated for such a short barrel.

18" 338 shooting 230-250s with or w/o a can using "faster" powders like H4831 or H4350 may be interesting
Are you running strictly factory ammo for those 415s or have you developed your own load?
It averaged 1 1/4" groups. I haven't tried the 408 or 416 with the custom abr bag rider and custom protektor rear bag yet. I feel quite sure both will be below an inch, especially if these 2 calibers react like the 375 and 50 did.
I added a UTG Over Bore Bipod to my SRS A1 .338LM and I also bought 2 new mags. Now I'll save up so I can load the mags and finally shoot this beast.
What distances do you all recommend for zeroing? I've never shot .338LM and I am very excited.
That will start to fade when the costs start to add up.
I love my .338's but they are expensive to feed.
Reload 285-ELDM for about $2.00 a pop
Lapua brass will get 10-20 reloads so about $.20 a shot, 90ish grains of powder about $0.75 and then $1.00 for projectile and $0.10 for primer
Cheaper than fed GMMM 223 ammo

What reticle are you running in that optic? I’m thinking about ordering one with a T3 and waiting the excessive amount of time for itSpeaking of 285 ELDM....

I need to at least swap my current 3-20x onto my DT, the krypton isn't the biggest fan of the 5-25x
Much less of an issue than with the 5-25x, test fitting the thermal with the 3-20x
Hey guys, need some pro advice. I just got a new barrel for the SRS A1. Breaking it in and cleaning every round as usual.
Little hiccup. It’s blowing primers out with factory Hornady ammo. And I mean BLOWING them out.
Massive cratering and piercing. Some primers were stuck in the bolt, some would fly out when spent shell was ejected, I think 1 got obliterated.
I shot 1 round suppressed and it seemed fine. Started the cleaning process and didn’t want to fiddle with the suppressor every round, so I shot 5 unsupressed.
Those are the 5 that were blowing like crazy and had massive bolt lift etc.
Any ideas on this? Any insight you may have is much appreciated.
Ive never had a barrel do this before with factory ammo. Barrel was cut with a Manson reamer. I contacted the barrel maker and asked for more detailed specs. Waiting on a response. Here are 2 fired brass. I need some help trying to resolve this.
Thanks

Are you leaving solvent in the chamber after you clean? It’s an easy thing to do and could be causing the pressure spikes, especially if the first round was good.
Does anyone know of any current options for finding a longer handguard and/or long arca rail for a SRS A1 Covert? Seems like the A1 stuff isn't made anymore, understandably.
Has anyone had any luck with trigger mods to the newer A2/M2 trigger to get rid of creep and lower the weight a bit? My M2 has an inconsistent amount of creep. It's always there, sometimes a little, sometimes a lot. Once it finally gets through the creep it breaks crisp. I feel like this trigger has a lot of potential to be great but It shits me to tears that they removed the adjustments from the A1 trigger. That trigger was excellent and certainly better than the A2 trigger. I really wish they were backwards compatible, I would just swap them.
Scroll up for several pages to my numerous posts on the topic. I got mine down to 16 ounces with zero creep.
How did you get the weight so low? I posted about the creep fix a while back but no creep doesn’t equate to a low trigger pull weight. My trigger won’t even go down to 2.5 lbs. I’ve tried to contact DT many times and finally got a response saying that someone will be reaching out. That was about three months ago at least. I despise this damn company.
I've had good results with the 285 eldms in my 338NM on sambar.Speaking of 285 ELDM....

they shoot well too
Finally snagged a SAC 223 kit with a 26” 7.7 twist Bartlien for my M2. Should show up next week, can’t wait to have a 223 in the rotation again.
The details on exactly what I did are seven pages up. You can just scroll through approximately February and just look for the pictures.
Yeah, that doesn’t work at all in my example. The set screw can be completely removed and I can’t get down to even 2.5lbs. I’m sure it’s because of DT complete lack of quality control I’m sure. I’d be happy if it made it down to 2 lbs which is already higher than Desert Tech’s own listed spec of 1.5 lbs.
I bought it (very lightly) used, few hundred rounds on it. I’m up in Canada and ordering a new kit from SAC is a pain in a** and there’s one distributor who sells them up here and they price them quite high. And they only offer 18-22” barrels, wanted a longer one.
Took some patience to wait for the right used kit but it paid off because I got it at a great price.
Hello all - looking for some input on a 338 norma barrel. With length & weight not being of great concern (within reason) This will just be for steel & turning rocks to gravel at extended ranges as my ability grows. Would it be worth having a faster twist (9....) to accommodate future bullet designs? How about length - worth doing say 30" to get the extra velocity without having to push components as hard and still take advantage of the round? Probably overthinking or would the factory DT 26" 10 twist do just fine for the majority of what's available? Been collecting components and figure I'll start with the norma brass H-1000 and 285 eld-m. Thanks for the input 
Don't reinvent the wheel. The 338 Norma is just like the PRC cartridges, designed to give a shorter fatter case to allow long heavy bullets to be shot when mag length is limited. There is NO MAG LENGTH LIMITATION with DT SRS. So there is NO POINT in 338 Norma in an SRS
Get a 338 LM barrel, 26-34 inches, about 1:9 twist, shoot Lapua brass, 285 ELD-M and Retumbo (not H1000).
I would not sacrifice performance and track record of 338 LM for a 338 NM, and use Norma brass when Lapua brass is available.
There are a ton of successful 338 barrels on this thread dating back over a decade. 338 Norma fills a void that does not exist in an SRS; it is a solution to a non-problem. So....think hard about it.
