Hey thanks for the response & all the great info! 150 rounds of 33 XC in 1 day... ughMakers kit "A" is the one you need. I think reaming your current barrel would be the least expensive route and you have the correct bolt face with your 338LM so nothing else to do. Tubb has the Manson Reamer for $220.00.
I really liked the idea of interchangeable calibers but truth be told, once I have a favorite caliber, the other ones rarely see the light of day. I keep my 338NM Barrel around because I love that round and it mag feeds, but the 33XC is just better for the mile plus shooting I'm enjoying. Recoil is a breeze with the Barrett/33XC combo. In fact, when I trained with Chase, he unloaded the bipod and had a relaxed hold with the buttpad just resting on his shoulder. I said, "So you take the full brundt of the recoil" and he said "yes". Allows the rifle to track much better if you don't use ski's. Now if you've seen Chase, his biceps are as big as my thighs, so I was a little hesitant, but I shot fantastically with that method and even after 150 rounds of 33XC that day, my shoulder felt like it did when it started. The MRAD is absolutely perfect for the XC. I believe I've stated before, Chase said I could take my Barrett with that Bartlein barrel and enter KO2M and place. I told him the only problem with that is I would need him spotting since I still lack the experience to manage the wind at those distances.
One more thing, you could actually use the Maker's kit for the 37XC or 41XC when they are back in stock if your lust for ELR isn't cured with the 33XC.

I misspoke. It was over two days. But still recoil was mild.
Anyone shot a PRS match with one?
yes, it comes with a Pelican case and 1 extra mag, the extra barrels were on back order, and I didn't want to wait, so I bought the Mrad in .338 Lapua, SMR in .308 and SMR 6.5CM. I will probably order the extra barrels, but I am in no hurry anymore. Shitty thing about the SMR is no pelican case it comes in a box with foam.

what was the reasoning behind buying two SMRs when the regular MRAD is a switch barrel? Just curious
barrels were on BO and the shop couldnt give me an ETA, I also have the disposable income, also have 2 M107A1's bought at the same time, cant take the money with me when I die so might as well spend it and enjoy it while im breathing.
How do you guys like the proof carbon barrels?
I'm still on the fence about CF barrels, though I have 2: a CA MPR in 6.5 PRC, & MRAD Conversion kit in 300 PRC. I am very happy with the 300 PRC CF barrel. 1 ragged hole w/ 250 Atips. Shot it to 1 mile @ Clinton House a couple of weeks back. No problem hitting 1 MOA tgt @ 1 mile. It seems to me there is more rigidity in the CF barrels and they are harder to monitor for temperature. In my limited experience with them it seems like I am only able to find 1 node. Probably better suited to a thread purely on CF barrels but I would love the hear other's experience tuning loads for CF barrels.
Hey another question came to mind... what are you using as an ammo case for the 33XC rounds when you take them to the range? Thanks.Makers kit "A" is the one you need.

Finally picked this up, need to make a bag rider now.
Got the TRG bipod installed after getting an Area 419 arca, clamp, and pic adapter. Gun is an “EJ” prefix in 300NM right now. I've only played with Hornady 225 ELD-M moving at 2,900fps, and the results were just okay. I have some Berger 215s I need to get shot soon, and I'm hoping for better results. I've put about 170 rounds through it so far, and it's a smooth-shooting beast. I was hitting a 10” piece of steel at 1,000 pretty consistently. With closer in targets, it’s boringly accurate.
I also have a 338LM barrel for it, but it has the older style bolt without the slot for the bolt pin. I spoke with Barrett and since the 300NM and 338LM share the same bolt head, I should be okay to run the same bolt with both, so long as the bolt headspaces with the 338LM barrel. That would negate any need for the breech conversion kit.
Still looking for a bag rider. Hit me up if you have one to spare!

Bought two nice multicam cases from Lungpunch Rigging on this forum. They hold 20 rounds each. Other than that a Peterson brass plastic box without a top.
Love my Area 419 arca rail!
Is that a Wilcox Rapter? How is it working for you? Do the civilian ones have the lasers dumbed down?
Nope...it's a MARS. I have experience with the Raptar, and I'm not a fan. The user interface is clunky and the overall construction is not as robust as it should be; think metal and plastic together, and guess which one gives first. The user experience with the MARS is much better. I've not messed around with any of the civ versions, but I'm guessing the lasers being dumbed down won't affect the average user. It may limit your ability range past 1,000 (depending on weather), but is that a capability that most people actually need?
Gun is 300 Norma Mag. Shot some Berger 245 hybrids and I was much happier with the results. Groups were shot from a bipod and rear bag at 100m. Average group size for six groups was .445 MOA, all measured with Ballistic-X. I was getting about 1-1.5 MOA from the Hornady 225 ELD-M. I need to play around with seating depths to get it dialed in, but I think it's going to be a good match.
I ran it harder than I should have for the first 50 rounds through the barrel and noticed some firecracking when I scoped it after cleaning. I'm at around 240 rounds now and it seems the firecracking has grown a little, but has overall seemed pretty stable. I also slugged the barrel and found two tighter spots (one toward the chamber and one about 1/3 down the barrel). I might end up lapping those, but it might also be an exercise in futility given how it shot the 245 hybrids. Maybe a rainy day venture.
I could have done better with a Mk22/MRAD bag rider....just sayin! So if you have a spare, let me know.

No one that I know of is making custom barrels. Bugholes and a couple other shops are spinning custom barrels from your barrel makers kit or donor extension. You supply the barrel you want customized along with the extension and barrel nut, and they put it all together for you.
Once I shoot out my factory 300NM barrel, I'm going to send the extension and a ModBB barrel to bugholes to hopefully stretch more life out of the second barrel.
308 300WM 300NM 338NM and with the weather warming up I will get to try the new ones out next week 
Question since I don't reload for now I am stuck with factory ammo does anyone know what bullets Norma ammo uses in their 300nm and 338nm rounds
Thanks a bunch! Magic link!
Mine shoots under a minute pretty easy with the 225 eldm , heres a 3 shot group at 100 when I zeroed( not a great baseline, i know) but I immediately took it to 1580 and then 1900 right after this

Is the twist rate fast enough for the .300/225 grain?
Could that be too fast for 225 ELDM?
@JohnDeereGuy1996
Twist Rate Stability Calculator
Our newly updated Twist Rate Stability Calculator not only tells you what your SG is, but it also lets you know if you are reaching your optimized BC.
bergerbullets.com My simplified 'Miller' for the 225 ELDM says 1:8.5, should be good. Have you checked case shoulder jump to throat shoulder? Unsure what's considered 'ideal' for a heavy .3, the 6.5 PRC 150 is arguably 0.002"-0.003" I believe. Or the factory bullet seating depth may not be ideal for the gun's lands as of today? Since you have such a superb seed-chucker, Id even call Hornady and ask them......
On a personal note, I'm guilty of vertical stringing quite a bit with a 7mm RemMag. Unsure if that's a factor of course but that central group has some 'vert' to it.
Sound thinking, good luck.
A couple of questions, which rings, looking at spurh , NF and Barrett. Any suggestions on ring models would be appreciated, seem to always buy the wrong ones. Are the 20 moa needed? Going to be used for elr, with a NF ATACR.
Thanks
Thanks

I never had much luck with factory Hornady 225gr ELDM in my 300 Norma. I know, different caliber, but similar enough and same barrel length and twist rate for MRAD barrels in both calibers. My average with the factory 225s was 1.3 MOA at 100m for ten five-shot groups during break in.
I've since shot factory loaded 215gr Berger Hybrids with an average of .6 MOA at 100m for five five-shot groups, factory loaded 245gr Berger Hybrids with an average of .44 MOA at 100m for five five-shot groups, and hand loaded 230 A-Tips at book length with an average of .46 MOA at 100m for five five-shot groups.
No one makes a receiver bushing for the MRAD, so I'm working on using a bore guide to get my jam length with those bullets. Once I have that, I can start playing with seating depths, but I'm not sure if I'll mess around with the 225 ELDMs again.
Also of note, don't be too hard on yourself when it comes to grouping magnums. They're not the easiest to tame, but I'd rather shoot a violent magnum than a tack driver .223.

Just get your jam length by removing the barrel. I do that with my DT and MRAD barrels
Anyone make the barrel wrench for the extension.
So decided to make a barrel wrench for the MRAD. They are really easy to take down. The lock collar and the barrel threads have blue thread locker on them about an inch above the collar line. Im going spin up a bartlien for it in 6.5 creedmoor.

17 or 24 inch barrel?
which cartridge
I know this is old, and forgive me if it’s been answered already, but is the Barrett tool kit fix it sticks? Or are they Barrett’s own product?
Pic for thread.

They are fix it stix, it includes specific torque limiters that aren’t otherwise available unless someone was dumb enough to pay for a kit and sell the parts that make it unique.
It’s likely how barrett plans to make money in their monopoly over the kit/limiters.
