Which Barrel Next



  • I now have a 2000+ yard range that will be available to me a couple times a year. I am currently shooting 308 out of my dta, but am getting the itch for something bigger.

    6.5 creed is probably the sensible answer and may be what I end up with, but at this point I really want something bigger.

    I have heard it said that there are rounds out there that are much better ballistically than the 338 lapua. I am looking for information and thoughts on these rounds. Only limit is that it has to fit in the AR's platform.

    I am not in any hurry and it will probably be 6mo-a year before I can get anything else, but I am wanting to start doing the research.



  • Stupid phone won't let me scroll anymore when in typing mode so I can't edit the bottom half of my previous message.

    I meant srs platform...obviously not the ar platform.



  • Lol, happens to me all the time.

    I don't have any experience here, but I like what the 7mms have to offer, especially with Sierra offering the 183 SMK and Berger offering the (I believe) 195.

    If the 7lrm could push those at respectable velocities those would be interesting, I think.



  • Why be sensible? Your talking about use a few times a year and going to 2000 yards.

    I also like the 7mm rounds. But don't know enough to point you in a direction.



  • I was under the impression you own a 260 Rem, made by TacOps none the less! I'm given to believe that, and 6.5 CM are more or less the same thing. I understand the ergonomics are obviously different, but I couldn't justify it to myself to have two different cartridges so close to each other in performance. To each their own, I suppose

    My "Because I want it" list goes

    7mm LRM pushing 195 Berger Hybrids.
    Get those suckers going ~3000 fps and let that .755 G1 work for you. At 3000Fps those go subsonic at 2K yards. You do need a 8 twist to do them right I believe. Personally when I do this one I'm going to do it in a "lighter weight", conventional style, full custom action/stock/barrel for long range or bigger game hunting. I want elk to fear me out to 1500yards. But I'm going to do a 20" deer/pig gun first, not sure on the caliber.

    .300 Norma Mag. 230 Berger hybrids. Again going 2950-3000 FPS those make it to about 1850 yards supersonic.
    .338 Norma Mag. Mostly because I want something other than a Lapua. 2650ish with a 300 berger hybrid makes it to 1750 ish.
    These two (or whichever I eventually pick) will probably go into a DT

    I do love these hypotheticals.

  • I have a 260, but it doesn't have a scope on it. A barrel is cheaper than a scope. Beauty of the dta...but yeah...I really think I want something bigger.



  • @dddoo7

    Eh minor detail.

    I don't think a 6.5 anything is going to make it to 2K with the type of accuracy you're looking for.

    And it doesn't really qualify for the bigger you're looking for.

    6.5-338 lapua? Lol

    Talk about a barrel burner lol.



  • @dddoo7

    I had to check, and run the numbers..... its a thing.....

    Does benchmark sell barrels in a bulk discount, cause you'd need them.

  • I ain't gonna do anything crazy overbore. Time I get the load development done the barrel will be toast.

    The 7LRM looks interesting. I'm courious about recoil compared to 338 lapua. Also suppression through a 338 suppressor as I assume there is probably not a 30 cal can that will handle it and have the volume to efficiently suppress it.



  • @dddoo7

    Unfortunately I don't get to suppress anything out here so I can't comment.

    But wouldn't a 300 Mag rated can be able to take the pressure? A TBAC Ultra 7 (I figure you have something similar) is rated to 7 RUM in a 20 inch barrel.

  • I have a 30p-1 (9"), but I don't imagine it has enough volume to effectively suppress it even if it can handle it.



  • The next good thing about that SRS is the man you've bought it from probably knows all the things. But I think he's out huntil speed goats.



  • I run my 338 LM suppressed. I use a griffin armament 338PHS. It attaches over a brake. I run this can on my 300 WSM also. The nice part is just get another brake adapter and run can on multiple guns, but for a DTA all you would need is one can. I think the recoil feels similar to a .308 with no brake. Do not have anytime behind a 7MM of any sort so cannot compare.



  • I have done some more reading and I am liking the 7mm magnums. Looks like they will be more effective at longer ranges than the 338 lapua even though they have less horse power behind them. They will also be much cheaper to shoot as everything from bullets to brass are cheaper. Only thing I can think of that will suffer with the 7mm's is barrel life, but they will probably still be good for maybe 1500 rounds?...or is that optimistic?

    I don't think a 6.5 will out do a 338 lapua unless it is a 140 class running 3500+ fps at which point barrels are going to melt very quickly.

    Does anyone have experience with the 28 nosler? It looks very comparable on paper to the 7lrm. what are the differences? how does it feed in a DT mag?

    It looks to me like the 7 RUM uses a whole lot more powder and only gains a slight FPS advantage over the LRM and nosler. Probably not worth the extra recoil that no doubt will follow.



  • I'm going to follow this with interest, as I'd like one of these in my future.

    Theres a couple threads on LRH, regarding this topic.

    http://www.longrangehunting.com/forums/f19/7mm-lrm-vs-28-nosler-ballistics-149796/

    This is what they decided was the order of power.

    7mm BR
    7-08 Remington
    284 Winchester
    280 Remington
    280 Ackley Improved
    7mm RSAUM
    7mm WSM
    7mm Rem Mag
    7mm Weatherby
    7mm LRM
    7mm STW
    28-Nosler
    7mm RUM

    And heres a picture Orkan posted on sniper forum

  • 7LRM is my favorite 7mm magnum. It has the widest and most forgiving accuracy nodes of them all.

    If more power is needed, 300NM is the go-to ELR cartridge. The 338LM isn't really even in the running.

    How does the 7 LRM do through a 30 cal thinderbeast? How about through a 338 LM suppressor? Is it tolerable or still very loud?



  • I shoot my 7LRM through my DT338 can all the time. Nothing noticeably loud about it. Thunderbeast 30cal ultra's work fine too.
