Pop Quiz: Name the Rifle Calibers

As I put a new review rifle in my safe, chambered as it was in a caliber I’ve never owned, I wondered: Just how many rifle calibers do I have in stock in my house at this moment? The answer was 18. But the question, for you, is can you identify them all from these photos? Click ’em to enlarge ’em. Go!

      “(If you really wanted to mess with some minds put a 32 win spl here)” I was getting messed up with the ogive colors. ­čÖé

    3. avatar Jeremy S. says:

      Really close, Andrew, but juuussst a bit outside.

    4. avatar dsrd says:

      third from left is .22mag and I think third from right is .300WM, otherwise I agree with Andrew

      1. avatar Andrew Lias says:

        I believe you are correct.

      2. avatar uncommon_sense says:

        Me three!

      3. avatar Jeremy S. says:

        Indeed, dsrd, with your corrections that makes the correct list!

    5. avatar Kenneth says:

      #3 is the .22WMR. The hornet is a bottleneck round. Real close tho…

  2. avatar Darkstar says:

    I’ll bite My guess from L to R (1st photo): 22 short, 22LR, 22Mag, 30 Carbine, 5.56×45, 300 BLK, 243, 7.62×39, 458 SOCOM, 260 rem, 6.5 Creed, 9.3x74R, 308, 7.62x54R, 30-06, 300 Win Mag, 338 Lapua, 50 BMG

  6. avatar Mr.Savage says:

    my list is identical to Andrew Lias’ list, no point in re-typing I guess.

  7. avatar BLoving says:

    Most of what “most” of you have guessed looks right EXCEPT: What y’all are calling 30-30 looks more like a .44-40win.

  8. avatar TP says:

    The picture is showing 18 cartridges but only about 10 CALIBERS.

    1. avatar Jeremy S. says:


  9. avatar Velvet Elvis Gun Guy (formerly Timmy!) says:

    “…can you identify them all from these photos?”

    I am secure enough in myself to honestly answer: No, I can not.

  10. avatar GS650G says:

    A better quiz is which ones are banned or restricted either by caliber or by the gun they are used in

    I got this one on Instagram so I won’t spoil the fun here. I’m looking forward to expanding my collection into a few of these calibers, especially since I’ve started reloading.

  13. avatar Connie says:

    No .45-70!? How could you….

    1. avatar Jeremy S. says:

      I had some here the week before these photos were taken, but it’s now in stock at TTAG’s secret above ground bunker plus some with JWT for a couple review rifles he has in the caliber.

    1. avatar Jeremy S. says:

      To be perfectly correct you’d have to swap the 6mm and 6.5mm Creedmoor as the 6mm is on the left in the pic, but I’ll give it to you because it’s freaking hard to tell the difference visually!

      1. avatar Burley says:

        Thanks! Yeah, .020 is damned hard to spot in a picture, especially with the 2 cartridges being of a different color, one much more reflective than the other…

  23. avatar Fletcher says:

    Wonderful blog you have here but I was wanting to know if you
    knew of any discussion boards that cover the same topics discussed here?
    I’d really like to be a part of online community where I can get feed-back from other experienced people that share the same interest.

    If you have any recommendations, please let me know.
    Appreciate it!

  24. In theory, there’s enough information on the internet for that you figure out how to do that all on your own;
    however that probably isn’t a very good plan. You
    won’t be able to just find a strategy and
    spend a while each week working on it. That’s exactly how we women entrepreneurs want people react when visiting our sites.

    The process begins in the uncomplicated activity of your account option. There these folks were, anticipating their forthcoming
    experience and joyously reliving the final one — Peter,
    Susan, Edmund, and Lucy, within the guises of actors William Moseley (now a dashing 20-year-old), Anna Popplewell (a newly minted Oxford
    freshman), Skandar Keynes (with vocal octaves further at 15), and Georgie Henley (approaching teenhood,
    an excellent six inches taller than we last saw
    her). Now you’ve taken that all-important 1st step and so
    are reading this article report about flash games and social network, you happen to be in the unique and privideged position to
    be amongst a small grouping of pioneering entreprenuers who know relating to this and therefore
    are taking affirmative action.

  26. Would love to perpetually get updated outstanding blog!

    When someone writes an paragraph he/she retains the thought of a user in his/her mind that how a user can understand
    it. Thus that’s why this post is perfect. Thanks!

  28. Being a weebsite deaigner or perhaps front-end developer SEO cann be your

    SEO strategies thatt put them near the top of SERPs
    results, garnering valuable clicks that they can convert into qualified leadss
