    Shilen nomenclature

    Can anyone tell me what these markings mean at the end of a Shilen barrel?

    Thanks,

    Jay

    Does the SM indicate select match?

    SM is "Select Match", the standalone "S" is stainless. "6" should be the groove count. I'm not certain on the "RF". The last few Shilens I ordered didn't have that mark.

    These people may be able to assist in explaining the stamping on their barrel Blanks.

    I sent them an email and tried to call on Friday but apparently it was too late. I assume they will not get back to me until sometime Monday or perhaps later. Which may be too late as the reason I am asking is because this apparently LV barrel is on GB for an excellent price if it is a select match and I am hoping I could find out before the listing ends.

    Thanks,

    Jay

    You do realize that a 14 twist will only handle up to about a 60 grain bullet right? Berger even lists a 12 twist requirement for their 69 grain high BC varmint bullet. I don't know what your intended use is though.

    Yes, I am well aware. My intentions on buying this barrel is to have another high quality 6MM barrel to put on my Panda. I currently have Bartlein and Hart, now I want a Shilen.

    shilen nomenclature

    14 twist 60 GR?????? 6mm
    many use a 14 twist and shoot 68 to 72 gr bullets in the PPC with great success
    Maybe you were thinking 224 caliber.

    The stamp on this Shilen barrel blank(SM) indicates that it is a "select Match" barrel . If you like the price, why not add it to your list of quality barrels. Who knows, it could be a "hummer". I've got one,Shilen,("Select Match") blank, that's stamped "SM"

    The comment about a 14 twist only being able to handle bullets of 60 grains and lighter is incorrect. For years before the discovery that a 13.5 twist may be advantageous for longer bullets short range BR bullets, 14 twist barrels were the most common in benchrest competition, for all of the common bullet weights, the heaviest generally being 68 gr (made using .825 jackets). If one wanted to explore the advantage of more stability, without changing barrels, all that would be required would be to switch to a bullet made using a shorter jacket. It is the length of bullets of a given caliber, rather than their weights that determines their twist requirements. Bullets of medium weight (65-66gr) are made using both .790 and .825 jackets. Other manufacturers' jackets fall between these lengths.

    Id say a 14tw is the most popular twist ever for 62-68gr bullets. I bet if you called walt he would even say that. Those computer calculations are wrong

    Maybe I am wrong........so should Berger be changing the info on their site?

    69 gr High BC FB Varmint 0.289 N/A N/A 1:12″ 24313

    65 gr BT Target 0.281 0.144 1.092 1:13″ 24408
    65 gr WEB BR Target 0.246 N/A N/A 1:14″ 24409
    68 gr FB Target 0.255 N/A N/A 1:13″ 24411

    I'm more of a long range guy, but I guess if it works, it works.
