Thread: Barrel length question.

  1. #1

    Barrel length question.

    I've come across a .243 blaser barrel, which sounds quite tempting but the guy at the shop says it measures 20 inches/ 50 cm. My other barrels are both 57cm/ 22.5 inch factory standard. (And that's what's on their website too). I'm guessing this one may have been cut? And if so how much velocity would it loose for those couple of inches off? I was mainly going to set it up for foxing with a separate scope so velocity loss would be a concern. Thankyou.

    I looked into getting my 243 cut, I was told/ found on the net that i would lose about 47ft/sec per inch cut off. Wether this is right or not I don't know, I never got the barrel cut.

    Thanks. I've just been on the blaser site and they do do a shorter version at 52cm. So I'm guessing its this one as opposed to the 57cm standard.

    I have a factory supplied 52cm long 243 R8 Barrel, and at 10 meters the chronograph gives 2893ft/sec or 882m/sec for 100g loaded with 44g N160. I don't find a problem with it.

    Speer 100gr SPBT 1220. I also used Sierra GameKing 100gr Spitzer Boat Tail 1560 but not checked with Chronograph but point of impact is the same as the Speer 100gr.

    Sorry just remembered that the 882m/sec is through a ASE Utra SL5 Moderator on the 52cm barrel.

    Just be up front and ask the shop is this the factory length? Is it threaded as the thread size will also give you a good ideal about its original length/ origin.
    cheers

    Hi dickie. Yes I spoke to the shop. I think it's all factory standard after looking at the blaser website and talking to the shop. It's just the shorter 52cm, and threaded 15 x 1 with spigot, which is same as my other barrels and handy as I can put an existing moderator on it.

    Would the shorter barrel affect stabilising 100 gr bullets in any way??
