I am getting ready to reload some varmint rounds and have some brass that is sized out to +/- 1.741 instead of the 1.750, has anyone ran into this problem and what did you do with what results?
Thanks, Jeff |

Thanks, Jeff Are you saying that after sizing yourcases are shorter than the recommended trim length? I don't worry about it at all. Just make sure you clean the chamber well as you may get some carbone buildup in the chamber at the case mouth end and theoretically subsequent firing of a longer cased round could result in increased pressures if case mouth relief is inadequate to release the bullet. But that is not too likely with what I think you are describing. Just loadem and shootem. |

Thanks, Jeff Jeff, 1.741" case length is fine. I suppose by "varmint" you mean more accurate than the normal plinking stuff? If this is what you mean then I say consistency is more important than actual length. But even at that variances is case length will just change neck tension and the difference is so small from say a case that is .010" shorter or longer than the next it may not be even noticeable accuracy wise with a "standard" (non bench rest competition) rifle. Also for your varmint ammo I suggest you don't crimp it. If you must crimp do it in a canalure. If your varmint bullet don't have a canalure don't crimp. BTW: The SAMMI spec for .223 brass is 1.760 +zero minus.030" (Same for 5.56x45) |

1.740 is the minimum recommended length so your still in the clear, it's just not "optimal". Someone may be able to confirm what I believe I saw, that RCBS actually recommends 1.740". Worst case, load it, shoot it for fun and grow that baby out  RCBS recommends trimming to 1.740 (or .020 under maximum) for the first time trim when using an X-Die. I don't recommend it, but some people love it. If a case doesn't touch the blades on my trimmer (because it's under 1.750), I toss into the 'Plinking cases" bucket. |

Very interesting that you say the FC is short, as that is what I have and seems to be consistently +/- 1.741.
Thanks for the response. I loaded up some different loads to try and see what shoots best out of my rifle. I think i found a good load... http://i1221.photobucket.com/albums/dd468/doesgo73/IMG_20130619_191805_743.jpg Thats 5 rounds at 100 yards with a 50 grain varmint grenade. I think I found the load to produce! BTW, here's the rifle: http://i1221.photobucket.com/albums/dd468/doesgo73/IMG_20130619_191429_169.jpg |
