Reloading / Re: trim length
July 18, 2012, 09:04:27 PM
Before you start trimming your cases it would be wise to invest in a "chamber length gauge" Sinclair # 740-000-783SB for your 6.5 Creedmoor (or other 6.5).  Insert the gauge into a fired unprimed shortened case and chamber the round.  "The insert will be pushed back into the case and you can then determine the "true" length of your rifles chamber, and how much excess case length your chamber may have".  Dont go the 1.910" trim length route if your chamber measures longer than 1.920".  My Savage LRP chamber measures 1.939".....  no trimming necessary other than to keep the cases uniform in length. ..YMMV

JFC....let us know how your batch turned out when you get a chance.  Lot #'s too please...Thanks.
Can't beat the price.  (Hornady) if you plan to shoot beyond 600 yards go for the Comp. Reddings.
Welcome to the site......I dont think Hornady really cares wether you use their Full length die for partial sizing or not.  Keep in mind that repeated firings at some point will require full length resizing and readjustment of the die (unless you use "Die Shims" between the die and the press) available from Sinclair #749-001-325SB set of seven.  Thats one of the advantages of having a separate neck die.    YMMV
Berger 140VLD (Hntg.) to lands 2.870" .........Hornady 140A-Max to lands 2.860"........Lapua 139HPBT Scenar to lands 2.813"....
Berger 140 VLD (Htng.) will be .015" off the lands at 2.855" O.A.l  (my LRP's chamber)... I post over all lengths, as not everyone has the proper tools to measure ogive lengths; and O.A.L. will get you close enough as ogives can vary also.  YMMV

Jay....The shoulders have moved forward and the cases require full length resizing.  Also when was the last time you annealed the cases?  The brass has become work hardened and will need to be re-annealed so that the neck tension remains constant or accuracy will suffer.  A Redding (6.5 Creedmoor) body die (properly adjusted) will push the shoulder back on those "loaded rounds" so that they can chamber and fire, in lieu of pulling bullets and dumping powder.  NEVER anneal a case with a live primer in it.  ::)
lal357...My Hybrid 100V load is 42.3 grs. with Berger 140gr.VLD (Htng.) O.A.L. 2.855" Fed 210M primers.  Very accurate... but more powder fouling on the outside of the neck than I would like to see.   Being that Hybrid 100V has similarities to ball powder IMHO it probably requires mag primers when you load over 40+ grains (like most ball powders do).  Metering is great, and I plan on using it more often, after I find out which primer gives me the least O.S. neck fouling.  Burning rate is a tad slower than H4350 but faster than H4831.   YMMV
I can vouch for John's sucess....he regularly shoots at 600 yards and uses (for targets) golf balls (painted black) with a small hook screwed into the ball, then suspended by string and hung in front of a steel plate painted white for contrast.   8)

Smart Choice.....Dont think you will be using that .17 Remmy for any long distance yotes while you have that Creedmoor.  Nice shooting...entrance/exit info?
Reloading / Re: Neck turning
June 23, 2012, 12:14:53 PM
Trent....Problem is turning the necks (factory brass) to uniform the thickness wont correct the rest of the case.  If the neck is thick on one side, the remainder of the case will also be thick on the same side.   Sort your cases by uniformitity of neck thickness (runout) and keep the ones with the least variation for long range competition.  More  cases are ruined by people who think they must neck turn when it isnt necessary (excluding a tight necked chamber).  Checking each case for consistency of neck thickness will do more to shrink groups than taking a lopsided case and turning the thicker side of the neck down, thinking you corrected the problem when IMHO it is a bandaid approach.  Either the case is uniform in thickness or its for sighters or informal shooting.  YMMV
One thing I would like to point out... (I mentioned previously) is that a donut will be formed inside the case where the neck joins the shoulder.  (More common when forming 6.5 CM from .308 brass and some .243 brass).  After the "required" neck turning, the formed case must be "FIRED" and the inside neck reamed BEFORE resizing a "FIRED" case to remove this donut.  Afterwards the case must be annealed as it has become work hardened in the first sizing/forming process and then resized again before loading.  I recommend the "Bench-Source" annealing machine to produce consistantly annealed cases.   Most shooters do not anneal their cases often enough... if at all.  BTW....The most concentric cases I have formed for the 6.5 Creedmoor were made from 100 new Lapua .260 Remington cases; they have produced the tightest groups I have ever fired at 600 yards. YMMV

So coooool....I want one of those watches.   BTW did you marry that girl yet?
General Discussion / Re: cleaning 6.5
June 17, 2012, 11:17:12 AM
Hollands Shooter's Supply Inc. sells a product called "Witches Brew" Bore Lube (also available from Midway).  It minimizes fouling and is applied after cleaning your bore; follow with a dry patch and you are ready to continue shooting.  I do agree with fouling/ranging shots prior to going for score.   I have read many times not to shoot on a dry bore "after cleaning" so ....  what ever floats your boat. YMMV
My suggestion is to buy a 6.5 Creedmoor Upper (DPMS) from Midway USA (or your local dealer) and keep the  R.R. .308 upper as is.  This way you can have the best of both worlds.  Im pretty sure the lower would be compatible with the DPMS 6.5CM upper.  YMMV
