Re: trimming the bullet meplay for better BC

Thanks for your imput , I have set up a tool to trim the meplat and start to make experiment at 1000 yards ( our shooting range allow 3200 meters of shooting range ...)

To Brent

I use vibration pannel rather accoustic target , vibration pannel are made with sismic detector from miltary surplus glue on pannel ( 2 pannel spaced with 1 meter ) and a HP counter 5334 purchase from surplu stoo that less costly than a new Oeheler with accoustic target , you can use too contact pannel made with 2 alumiun foil stick on cardboard that primtive set up but that work fine for a low cost

good shooting

    Jeff,

    I should have said, what's that rifle you were shooting? [img]images/icons/smile.gif[/img]

    I didn't catch the fly on the bull there at first, was just looking at them tiny groups. [img]images/icons/grin.gif[/img]


    Dantec,

    How exactly does a vibration pannel work? Any pictures of one?

    If you guys don't mind humoring a novice what exactly is trimming the meplat?-- Are you guys actually shortening the bullet by taking a measured section off the tip?? If so wouldn't that lower the B.C. as well??

    When trimming the meplat you remove just enough to make the tips of the bullets the same making for consistent BC. Important in competition.

    The reason i started to modify the point(meplat) was to reduce the amount of batches i end up with...To start i get as many bullets i can (500 to 1000),sort into Aol batchs of 5 thou ie #1 lot 1.325 to 1.330 and lot #2 1.330 to 1.335,i throw the highs and lows in the fire form/fouler bin then cut off the tips until i have 2 only batches of the same length ...I then put each bullet into a device i made that looks like a pencil sharpener with an adjustable stopper on the meplat end ,then u turn the bullet by hand and the cutter makes the meplat dia uniform....This is of coarse after they have been classified into lots for base to ogive length,bearing surface length and weight..Many hours later i hope i got best i can..JR ..Jeff Rogers.. pic of bullet uniformed next to one straight from the box
