Today shot 9/53 4759/H4198 again today was 11 degrees warmer. Figured todays velocities would be faster, was not the case. They were actually slower, go figure. Also shot 15/60 4759/H322, that one shot well also. 61 degrees 2749 2732 2732 2726 2743 72 degrees 2710 2704 2677 2699 2699  |

Dennis........very realistic targets. Finally someone who does not go out and shoot bug holes every time. Good solid groups. Unfortunately, this is what happens when you play with different loadings. Some shoot extremely well and others just "so-so?" Some will shoot relatively consistent groups but every once in a while get you scratching your head  Typically four good ones with one out? Been there done that many, many times? Edge is probably on the right track with the bullet alignment inside the sabot/bore. Something, if in fact it is so, we do not have much control over. I am thinking about a muzzle guide made to very tight tolerance which will hold a very short starter. It will have no spin-jag. Just straight walled and recessed for the bullet nose. The fixture will be a very tight fit over the muzzle. The bore will very closely match the diameter of the starter rod. It will be just long enough to get the bullet below the muzzle. From there I will use my present spin-jag "longer" starter and then on to my fat brass ram rod. Richard |

Seems that as being the norm.Your theory of the bullet starter is interesting. Would be interesting to see some tests to see if it would tighten up groups any.

Richard. That is a good thought. If most of the misalignment is from the initial start of the bullet you may have one more way to help shooting with a sabot. It will be interesting to find out.

As Edge mentioned in Rangeballs post on the New bullets, the recessed area in the starter should also match the exact nose shape of the intended bullet. If not, even with a snug fitting starter, the nose could be misaligned in the sabot and still seated that way. It would almost become necessary to build one starter for each bullet? "Bedding" the recess in the starter to a specific bullet.  "Tell me this is not getting to be more about paper punchin' accuracy than deer killin' accuracy ;D ;D" Richard |

Maybe something like the 45 cal barnes aligner tool for the xtp/nosler/MZ type bullets?
