Powder weights from 40.5gr to 43.5. First 2 shots would touch. 3rd shot varied between 1/4 to 1inch apart from the first 2. And never straying in the same direction. For example 40.5 gr first 2 shots would touch. 3rd would hit upper right 1/2 inch away from the first 2. With 43.5 first 2 would touch. 3rd was 3/4 in lower left. Any ideas on what would cause this? There was about a 3-4 min break between shots with 10min between groups. Using a Savage 10t with a 1-10 twist. --- End quote --- It could be a matter of cheekweld. You may be able to be consistent for a couple shots then you position changes. You might try shooting 3 shots in a row and not pick your head up of the rifle while working the bolt. Try to find a reference point on your face where it touches the stock and keep that position the same. Identical concept to an anchor point in archery. I am leaning towards form since you are always getting two shots to touch and there is no consistency where the 3rd is going. --- End quote --- Hmm.... I'll have to try that. If it was that simple I might kick my own butt for that. |

building an AR10 (DPMS) looking for a 22" 7.3 or 7.5 twist barrel in 243. Want it to be relatively light, but also hold zero for strings up to 15 rounds per stage. Using a JP lightweight carrier, and a adjustable gas block. what contour on the barrel, and will you build the barrel assembly? |

I certainly wouldn't go any smaller than that. Unfortunately, I don't do any AR10 barrels at this time. I used to, but unless a guy had a premium upper, accuracy was hit or miss. Had the most problems with DPMS uppers and their consistency. Drop the same barrel into a premium billet upper and they shot lights out. |

Do you do any re-barreling of metric threaded actions... Weatherby, Howa, etc? |
