6mm 105 and 107 velocity debate. How fast can they be pushed.
Hey guys, I ve decided to build a 6x284, and I am going to design it around the 105 and 107grn bullets. I spoke with Krieger, and they recommended I use a 30", 1-8.5 twist, 4 groove barrel, for 105 and 107grn bullets out of the 6x284.
My question is, how fast can I push the following bullets out of the above mentioned twist rate and groove without them blowing up.
1. Berger 105grn VLD
2. Sierra 107grn Matchking
My goal is to push them around 3500fps or faster. I will be using a Nesika Model L, 1.470 Diameter action.
