[QUOTE="JustC, post: 36186, member: 817"] I have a 21" Hart 1:11.25 and with factory winchester supreme match 168gr SMK (the only factory ammo that fits the .336" neck) I am getting 2710fps [img]images/icons/shocked.gif[/img] I think the powder is temp sensitive because groups have grown this summer from the tiny ones this winter. Will be using Varget with the 165-175gr pills very soon. Brass is prepped and ready [img]images/icons/grin.gif[/img] I would think 2550fps-2650fps is very acheivable in your tube with the right powder. MHO [/QUOTE]
