[QUOTE="Muddyboots, post: 2160254, member: 63925"] Yes, there can be serious issues from using loads BELOW minimal starting point. Insufficient load density can result in "detonation" due to air to powder density. This phenomenon is a controversy by many but I have been told directly by Alliant and Hodgdon tech line it is a real issue to be aware of and do not go below minimal load thresholds. The minimal load for the 140 BT is 47.9 grain = 2567 fps. Nosler typically uses same load data for same group of bullets. Since the 6.5PRC is in competition to their 26 Nosler, they do not have 6.5PRC load data. The recoil from this load in a 7.5LB rifle is 14.5 LBs which is not very much at all. The recoil velocity which is a bigger teller of potential is 11.14 fps which is not very fast. I would show your wife the data so she can see it is not going to be an "Oh Crap" when she pulls trigger. I estimated the rifle weight and bet it is heavier so the recoil would go down even more. I would rethink loading below minimal load recommendations just for safety reasons. plus the recoil at minimal is very low.[ATTACH type="full"]263717[/ATTACH] See example 6.5PRC loads from Hodgdon powder website: [ATTACH type="full"]263714[/ATTACH] [/QUOTE]
