[QUOTE="RT2506, post: 1892546, member: 10178"] Well first off you broke the first rule in hand loading. You started with a MAX listed load. Then you broke another rule. You changed components in a load with no drop in powder charge. You should choose which ever components you want to use and stick with them. If you want to use the Federal cases I would back off 2.5 grs and work up in .3 grs at a time to see what your groups are and pressure signs are since you don't have a chrno. No two rifles are exactly the same so what was OK as a MAX in the Nosler test rifle may not and seems like is not the same as YOUR rifle. If you are having sticky bolt at 50* then at 80 or 90* you may rupture primers etc. Since there seems to not be that much difference in case capacity between your case makes it could be that the Federal are softer and thus expand and flow more and grip things better. Cases could have different neck wall thickness. Also from what my buddy and I learned way back when the 260 Rem came out which was before you could get 260 Rem. cases is that using 308 Win cases necked down left the neck pretty short from what a trim to 260 is supposed to be. That changers neck tension. We found that 243 Win necked up worked best. [/QUOTE]
