I've got about 450 rounds through my 7 Saum now and have been shooting the same load for about 350 of them. 60.9 grains RL26 with a 180 vld hunting and Cci 250s with ADG brass. Shooting right at 3005fps. This loads given me es And SD's consistently single digits. And shot 1/2 minute consistently. I've even shot this sub 1/2 minutes at 1050 yards. This summer I began testing 184 hybrids and had solid results and worked up to 61.5 grains of rl26 for 2978 average with zero pressure signs. I then loaded some at 61.7 and once again had zero pressure signs and was shooting about 2995 FPS with an ES of 10.
Fast forward to the next range trip and that same load along with the 61.5 grain load gave me clickers. (Twice fired brass on these loads with 184 hybrids) I decided I'd try my proven load with the 180 vldh mentioned above (6 firings on this brass) to verify things are good, clickers with that load as well. Put over the Labradar and velocity was still exactly where I left it. With very tight ES, and SD. Only thing I did notice is that they were slightly tight on bolt close. I stopped shooting and returned home to investigate further. Only issue I could find was the primer pockets were fairly dirty, and possibly holding primers out more then normal. But with one set of brass being 2x fired and the other 6x fired have a hard time believing this is causing clickers in both sets of brass.
Any ideas or input? I've since unloaded all ammo, deprimed and cleaned all primer pockets. My next move at the moment is to load a ladder with both bullets and check again. Unfortunately I'm in Washington and bear opens Sunday. Leaving me nothing but my 6.5 creedmoor dialed in. I'll use it but severely cuts my distance down
