Went back to the range last night. Sako ammo has not failed to fire on any occasion. Hornady failed to fire the other night, but with cleaned out bolt it did not fail to fire last night. Cheap Perfecta ammo has failed to fire both times even with cleaned out bolt. Must have harder primers but I am certain it is the trigger that is causing the issue by not pulling back the firing pin as far as factory trigger does. I will swap the factory trigger back in and try the perfecta ammo again and report back. Even if I was to carry on using the rifle as-is and only use Sako ammo, murphy's law will be that when i'm lined up on a trophy stag the bloody thing will just go click. Will either have to find a different trigger or maybe get a stronger firing pin spring but I worry that a stronger spring will decrease accuracy. I'm assuming there is a sweet spot in terms of spring force.
