How old is the trigger and estimated round count?

About one or two for every 20 to 30 rounds.

I've used a standard weight BCG NiB Stag and a lightweight ALU 3Gun unit and similar ratio of light strike FTF. Will not ignite when put through a second time.

Using Sellier and Bellot 123gr. What do you think I should start trouble shooting or is this a bad batch of ammo? Or could something be wrong with my fire control group?
