SLG not chronoing consistently
I have an SLG '09 and the other day at the field I was chronoing it. It was all over the place. It ranged from 230-280 on 5-6 shots. I have changed all the major o-rings and the bumper and have lubed the o-rings. Regardless, the problem has persisted.
There are no after market parts in the gun and I use the stock barrel. I was shooting new Draxis paint and using a steely tank. I have an Halo feeder, but I do not think that really matters.
Can anyone help me?
