When you say "less effective", is the difference in performance,
a) really obvious, and
b) worth the trade off for the reduction in weight?
Having started using a T8 on my 243, I'm impressed with the performance but less so with the weight of the supressor and the affect it has on the handling of the rifle. I'd now like to get a mod fitted to my 308, but would like summat lighter than the T8.
