Once again I want to thankyou for the response. I was able to find all my answers off your links. The linked manual is a big help. Unfortunately I can not find any H335 at the moment to purchase for the tracers, so I guess I'll hold off for the time being.
Not sure why I was calling them benchmark...I meant benchrest :-) Thank you for the clarification. I have plenty to go from from the responses and will start to see what I can devlope that the rifle will like. Thank you once again!
