Tuning Maverick shroud

Okay I just changed the whole Barrel assembly over to the 700 mm with heavy liner. I'm shooting 25 grains. I upped my FPS about 50 ft and about 4 clicks right 4 clicks down and I was zeroed @ 42. now I'm shooting 879 FPS on 3. 130/ 100. I want to be able to shoot 34 grain and slugs. It's raining today and cold so we'll have to wait for another day. I'll put the big bottle on it and step out to my bigger range tomorrow! Looks like it's going to fine..



THANKS TO ALL, FOR ADVISE! remember we're All Americans! A fact that allows this day to exist!
