700 mm 30 cal

I have had one for a couple of weeks. .25 shooting 34 grain JSB. 106 yard sub MOA. The original ST would shoot MOA. Maybe less fliers with the X. Only have one tin through it. Makes the gun longer with the fixed moderator. Was shooting the 34 grain at 840 fps on 5 with the ST. Changed to the X and it was over 900. Dialed back to 3 to get 850 and 880 at 4. So more shots per fill. Good luck. sylvan
