I would never give up pump stroke smoothness for 30 FPS gain. It is not like you are going to shoot a case a game with a pump anyways. Besides I run my S6.5 @ 300 PSI with IVG flush on the stock bolt.
My breech and bolt are both very worn. I mean I have multiple gashes down the breech. I would say I have over 100 cases through mine (in the almost 3 years). It still shoots like a champ. I think I might switch out the bolt with another stock CCM one.
BTW I think your gain is because your CCM T2 bolt has 3 detent slot while u only really need 1(what Hush bolt has). CCM did it so they can use the same bolt for both the S6.5 and T2
