My current 257(700LSS) likes R25 and 7828 under the 100g Barnes pills. R25 is the speed winner if that's of interest. Haven't ran the MKs, but the 115 VLDs are pretty sweet at 3500. I have a couple boxes of the Swft SCs, but couldnt get them to shoot worth a darn in this particular rig.

Building another as well with a #4 Rock 1/10 at 25in. Hoping it will dance with the Swifts. That pill has alot going for it.
