The 7-08 is hands down my favorite centerfire round in a speciality handgun, it's relatively mild on recoil, easy to load for and tack driving accuracy is common for the cartridge.
I've had or do have Xp-100's, a Savage Striker and four different Encore barrels in the chambering.......being a sucker for the round I just picked up yet another (slightly used) 15" TC factory barrel this past Sat. morning.
I'm also fond of Varget (almost identical to IMR 4064 in burn rate) and every 7-08 I've tried it in so far has liked between 40.0 and 41.5grs of Varget under a Sierra 130gr SSP and a CCI BR-2 primer.
The one 15" barrel I didn't try Varget in was my very first TC factory Encore barrel back in early '97' when the Encore was just starting to become available, it would print five round cloverleaf 100yd groups all day with a Sierra 130gr Sierra SSP over 38.5grs of BLC-2.
