Gander,

I have the .45 CVA Magbolt. It took me awhile to get it dialed in - I free-floated the barrel and bedded the action with Acra-Glass. After that, it's been a great shooter with sabots (XTP's, SST's & PR bullets). Several different combos all shoot around 1.75" at 100 yards. Best group so far has been the SST's with a 1.25" group. I know you shoot Powerbelts mostly - I've only put about 18 PB's through it - all the 225 grain hollowpoints. One group with the PB's was really good - about 1.5", (70 grains FFG 777), but when I started using FFFG and messing around with the powder charges, they started flying all over the place - looked like Ray Charles was behind the gun
