[QUOTE="SidecarFlip, post: 761518, member: 39764"] Here's where I am/we are, in as much as there are 2 V2's involved, mine which is new and Tom's (one of my hunting partners) who has had his for a while. The Internet and this forum are great stores of valuable information. Been reading about the blowby from the primer nor seating close enough to the firing pin retainer plus and allowing gas to escape. I also read that CVA/BPI had a shim fix. Of course no one has the shims available, not even CVA/BPI so I'm going to grind custom shims on the surface grinder to shim out both rifles for a slight interference fit. Tom has already experienced a siezed firing pin from blowby. Hopefully that can be fixed. I've also read the CVA has had some issues with incomplete burn/misfires using Blackhorn and offers a recessed breech plug, I bought 2 from BPI direct, one for each rifle. I'm planning on taking the stock plug and using it with white hots or possibly modifying it by enlarging the flash hole in 0.005" increments to see what effect the bigger diameter has on burn rates, accuracy and velocity and I may machine a pluf with a recess myself like the retrofit BPI plug has. We are looking at either Thor or Precision Engineering non saboted bullets as well as the Barnes TMZ's for increasing effective range. They will never be long range rifles but I have to say they are a cheap date compared to my centerfires and I can shoot them down here during deer season. I can't shoot a centerfire unless it's a pistol. I got a Nikon 3-9 BDC reticle in Realtree, the exact scope that Tom has. I wanted to make the guns as similar as possible so we can exchange or have either available for a hunt because we don't always hunt together. I had a bit of an issue with the factory suppled and mounted) scope mount. I checked the mount to bore alignment, clamping in a 3 foot length of centerless ground and normalized drill rod and the mount was within 0.010 parallel to the centerline of the bore but the ring upper half wasn't concentric with the lower half of the mount so I had to lap the ring halves with lapping compound and bar. I also sequentially pulled each mounting screw, applied a dab of threadlocker and retorqued them to 25 inch pounds. I clamped the rings at 25 as well after levelling the scope. I have to bench/bore sight it yet and go start playing with it and the chronograph. Gonna be fun..... [/QUOTE]
