I have a Rem 722 rebored by JES. It's a fantastic shooter but keep the copper solvent handy. It's the only rifle that I shoot factory ammo in, and it prefers the cheap Federal Fusion 200gr. Just not able to match the combined velocity and accuracy of that stuff. The most promising handload I've found uses the 200gr Woodleigh and 8208XBR. I also tried the Nosler 200AB and Barnes 210gr but they are long for weight and eat into the powder space quite a bit. Next up is the 185TTSX, but haven't gotten around to it yet.
