It works fine with the Remington ammo haven't tried anything else except the Nosler.. maybe it just don't like them..but for the cost of the gun it should should anything..I'll see what CA says..
Picked up a Mesa fft 300 prc in August. It's light and shoots really well. Hand loading 190 grain Hornady CX at 3015 fps. Not really a complaint, but the bolt isn't really that smooth. While it isn't hard to close, it definitely feels snug even without chambering a round. Also notice with shells in the magazine, cycling rounds scratches the brass slightly. Overall, I'm pretty happy with the rifle and would buy another if I was looking.
