Skeet,
Mine has always shot very well. It is a modle 591 the clip feed rifle. I have shot the Agillia ammo and it shoots sub MOA, 0.81 for three 5 shot groups. Not too shabby for a 39 year old production rifle. I must have been lucky as I never had any problem with the Remington ammo. My source at Remington told me that the reason for Remington stopping production was that the 5mm was not competing with the 22 mag. Even though it was a superior cartrige. Much like the 6mm Remington and the 243 winchester. The 6mm had too slow of a twist to stablize anything heaver than 85 grains. Although these two are much closer balistically than the 5mm and the 22 mag. It is that old metric thing again. Let's hope this time people will take a look at it and let the round speak for itself.
