These are all .264 caliber rifles. The top rifle is 8 pounds 10 ounces as it sits. Personal preference, I would prefer not to go heavier. The bottom two are about 7 pounds 2 ounces. While none are competition rifles, they're all capable of shooting groups, though I have never tried more than 5 shots without a break. The idea of only shooting 1 shot accurately due to barrel limitations doesn't seem based on experience; it seems like nonsense.
