If the neck of the fired cartridges aren't blowing out, it could be that Remington, in order to preserve us and cover their own rear, has loaded them with a fairly slow burning powder so as to keep pressure down. The 40,000cup loads I fire in my Krags will blow the ID of the neck out to .314-.315 or so. That can vary with the thickness of the brass in the neck. A bore with a groove diameter larger than .308, which many Krags have, will also produce less pressure. In other words, you've got nothing to worry about. Murray KY! I'm a Murray guy too, Murray City, OH that is. Maybe someone that buys the overly expensive stuff can pull one down for me and report what they find.
