[QUOTE="backwoods83, post: 850955, member: 29890"] Simple answer is, they need to know base to ogive length to cut the throat. The real question is, which 7mm cartride are you going to use, with the STW and RUM the freebore would have to be less than .080" for bergers to touch the lands and still fit in the magazine, with the 7mm rem mag .125-.145" is plenty, as would be for the 7mm wby mag, but out of the 4 I mentioned the 7mm rem mag would be the only one safe for factory, all others with there higher pressures and/or case capacity need .200" freebore to keep it safe for factory loads, just in case you get in a bind and have to use some.
