No Patrick it does not explictly say it is for the M41 only, it simply states the M41 just happened to be the rifle chosen for final testing. IF this data was intended soley for use in just one model it should and most certainly would say so in bold print. Imagine, in this lawsuit happy world, the liabilities a company would face by not making such knowledge known to the end users. As for the disclaimer, it's found in all loading munuals I've ever seen, pretty much word for word. To hopefully solve any doubts about the subject I phoned Hornady(800-338-3220) and asked whether or not this data and .268'' bullets would be safe to use in gain twist barrels. The technician I spoke with(Brad) said there would be no problems with using this bullet/data combination in ANY CARCANO(Vetterli's are not Carcano's) w/gain twist barrels providing the rifle is in good condition and the exact components shown were used with exception to the brass where PRVI cases could safely be substituted for the Norma's. What about all other load data? Theres only one rifle shown as the test platform, does that mean 8x57 data developed in a K98kis unsafe for use in any other variant of M98 Mauser or in modern sporting rifles of the same caliber?
