[QUOTE="TOM H, post: 1029988, member: 306"] I'm shooting a 1/12 twist barrel @26" chambered for the 30-338mag and 1/11 twist barrel @ 25" also chamber for the 30-338mag. My latest build is 270Wby and that rifle started life with 1/10 twist barrel @ 26" chambered for the 30-338mag and all three rifles build by different gunsmiths. 1/11 twist barrel, 73gr/H-4831sc with 180gr bullet @ 3034fps and 75gr/H-4831sc with 165gr AB @ 3188fps. 1/12 twist barrel, 70gr H-4831 with 200gr @ 2835fps,73gr/H-4831 with 180gr bullet @ 3017fps. the 1/10 twist barrel not going to put up any loading data but was on par with other 30-338mag. I also use Fed 215 primer 1/11 twist barrel and Rem 9.5M with 1/12 twist barrel. Mine are hunting rifle. Fred Huntington RCBS chamber first rifles for the 30-338mag and my loading data came from Fred Huntington JR and my first one was chambered just like he was. My other two chambered same way. I never kept up with 30-338mag that Rem chamber 40x in or it as a match rd. I'm sure someone would have reamer print on 30-338mag Huntington did and if that's what you wanted get a copy compare to your chamber. [/QUOTE]
