[QUOTE="Freebore, post: 443512, member: 873"] You can probably use this data available here; [url=http://stevespages.com/308_3.html]308_3[/url] It sounds like your cartridge is just a necked down 338 Win Mag case to 30 caliber with maybe some shoulder angle changes. You'll have to compare a 'factory' 338 Win to one of your empty cases to see the differences but I'll bet it's just a necked down .338 case to take .308 bullet. Should be, performance wise very similar to the 308 Norma although the 308 Norma Magnum brass is .060 longer. I'd bet you could get the 308 Norma Magnum brass and a little bit of case prep end up with a really good brass. Just have to find some 308 Norma Mag brass..made by Norma. Or... stick with simple and just get some 338 WW brass run them thru the die. If there is a shoulder angle change it will fire-form out first firing....just like any other Ackley chambering. WW brass is pretty good in itself. I'm sure the cartridges your grandfather had loaded would shoot just fine as long as they were kept in a controlled environment (outside shed vs. a dry cool basement). I mean you may have a very accurate load at least for the 150. Try 3 of them. Clean the rifle first...making sure the chamber is clean also. I would if I had that chamber try the 190 SMK to shoot cross canyon. One more thing if it's a Springfield action..alot of guys after WWII came back from the war and re-chambered the old 30-06's into the 308 Norma Mag. You should have someone like a competent gunsmith just look it over and confirm my suspitions of just what you do have. [/QUOTE]
