[QUOTE="J E Custom, post: 376322, member: 2736"] For the best quality and longevity of brass it's hard to beat the Lapua brass with high pressure loads so From what you have said you wanted I would recomended the following. A 338 Lapua mag with a 37.5 shoulder and a minimum body taper of .007 per inch. Also you can use a Weatherby MK5 action because it is longer than other commercial actions buy over .140 Thousandths or use a custom action so you can seat the bullet long. And for velocity have some free bore so pressures can be managed. With the longer actions you won't have to single load if you want to have follow up shots. If I were going to build an all out 338 then I would go larger, but you said you didn't and sticking to your request that is what I would recomend. I have 2 338 RUMs with long barrels and they will shoot well beyond my ability(They are both built on the MK5) and seated long giving them the same performance as the longer 338 seated deep for the standard mag. Just a thought J E CUSTOM [/QUOTE]
