[QUOTE="codyadams, post: 1635219, member: 87243"] Totally understand if you don't want to fireform, but you will gain way more than 50 fps by improving a 30-338 Lapua. If you look at the standard 338 Lapua vs the 338 Lapua imp, the difference is 2750-2775ish w/300's up to around 2950 fps with the same bullet/barrel length, so more like 175-200 fps, and this is documented in many different rifles. I personally like the aggressive shoulder angle, as it reduces the need to trim brass drastically. One fireform, even just a good COW fireform, and you can load full power loads consistently. You would have no problem hitting 3000 fps with a 250, and you could do it at a lower pressure than a rum or norma, and help with barrel and brass life, which with Lapua brass running lower pressures, would be outstanding. 100 pieces would likely last for the life of the barrel. I would go 30-338 Lapua Improved, but I don't mind foreforming, I have a .260 AI and am in the process of putting together two .270 Shermans for my cousins. Some would advise against it, but you could build a 30-338 LAI on a standard rem 700 action, many smiths (as well as Remington arms company....) builds 338 lapua's on rem 700's, and go with the light fill in the stocks, as it's not the up-sized action. Just my thoughts. [/QUOTE]
