[QUOTE="Swamplord, post: 1512821, member: 2460"] Ryan Pierce at Piercision Rifles builds a 30 degree 300 Norma Mag Improved that fires factory 300 Norma ammo to fireform, can load up straight factory fresh 300 Norma Mag brass and fire in chamber safely, he's been using the new Lapua brass My 300 & 338 Imp are a bit different with 35 degree shoulders moved up for max capacity so they require a false shoulder for cow forming or bullet into rifling .... they feed smooth out of the DSSF 3.850" Accurate Mags and I have been using my 338 Precision Rifled Ordnance for hunting the last two years, I retired my 338 Edge because of the 338 NM Imp as I mentioned before on a thread here on this site, all of the improved versions off the 300 & 338 Norma Mag parent cases will perform very close to each other, they will vary by a grain or two in h20 capacity but it's not much to make any difference, most of the difference in velocity will be due to barrel length and freebore length in the chamber I've been messing with 250 pcs of the new Peterson 300 NM brass and have mangled it into my improved wildcats in 257, 6.5mm, 7mm, 30 cal, 8mm, 338, 375 and 408 cal, excellent stuff to wildcat from also did same with 200 pcs of the Lapua 300 Norma Mag brass I was fortunate enough to get from Ryan Pierce some time back, excellent stuff as well and can't wait to see the 338 NM brass out from Lapua [/QUOTE]
