you know i have a weatherby vangaurd in 270 wsm and it has feeding and ejection problems to, when i work the bolt slowly it never kicks the shell out properly and sometimes it kicks the shell into a weird position. i managed to fix it by hand jewelling the bolt, a few part of the internal clip itself and the chamber (but i didnt polish it much) it still has the problem sometimes but its rare now. when my older brother (i am using his account now) know alot about this stuff, he says it might be the delta L problem, because of the heavy shoulder and poor standarizations between the saami and the c.i.p. neither of the 2 truely know the maximum pressure or the maximum presure is different between the two. so when you try to eject the casing with the different shoulder angle, it could eject funny and/or effect the way the next bullet aligns with the chamber. ps the shoulder should be 35 degrees and the case length should be 2.1 inches, now i am now sure what the proper length and angle of the shoulder of a fired 270 wsm should be but i found that the shoulder is about 35.6 degrees and the case is 2.2 inches after being fired. so that could be the problem. hope this helps
