[QUOTE="Rocky Mountain, post: 502731, member: 26832"] Thankyou Kirby for puting some light on my questions. My 338-416 imp dose have a shortish neck with a little wider body than the Excaliber giving similar if not a little more volume than the basic 338 Excaliber. Yes 416 is a alot of work to neck down over the 338-378 but not having a belt is an advantage and with the good 416 jamison brass can handle I believe more pressure. Lastly I can see your new Excaliber design will have about 0.080 longer body length than mine giving 3-4 grains more volume which I'm picking will get you just over 3100fps. So fitting nicely between the lapua and cheytac improved versions giving about 30-50fps extra velocity over my design. Good luck with your new action and excaliber designs I can see Jamison getting Quite a few orders for there new 338 excaliber brass for wildcating. [/QUOTE]
