[QUOTE="jmden, post: 321345, member: 1742"] BMcKell, I'm not B23, but have done quite a bit of work, as has he, in figuring this stuff out. You will need to fireform your own Lap Imp brass, unless your smith will do that for you. Not to say that others won't, but I haven't heard of any smiths doing this for customers, except Kirby. This is one reason I went with Kirby, because I can send him Lap brass, and for a reasonable fee, he will get the brass fireformed to fit the 338 AX chamber. One less thing I have to mess around with. Alternatively, fireforming using the COW method, or just filling up your case around 60-70% with a pistol/shotgun powder, sticking a wad of TP or kleenex in the case neck (no TP can protrude to the exterior of the neck), holding the rifle vertically and touching them off, is pretty straightforward--this is the method Boss Hoss mentions here that Speedy Gonzales using and I've found that it's very straightforward and simple. Just an fyi--I specifically did not go with the TAC 338 action as Jerry said that it would not accomodate a 4" Wyatt's mag box.
