I have just got my fireform gun done in what we are calling 300 FOG. It is an improved 300 norma, and I have made 80 pieces of brass so far. I use 338 norma since this way my false shoulder is all ready there to headspace from. Ever since Shawn showed me a 338 norma case, I wanted a 30 for the big bergers.
So far the fireforming load has shot a .115 and a .225, this is with 220 scenars @ 2943. I couldn't help myself, so I made up a ladder with 5 brass. 230 hybrid targets ahead of 96,97,98,99, and 100 grs of 33... I hit pressure at 100 by feel AND measurement of the head. My workable velocity will be about 3,160 and down, the top load (too much) went through the ohler at 3,205. Looks like my 338 LIMP might just be a shelf piece!

Going next weekend to get the real ones, sister rifles for my buddy and I.
