2400 IS position sensitive

Some of you may have read my recent posts on my 200 yd match shooting adventures with an '03 Springfield. Also my MIS-adventure with a 1917 Enfield--ie. having a bullet lodge in the barrel and bringing a abrupt halt to a match. Well, yesterday I was feeling good and off to a fair start in a match with the '03 when the last shot of the offhand stage fizzled--no sound that I could detect wearing double hearing protection. Familiar with this after the 1917 incident, I figured “Damn, I'm out of another match with a bullet stuck in the barrel again.” Another shooter said the guys in the range shack have a rod and sure enough, a few taps with a heavy hammer and I was back in business. Returning to the line I still had time remaining to get off my last shot--an eight since I was a little rattled, but at least not a miss. Well, now we're into the sitting rapid and on my fifth shot of the string same thing--no sound other than that of the striker. I did drop out of the match at this point--no time to make another trip to the range shack plus I was demoralized thinking “How many more times is this going to happen?” Back home I was all set to have to tap out another lodged bullet when I discovered the bore was clear--the last shot had just enough uumph to get out of the barrel. Meantime, and all the way home--a 90 mile drive which included a “longcut” over the coast range to avoid horrendous beachgoer traffic--I had been mentally beating myself up, thinking there must be some flaw in my loading technique or routine. Especially after the incident with the 1917, I had been particularly careful when charging my cases. I use a Belding & Mull measure, which means that I'm seeing a full charge (16g of 2400) go into each case, plus I double check by dropping a marked pencil into each case. My respected mentor Frank Craig says that it must be that the charge in the faulty rounds is all the way forward and not igniting properly. Makes sense, as my cartridge holder (for offhand) holds the rounds base up and the action of rapidly chambering a round in RF throws the charge to the front of the case. I had been in the habit of rotating the rounds in the offhand and slow prone stages with my thumb a turn or so before chambering but maybe I got careless and forgot this. Anyway, I think this shows that the position of a light charge in the case can result in misfires--if all the way forward. Mind you, I had shot three previous matches with the same load without a hitch--and had decided on using 2400 because it was reputed to be “position insensitive” I'm going to try RL-7--Frank says about 25g--hope to avoid any recurrences of this problem.
