[QUOTE="freebird63, post: 405216, member: 22102"] I have installed the wyatt window box myself, was not as bad as I was thinking it was going to be. Somewhere I read where someone was commenting on how the hornady OAL gauge was not very accurate so last night I loaded up some dummy rounds and checked for myself. With the hornady gauge it showed my rounds with a 210gr berger to be and thats measuring with a comparator, 3.155 inches. Well when I loaded up the dummy rounds last night boy was I in for a big shock. With the dummy rounds to the lands is actually 3.200 inches. Base to tip being 3.900 inches. So that window box I installed will not allow for the rounds to be put in the magazine. So now I have to more or less start my load development all over again. I hate it when that happens. Actually it won't be that bad as I already know that .090 off the lands shoots pretty decent. So now I just have to go back and try at the lands(3.200), .010(3.190), .020(3.180), .030(3.170), .040(3.160). So that should be fun. I finally might get the groups I have been trying for. [/QUOTE]
