[QUOTE="chrisb97, post: 2827413, member: 102205"] During initial load testing I followed cutting edges recommended bullet seating procedures and ended up with my seal tite band right up close to the case mouth. I initially started off with magpro at 94 grains and worked up to pressure signs at 99. In between 96.5 and 97.1 the groups closed up to half inch and going further they started opening back up. My chronograph was reading 2690 and at top end loads was pushing 2750. I am using a forster benchrest seating die and full length resizing every time. I'm gonna get ahold of my gunsmith and see if I can get the measurements for the throat and how far up he cut the lands for the 350 matchking to be seated at 4.1". When I load a bullet in a partially resized case to get an oal measurement it looks like my seal tite isn't touching the bore and the olive makes contact with the lands first, but the seal tite might just be pushing into the bore with not enough resistance, hence why I'm gonna get ahold of my gunsmith [/QUOTE]
