[QUOTE="barefooter56, post: 1078041, member: 85389"] Ghost7, General rule of thumb is at least 1 caliber of bullet in the cartridge case. 2 is better. What you may want to do in your case . since you are dealing with a short bullet is to start at the published magazine length and work out in .001-.005 increments at the lowest powder charge listed for your bullet/powder/cartridge combination you are testing for. Be sure the barrel of the rifle has been fouled by shooting at a practice target until the bullet strikes stop rising on the target and begin to cluster before doing your group shooting. After you have found your bullet seating depth accuracy node . then work the load back up in 1/2 grain increments until you get to 2 grains below maximum then drop to 1/10th grain increments. All the while you will be checking for pressure signs and accuracy. Another thing to try if nothing seems to work is another brand bullet in the same weight range. There is that intangible of "bullet to bore fit". [/QUOTE]
