had a buddy measure for my oal on my gap rifle using a sergoen action and he came up with a oal touching the rifling with a 175g smk at 2.150 measured from the ogive. this seems to be very short but he knows what he is doing and we measured it 3 times to check ourselves. when loading the rounds i would need to be at 2.148 wich seems to be very short? any info on this or any ideas would be great.
